KSAT awarded with ESA study for future Earth Observation dataflow architecture

February 7, 2023 by editorial

Recently, KSAT became the lead to study the efficient distribution of future ground station locations and use of novel downlink protocols, as prime contractor with partners DLR, Kongsberg Defence and Aerospace and Airbus Defence and Space for this study contract by the European Space Agency (ESA).

The study goal is to refine the future dataflow ground architecture for ESA Earth Observation (EO) satellites and deliver a roadmap for its adaptation in the timeframe 2027. ESA is planning to significantly increase the number of operational EO satellites in the coming years, with the launch of the Copernicus Expansion Missions and the Sentinel Next-Generation Satellites. The evolving landscape of ESA EO will bring a substantial increase to data volume and higher data rate requirements.

The general trend toward higher data rates and higher downlink frequencies (K-band) for ESA institutional EO satellites requires the use of novel protocols to improve the robustness and resiliency of the LEO to Earth communication. In particular, the impact of using communication protocols such as the CCSDS File Delivery Protocol CFDP Class 2 on the ground segment will be assessed in the context of forthcoming fully based DTN-network architectures.

KSAT is currently a core provider of data acquisition and TT&C (Telemetry, Tracking and Control) services for the European Space Agency’s Earth Observation Missions.

“We are very happy to be awarded with this study contract, contributing to the continued success of the Copernicus program,” said Amund Nylund, Chief Operation Officer (COO) at KSAT. “Our global ground station network with antenna terminals on all continents, including Antarctica, is an indispensable asset for LEO Earth Observation missions.”
