IOD-2, Startical’s second demonstrator satellite and part of the EU-funded ECHOES project, will continue validating real-time VHF voice and data communications between aircraft pilots and air traffic controllers from space
Startical, the company created by ENAIRE and Indra, has successfully launched its second satellite, IOD-2, from Vandenberg Space Force Base in California.
The launch of IOD-2 follows the successful deployment of IOD-1 in March of 2025, that already made history by enabling the first-ever VHF voice communications between aircraft pilots and air traffic controllers via satellite, fully compliant with international aviation standards. These milestones accelerate the development of Startical’s future constellation of more than 200 Low Earth Orbit (LEO) satellites, designed to provide real-time VHF voice and data communications and aircraft surveillance, particularly in regions currently without coverage, such as oceans and remote areas.
With IOD-2, Startical intensifies its testing phase to demonstrate robust, real-time aeronautical communications and surveillance services from space. Additionally, it reflects Spain’s commitment and capabilities to innovate in the aerospace sector.
The mission is led by Startical ,while the engineering behind the mission systems and the satellite payload have been developed by Indra, with the support of ENAIRE.
Today, aircraft flying over oceans or remote regions must maintain wide separation due to the lack of real-time communication. Startical’s satellites will change that, enabling continuous monitoring and direct voice contact with pilots anywhere on Earth, allowing faster responses to storms, emergencies, or rerouting needs. It also paves the way for more direct and fuel-efficient routes, contributing to a greener aviation industry.
Like its predecessor, IOD-2 is part of ECHOES, a project co-founded by the European Union under the Connecting Europe Facility (CEF), managed by the European Climate, Infrastructure, and Environment Executive Agency (CINEA) and supported by the SESAR Joint Undertaking.
The project aims to demonstrate how satellite technology can enhance ATM services and reduce environmental impact. Both satellites will continue undergoing test over the South Atlantic, covering airspace managed by the Canary Islands, Azores, Dakar, Cape Verde, and Brazil. Beyond technological demonstration, these real-world tests will help define future international standards for satellite-based air traffic communications.1
The success of IOD‑1 proved that space-based VHF works. With IOD‑2, we advance Spain’s leadership in aerospace technology and reaffirm our mission to be the first company that will provide VHF voice and data global coverage for ATM,” said Juan Enrique González Laguna, General Manager of Startical.
