MOUNTAIN VIEW. The era of cheap, plentiful, and diverse access to space was supposed to be here by now. Instead, the industry arrived at the 2026 SmallSat Symposium only to find itself trapped in a bottleneck of its own making.

During the Small Payloads, Large Upmass session, the polite veneer of industry camaraderie barely concealed the tension in the room. The narrative of a vibrant, multi-provider marketplace has collapsed. In its place sits a single, dominant provider, SpaceX, flanked by a long line of customers paying premium rates to stand in line. While panelists from Rocket Lab, Stoke Space, and European challengers like Isar Aerospace and PLD Space offered visions of a diverse future, the audience is living in a present defined by scarcity.

The Aggregator is the New Gatekeeper

The most telling dynamic onstage was not between the rocket builders but rather centered on the empty chair left by the neutral broker. With the dissolution of Spaceflight Inc.’s independent brokerage model, Exolaunch has emerged as the primary funnel for the industry’s volume.

Kier Fortier, Chief Revenue Officer at Exolaunch, did not shy away from the congestion defining the current market. The days of simply booking a slot and flying are over; operators must now plan for delays as a fundamental business condition.

Fortier stated, “I do think rebooking now is just the baseline expectation to salvage your launch budget.”

This admission signals a profound shift. Launch is no longer a commodity you buy, but a probability you manage. The consolidation of demand onto SpaceX Transporter missions has created waitlists. Fortier noted that despite the high flight rates, “There are folks eager to get up on orbit, and there is some scarcity there.”

The Paper Rocket Problem

This scarcity stems from the simple fact that the challengers are late. Rocket Lab’s Neutron was originally promised for 2024, yet it is now targeting mid-to-late 2026. Brian Rogers, Rocket Lab’s Vice President of Global Launch Services, framed this delay as a necessary hurdle of scaling.

Rogers argued, “Building your first rocket is ridiculously hard. Building your next 10 at rate is actually way harder.”

While Rogers is correct, the market is unforgiving. Every month Neutron remains on the ground is a month where mega-constellations sign long-term contracts with SpaceX’s Falcon 9. The session moderator, Curt Blake, former CEO of Spaceflight, pressed the panel on the risks of a monopoly trap.

Devon Papandrew, VP of Business Development at Stoke Space, addressed the monopoly question head-on. He dismissed the idea that SpaceX’s dominance is accidental or unfair, attributing it instead to technical superiority that others failed to match in time.

“Why is SpaceX a monopoly today?” Papandrew asked, then answered, “They created a step change in capability that unlocked higher cadence and lower cost.”

Stoke Space is betting $510 million that partial reusability is a dead end. Papandrew contended that the only way to break the current pricing floor, now rising toward $6,500/kg, is full reusability.

“If you look what SpaceX has done with Falcon, it’s amazing,” Papandrew said. “But if you ask them what constrains their flight rate, it’s production of the upper stage.”

The Sovereign Illusion

For the European representatives, the challenge is existential. Isar Aerospace, PLD Space, and Avio are fighting for a slice of the market that isn’t captive to U.S. dominance. Yet their value proposition relies heavily on the sovereignty premium—the idea that European institutions will pay more to fly European.

Francesco Sgarbossa, Sales Director for Avio, was refreshingly blunt about the limitations of European cadence compared to the American juggernaut.

“We are aiming at six, which sounds like a very low number when you think about it when you see SpaceX launching 160 times,” Sgarbossa admitted. “But even going from four to six is a 50% increase and that requires huge investments.”

This is the cold math of the 2026 launch market. A 50% increase for Avio is a rounding error for SpaceX. Daniele Dallari of PLD Space tried to reframe the conversation away from mass commoditization, questioning the industry’s obsession with replicating the SpaceX Transporter model.

Dallari asked, “Do we need another Transporter program? Does the market really need another Transporter program?”

The market’s answer, evidenced by the rising prices and full manifests on Falcon 9, appears to be yes. Operators want reliability and low cost. They are less concerned with the bespoke orbital insertions Dallari’s Miura 5 might offer if the price tag is double that of a rideshare slot.

The Ancient Game of Launch Chicken

The friction between satellite readiness and rocket availability remains the industry’s favorite scapegoat. Brian Rogers described the constant shuffling of manifests as a necessary evil.

“We’re no strangers to the ancient game of launch chicken,” Rogers said. “Spacecraft can be late. And that can be a problem when you’re trying to plan a manifest.”

But in 2026, the chicken has come home to roost. The delays are no longer just about spacecraft. The launch vehicles themselves are the bottleneck. The regulatory environment has tightened, and the FAA licensing backlog is real. The flexible slotting discussed by the panel is merely a band-aid for a lack of capacity.

“You got to launch”

The dream of a dozen thriving small launch providers competing on price has faded. The reality is a barbell market: a massive, efficient monopoly on one end, and a collection of hopeful, delayed challengers on the other.

Until Neutron flies, Stoke reaches orbit, and the European launchers prove they can hit a cadence higher than single digits, the SmallSat customer has no real leverage. They will pay the $6,500/kg, they will sign the multi-launch agreements, and they will thank Exolaunch for the privilege of a slot.

As the session concluded, the applause felt less like a celebration of innovation and more like relief that the status quo, however expensive, is at least a known and predictable factor. Curt Blake ended the panel by asking about the challenge to survive. Brian Rogers offered the only advice that matters in an industry choked by promises.

“You got to launch.”

Dispatch from SmallSat Symposium. Coverage and analysis from across the conference, tracking the forces shaping the next phase of the SmallSat market.

MOUNTAIN VIEW. The age of PowerPoint architecture has passed. For five years, the Space Development Agency operated as the Pentagon’s rebellious startup, promising to deliver a Proliferated Warfighter Space Architecture faster than the establishment could draft a requirements document. At the SmallSat Symposium, however, no celebratory mood pervaded the SDA Vision: Pacing Evolving Threats session. Instead, a sober atmosphere prevailed as SDA’s ambitions met the friction of reality.

Dr. GP Sandhoo, the agency’s Acting Director, took the stage at a precarious moment. He leads an organization recovering from a leadership decapitation following Derek Tournear’s departure and simultaneously facing a blistering Government Accountability Office report released just days ago. The report questioned the agency’s handle on technical risk. Consequently, Sandhoo arrived in Mountain View not to sell a vision, but to explain why the “Fight Tonight” mentality is harder to execute than it looks on a whiteboard.

The End of the Commodity Myth

The morning’s most striking admission was the demise of the easy satellite bus. The core thesis of the New Space revolution and the SDA’s acquisition strategy relied on the assumption that commercial satellite buses were commoditized goods, ready to be bought off the shelf like dependable pickup trucks. Sandhoo dismantled this belief with brutal transparency regarding the agency’s Tranche 0 demonstration.

“The biggest challenge we had with Tranche 0 was the buses—spacecraft buses—which were supposed to be a commodity . . . and none of them were,” Sandhoo admitted.

This represents a stark correction for an industry that prides itself on standardization. The Acting Director noted that while the exotic payloads (optical cross-links and Link-16 terminals) performed well, the basic infrastructure failed. He described the “onesie-twosies” failures that plagued the early deployment: “GNC [Guidance, Navigation, and Control] is not working, the thermal is not right.”

The implications for the supply chain are severe. Instead of theoretical speed, the SDA is enforcing rigor. Sandhoo noted that for the currently launching Tranche 1, the agency is behind schedule on checkouts precisely because they are forcing prime contractors to prove their buses work before they fly. “It’s one thing to launch a couple of satellites and kind of go through the whole checkout, it’s another thing to launch 21 at the same time,” Sandhoo said.

The Fire Control Pivot

While bus manufacturers face a reckoning, the SDA’s strategic scope has expanded dangerously close to the nuclear threshold. The conversation’s focus has shifted from warning (seeing a missile launch) to fire control (guiding an interceptor to kill it).

Sandhoo detailed the massive Tranche 3 awards made in December, which split the architecture into two distinct classes. The first is standard missile tracking. The second is the Golden Dome fully realized: a sensor specifically designed to close the fire control loop on hypersonic glide vehicles.

The Acting Director explained the distinction with engineer-like precision: “When you see MW/MT/MD, that takes a step further. That is, you can detect the missile, you can track the missile, but you can also come up with a fire control quality solution on board the spacecraft.”

That sequence presents the strategic edge in action, to which the Pentagon has committed roughly $3.5 billion, awarding contracts to Lockheed Martin and, in a major graduation moment, Rocket Lab for high-fidelity sensors. By trusting Rocket Lab with the defense mission rather than just the tracking mission, the SDA has officially elevated the company from a launch provider to a prime defense contractor capable of handling the DoD’s most sensitive data.

The Commercial Reserve Fleet

Sandhoo also addressed a subtle but critical shift: the enclave strategy. The SDA originally envisioned a self-contained intranet in the sky, but such an isolationist model has become defunct. Now the agency is actively looking to route military data through commercial constellations like Amazon’s Kuiper or the optical meshes of Kepler and Telesat, creating a hybrid space architecture that provides resilience through redundancy.

Using a domestic utility analogy to describe this pivot, Sandhoo stated, “When you have Verizon and Xfinity come to your doorstep, you should start using some of that stuff too to make sure you leverage all those things.”

This hybrid enclave architecture effectively deputizes the commercial sector. By publishing optical and networking standards, the SDA has created a market where commercial operators become reserve nodes for the Joint Force. If a Chinese ASAT weapon takes out a Lockheed satellite, the data could theoretically reroute through a commercial bird.

The Shadow of the GAO

Looming over the technical discussion was the shadow of the recent GAO report, which criticized the SDA for schedule optimism and for buying Tranche 3 satellites before Tranche 1 has proven its technology works. Although Sandhoo did not address the report by name, he noted the acting nature of his role and the budget’s palpable uncertainty.

Sandhoo acknowledged that the speed of acquisition is colliding with the reality of production throughput. “It’s one thing to have a technically ready thing; it is another thing to make 150 of those,” he said.

The Gamma variant of Tranche 2, critical for the advanced fire control mission, remains delayed following the Viasat protest and the subsequent leadership turmoil that ousted Dr. Tournear. Sandhoo nonetheless projected confidence in face of the undeniable friction, observing that due to competitive pricing, Tranche 3 proposals allowed SDA to buy 72 satellites instead of the planned 54.

The Verdict

The startup phase is over. The SDA is now a utility provider for the Combatant Commands. As Sandhoo put it, the goal is no longer simply to disrupt, but to pace the threat.

For attendees at the SmallSat Symposium, the message was clear. The government checkbook is still open, but the days of selling beta-test hardware are over. If you cannot build a bus that reliably handles thermal loads, or an optical terminal that instantly locks in a hostile environment, do not bid. The Golden Dome is being built, but the SDA is done laying bricks that crumble under pressure.

On January 28, 2026, Astroscale France and Exotrail announced a strategic partnership to develop and demonstrate controlled deorbiting capabilities for satellites in Low Earth Orbit (LEO).

The collaboration aims to address increasing orbital congestion by providing a repeatable, sovereign European solution for satellite end-of-life management and debris mitigation.

Building on the CNES France 2030 Study

The partnership follows a successful study phase led by Exotrail under a France 2030 contract with the French space agency, CNES. During this phase, the two companies evaluated a deorbiting mission for a constellation satellite, laying the groundwork for the current operational roadmap. The initiative is closely aligned with European space priorities regarding technological sovereignty and the “circular space economy”.

“By combining Exotrail’s mission leadership on vehicles and maneuvers with Astroscale’s proven capture and close-proximity operations expertise, we are helping to position France and Europe at the forefront of in-orbit servicing,” stated Philippe Blatt, Managing Director of Astroscale France.

Integration of spacevan and RPO Technology

The technical core of the partnership relies on merging Exotrail’s mobility platforms with Astroscale’s specialized servicing hardware:

• Exotrail spacevan: A high-mobility orbital transfer vehicle (OTV) capable of significant altitude and inclination changes. The spacevan LEO offers a delta-V of 500 m/s and is designed to act as a mission integrator and “last mile” delivery vector.
• Astroscale RPO & Capture: Drawing on flight heritage from missions like ADRAS-J and ELSA-d, Astroscale France provides the critical Rendezvous and Proximity Operations (RPO) algorithms and docking mechanisms required to safely secure a target.

Rationale: Resilience of European Space Architecture

The move to operationalize deorbiting services reflects a shift in how satellite operators and governments view the life cycle of space assets. As LEO becomes more congested with mega-constellations, the ability to actively remove non-functional hardware is transitioning from a research interest to a regulatory and operational necessity.

“Controlled deorbiting and on-orbit rendezvous capabilities are now recognized as critical technological building blocks, for both civilian applications and the future of defense endeavors,” added Jean-Luc Maria, CEO of Exotrail. “We add more capabilities to strengthen the resilience of European space architectures”.

Timeline to 2030 Demonstration

The partners intend to execute their first joint demonstration mission before 2030, which will target the removal of a commercial satellite currently in orbit. Beyond this initial proof-of-concept, the collaboration includes a long-term shared roadmap to establish permanent European rendezvous and docking infrastructure, supporting future in-orbit assembly, refueling, and maintenance missions.

On January 28, 2026, Silicon Sensing Systems Ltd announced the appointment of Bizmile Co. Ltd as its exclusive distributor in South Korea, marking the company’s first official entry into the Asia-Pacific (APAC) market.

The agreement expands Silicon Sensing’s global footprint to 15 countries and increases its total distributor network to 21 partners.

Strategic APAC Expansion

Based in Plymouth, UK, Silicon Sensing is a joint venture between Collins Aerospace and Sumitomo Precision Products. The partnership with Bizmile is designed to capitalize on the rapid growth of South Korea’s aerospace and defense sectors, where there is a rising requirement for high-precision inertial solutions.

Bizmile already maintains a robust presence within the Korean defense market, representing several international component manufacturers. Under the new contract, the firm will provide local manufacturing, integration, and marketing services for Silicon Sensing’s product line.

“As global demand for inertial solutions continues to grow, we’re strengthening our distributor network to ensure customers worldwide have easy, reliable access to our products,” stated David Somerville, General Manager of Silicon Sensing Systems Ltd.

High-Precision MEMS Technology

Silicon Sensing specializes in Micro Electro-Mechanical Systems (MEMS) technology, specifically for navigation and stabilization applications. The company has supplied millions of units globally since its inception in 1999.

• Key Product Focus: MEMS gyroscopes and accelerometers designed for high-precision motion sensing.
• Form Factor: Solutions are engineered in compact, robust packages suitable for integration into complex aerospace platforms.
• Market Applications: Targeted toward leading programs in South Korea requiring stabilized navigation in challenging environments.

Growth Outlook for South Korean Defense

The appointment comes as South Korea continues to invest heavily in indigenous aerospace programs and defense modernization. By establishing a local representative in the region, Silicon Sensing aims to streamline the procurement process for Korean businesses and government entities seeking ITAR-free or high-reliability inertial components.

“South Korea’s aerospace and defense sectors are growing rapidly and we see a strong demand for our inertial products in these markets,” added Somerville.

Chris Forrester — The news that Eutelsat has ordered 340 new OneWeb satellites, additional to its existing contract for 100 extra craft, secures the company’s future and can only benefit revenues once the fleet is in operation.

The 340 will guarantee Eutelsat’s existing services although at a cost of around $2.56 billion (€2.2bn) plus the cost of launches. Some of those launches are already booked. Eutelsat ordered about ten launches (“multiple launches”) from MaiaSpace to deploy a portion of the 440 new OneWeb satellites. Launches are scheduled from late 2027 to 2029. MaiaSpace thus secures 50 percent of the planned launches over the period.

MaiaSpace was founded in 2022 as a wholly owned subsidiary of ArianeGroup. The company is developing a two-stage, partially reusable launch vehicle called Maia, designed to deliver up to 4,000 kilograms to low Earth orbit when flown in its expendable configuration with the optional ‘kick’ stage.

The first 100, needed to ensure continuity of service, were ordered in December 2024 but observers say that the satellite operator needed to put its own finances in order before it could order the additional 340.

Eutelsat restructured its core finances by raising €1.5 billion in December 29025, including an extra chunk of capital placed into the operator by the French government which as a result now controls 29.65% of Eutelsat.

The new order will be fulfilled by Airbus Defence & Space at its Toulouse, France, facility, and the first batches should be ready for launch towards the end of this year. These early launches will replace OneWeb satellites launched in 2019 and 2020 and now reaching the end of their planned lives.

In its January 12 statement Eutelsat said the new fleet would integrate technology upgrades including advanced digital channelisers, enabling enhanced on-board processing capabilities as well as greater efficiency and flexibility and suggesting that the new craft could carry ‘hosted payloads’ for the French military.

Indeed, Eutelsat is reportedly talking to other European defense ministries and pitching similar options for dedicated payloads.

But there’s certainly going to be a slight disappointment for French pride in that the order has gone to Maia Space. Despite Maia being an Ariane subsidiary, some would have preferred Arianespace itself to be a carrier. There’s also the underlying fear that other rocket providers will be called upon to fill the gap given that Ariane itself is fully booked for 2026 and much of 2027 on other non-Eutelsat contracts.

Consequently, Eutelsat CEO Jean-François Fallacher might have to select SpaceX – which can carry 45 OneWebs – will be called into play. However, it is worth remembering that Eutelsat still has a contract in place with Jeff Bezos for a flight on Blue Origin’s New Glenn rocket. The contract was signed with much fanfare at the 2017 Washington Satellite Show by Rodolphe Belmer, then CEO at Eutelsat, and with Bezos.  It could well be that a New Glenn launch during 2027 could carry OneWeb satellites.

The new OneWeb contract is just the first stage of Eutelsat’s growth plan. The next step, now being made with the SpaceRISE consortium of which it is a key part, is the important European IRIS² multi-orbit highly-secure satellite scheme. IRIS², backed by the European Commission and European Space Agency but also with plenty of private cash from the likes of SES, Eutelsat and Hispasat, calls for 272 satellites in LEO (at 1200 kms) and 18 in MEO (at 8000kms). They would operate with laser connectivity.

The IRIS² contract was signed with the SpaceRISE consortium which has to design, deliver and operate the Infrastructure of Resilience, Interconnectivity and Security by Satellite (IRIS²) for a concession period of 12 years.

Eutelsat has to pay for its place in the consortium, and is said to be in talks with financing sources including the French BPIFrance and EK Export Finance agencies.

SpaceRISE issued its Requests for Proposals (RFP) on December 28 2025 to Europe’s satellite builders and launch suppliers, and there’s a requirement that some 30% of the satellite contract value must go to small and medium-sized industry businesses.

These combined elements will keep Eutelsat busy for a year or two, but its OneWeb revenue growth should help fund expansion. Eutelsat says it expects its LEO revenues to grow by around 50% – and possibly more – as 2026-2027 unfolds. Eutelsat is targeting total revenue of between €1.5 billion and €1.7 billion by the end of 2028-2029. Much of that will come from OneWeb.

With the first OneWeb launches now likely to take place before calendar year-end 2026, Eutelsat’s revenue stream should grow commensurately.

JÜLICH, Germany — On Thursday, January 15, 2026, NASA selected the AtmOCube (Atmospheric Oxygen CubeSat Mission) as part of its Heliophysics Flight Opportunities for Research and Technology (H-FORT) program. The international mission, led by Forschungszentrum Jülich (FZJ) in collaboration with the University of Wuppertal and the University of Colorado Boulder (LASP), will investigate how atmospheric gravity waves disrupt satellite operations and navigation signals.

16U CubeSat Technical Parameters

The mission utilizes a 16U CubeSat designed to operate at an altitude of approximately 500 kilometers. The satellite’s primary payload is an optical interferometer developed by FZJ and the University of Wuppertal. This instrument observes the natural infrared radiation of oxygen in the upper atmosphere to obtain high-resolution temperature profiles. By measuring these profiles, researchers can derive the spatial structure and energy flow of gravity waves—disturbances generated in the lower atmosphere that propagate upward to influence the thermosphere and ionosphere.

Advancing Ionospheric Predictive Capabilities

AtmOCube builds upon nearly a decade of collaborative research between German atmospheric physicists and U.S. space laboratories. Previous iterations of the technology, such as the AtmoCube A1 interferometer concept, were designed to resolve individual emission lines within the oxygen A-band. The current mission seeks to bridge a critical data gap regarding how these waves trigger variability in air density, which directly impacts satellite drag and the reliability of Global Positioning System (GPS) transmissions.

Scientific Leadership on the Selection

“The selection by NASA is a big step for our team and our partners. AtmOCube combines innovative measurement technology with clear social relevance,” said Prof. Dr. Michaela I. Hegglin Shepherd, Director at the FZJ Institute of Climate and Energy Systems and project lead. “The scientific data helps us to make predictions for future satellite operations more reliable while also helping us understand how climate change in the lower atmosphere continues into near-Earth space.”

Timeline for Concept Refinement and 2029 Launch

Following the NASA selection, the AtmOCube team will enter a six-month concept and planning phase. This period will involve refining mission requirements and addressing feedback from the initial review process. The phase will conclude with a System Requirements Review (SRR), which serves as the gate for NASA’s final approval for construction and implementation funding. The mission is currently manifested for a 2029 launch.

AMSTERDAM — With the European space sector undergoing a structural shift toward security and autonomy, organizers of SmallSat Europe 2026 have issued a final call for technical papers. The deadline for abstract submissions is January 23, 2026, leaving engineers and researchers less than two weeks to propose presentations for the continent’s largest dedicated small satellite conference.

The event, scheduled for May 26–28, 2026, at the RAI Amsterdam Convention Centre, is projected to host more than 2,500 attendees, doubling the participation of the 2025 edition. The expansion reflects the region’s urgent focus on dual-use capabilities and sovereign infrastructure, a theme that has replaced the theoretical commercial discussions of previous years with hard requirements for resilience and rapid deployment.

From Theory to Requirements The 2026 technical agenda highlights the engineering challenges inherent in Europe’s new strategic posture. Key solicitation topics include sovereign connectivity architectures, underpinned by the EU’s IRIS² program, as well as alternative positioning, navigation, and timing (PNT) systems independent of GPS.

This pivot aligns with the recently established EU Space Defence Track, a partnership designed to address the integration of commercial technology into military frameworks. Organizers are specifically seeking papers that address defense-civil fusion architectures, cybersecurity for contested environments, and on-orbit AI for threat detection.

Submission Guidelines Technical papers will be presented during 15-minute oral sessions or poster displays and published in the official conference proceedings. The program committee has emphasized a preference for active engineering results over marketing-driven concepts.

• Systems Design: Integration of sovereign payloads and secure buses.
• Ground Segment: Architectures supporting multi-orbit constellations (LEO/MEO).
• Operations: Autonomy and data processing in high-latency or denied environments.

Timeline and Deadlines

• Abstract Deadline: January 23, 2026
• Acceptance Notification: February 20, 2026
• Final Paper Due: April 30, 2026
• Conference Dates: May 26–28, 2026

Submissions can be made directly via the SmallSat Europe website.

BEIJING – In a significant escalation of the orbital broadband race, China has submitted a major regulatory filing with the International Telecommunication Union (ITU) for a massive satellite constellation totaling approximately 200,000 spacecraft.

The move highlights a strategic ambition to deploy a network that would quadruple the current long-term deployment goals of SpaceX’s Starlink, which is working toward a 50,000-satellite architecture.

The filing indicates that China is moving to operationalize a parallel commercial launch sector, often referred to as a “Shadow Starlink,” to compete directly with Western Low Earth Orbit (LEO) dominance.

Geopolitical Competition in the LEO Sector

This development validates the ongoing “Surge” strategy from Chinese space authorities, specifically focusing on the G60 Starlink and Guowang projects. By filing for such a high volume of orbital slots, China is positioning itself to challenge the primary-occupant status currently held by the United States and its commercial partners.

The scale of this competition directly impacts several industry layers:

• Regulatory Oversight: Increased pressure on the ITU to manage orbital debris and spectrum allocation for hundreds of thousands of active nodes.
• National Security: The Federal Communications Commission (FCC) has expressed concerns regarding the geopolitical implications of a Chinese-controlled global broadband network.
• Commercial Viability: The massive influx of capacity could fundamentally alter the economics of global satellite internet pricing.

The Rise of the G60 Breakout

The filing is part of a broader trend where China seeks a “breakout” from traditional state-run space operations to more agile, commercially modeled constellations. This “G60 Breakout” represents a move toward high-cadence manufacturing and launch capabilities intended to match the vertical integration of the “Musk Stack”.

The strategy focuses on building domestic launch hubs and satellite production facilities that can output thousands of units annually, a necessity if China intends to populate even a fraction of the 200,000 slots requested in the ITU filing.

Outlook: Regulatory and Orbital Hurdles

As China and the U.S. move closer to a 2027 milestone for constellation maturity, the international community faces unprecedented challenges in space traffic management. While the filing for 200,000 satellites represents a declaration of intent, significant technical and regulatory hurdles remain before such a fleet can be successfully deployed.

Future scrutiny from the ITU and the FCC will likely focus on the “bring-into-use” (BIU) requirements, which mandate that a percentage of the filed satellites must be operational within a specific timeframe to retain the spectrum rights. Failure to meet these milestones could lead to a significant reduction in China’s authorized orbital capacity.

The UK Space Agency (UKSA), acting on behalf of the Home Office’s Emergency Services Mobile Communications Programme (ESMCP), has officially invited industry input to integrate satellite direct-to-device (D2D) technology into the national Emergency Services Network (ESN).

The move aims to leverage Low Earth Orbit (LEO) constellations to eliminate terrestrial coverage gaps that have plagued the project for over a decade.

Solving the “Final 5%” Coverage Gap

The ESN is intended to replace the aging Airwave TETRA-based radio system with a modern 4G/5G platform provided by EE (BT Group). While terrestrial infrastructure covers most of the population, significant “not-spots” remain in rural and coastal areas.

By utilizing D2D technology, the UKSA hopes to provide emergency personnel with seamless connectivity using standard smartphones, bypassing the need for specialized satellite handsets or external antennas. The integration focuses on Mission-Critical Messaging, SMS and location data in remote locations.

Further, future-proofing for high-bandwidth video and voice-over-LTE via satellite as constellations mature. Providing a redundant backup to terrestrial cell towers during network outages or natural disasters will be a critical component of the project.

Key Contenders and Partnerships

Several major space players are positioned to support the ESN expansion:

• SpaceX (Starlink): Currently the most mature D2C provider. Notably, BT Group (EE’s parent company) signed a broadband agreement with Starlink in 2025, making them a front-runner for any ESN satellite extension.
• AST SpaceMobile: Partnered with Vodafone Group, AST expects to provide “intermittent nationwide” LEO service in 2026, with continuous service planned for later in the year as more BlueBird satellites are deployed.
• Eutelsat OneWeb: The UK-backed LEO operator is also developing D2D capabilities to complement its existing enterprise and government broadband offerings.

Regulatory and Program Milestones

The timing of the UKSA’s request for information coincides with Ofcom’s new regulatory framework, which came into force in late 2025. This framework allows Mobile Network Operators (MNOs) to use their existing terrestrial spectrum for satellite-to-phone links, removing legal barriers for a 2026 commercial launch.

However, the ESN project itself remains a “high-risk” endeavor. Originally slated for 2017, the full transition from Airwave is now not expected until December 2029, with total program costs estimated to exceed £11 billion.

Looking Ahead

The Home Office is currently finalizing a £1.11 billion framework for ESN-compliant end-user devices, which is expected to be awarded in summer 2026. These devices will likely be the first to feature the integrated satellite-terrestrial roaming capabilities currently being explored by the UKSA.

December 25, 2025, Operational signals from the SpaceRISE consortium—comprising SES, Eutelsat, and Hispasat—indicated the multi-orbit IRIS² (Infrastructure for Resilience, Interconnectivity and Security by Satellite) program has transitioned into the active procurement phase.

The consortium has begun the preparation of Request for Proposal (RFP) documentation for both satellite hardware and launch services, marking the first significant movement toward physical acquisition since the signing of the concession agreement.

The shift into procurement was confirmed by recent talent acquisition requirements at Eutelsat, where newly appointed procurement and system engineering roles are tasked with the immediate “preparation of the satellite and launch services RFP.” This phase follows the signing of a 12-year concession contract between the European Commission (EC) and SpaceRISE on December 16, 2024, which allocated approximately €10.6 billion for the development and operation of the sovereign European constellation.

Strategic Transition to Hardware Acquisition

The initiation of the RFP process suggests that the “competitive dialogue” stage—previously focused on narrowing the field of prime contractors for the Low Earth Orbit (LEO) segment—is reaching a conclusion. As of late 2025, the competition for the LEO segment was centered on two primary bidders: Airbus Defence and Space of France and Aerospacelab of Belgium. The current procurement push indicates the consortium is moving beyond design reviews to finalize contractual awards for the manufacturing of the 272-satellite LEO fleet.

The IRIS² program serves as the European Union’s flagship initiative to establish a secure, multi-layered communications backbone. By integrating the existing LEO expertise of Eutelsat (via its OneWeb assets) and the Medium Earth Orbit (MEO) capabilities of SES, the architecture aims to provide resilient governmental communications and bridge the digital divide for EU member states.

Technical Architecture and Mission Parameters

The planned constellation will utilize a multi-orbit architecture to ensure continuous coverage and high-performance throughput:

• LEO Segment: 272 satellites at an altitude of 1,200 km, designed for low-latency broadband and 5G-equivalent connectivity.
• MEO Segment: 18 satellites at an altitude of 8,000 km, leveraging SES’s established orbital infrastructure to provide high-capacity throughput.
• Inter-Satellite Links: The fleet will employ optical laser technology to maintain mesh network connectivity, reducing reliance on terrestrial ground stations outside of European borders.
• Sustainability: Consortium members have committed to non-emissive satellite designs to minimize interference with astronomical observations and strict debris mitigation protocols.

“IRIS² is integral to Europe’s space strategy and is already fostering enhanced collaboration and innovation between the industry and public sectors,” said Adel Al-Saleh, chief executive officer of SES, during the program’s initial contract signing.

Timeline to 2030 Operational Status

The next milestone for the SpaceRISE consortium involves the evaluation of the upcoming satellite and launch RFPs. While the European Commission targets initial governmental services by 2030, the 2026–2027 period is expected to focus on the Critical Design Review (CDR) and the first batch of satellite manufacturing.

The launch services RFP will likely prioritize European launch vehicles, specifically the Ariane 6, to maintain the program’s mandate for strategic autonomy. Full operational readiness of the constellation remains slated for 2031, following a phased deployment beginning in late 2029.
