TOULOUSE, France (Exotrail PR) — In February 2022, following a competitive tender process, CNES selected Exotrail to complete a research and technology study to optimise the operations of mega constellations. The study will focus on mid and low earth orbit where thousands of satellites are soon expected to be operational and propelled by electric propulsion. It will determine the best operational procedures to implement in mega constellation’s flight dynamic system including station keeping and collision avoidance – two critical operations.
