February 7, 2022 – Thales Alenia Space has been awarded a contract by the French Space Agency CNES to develop a DFMC (Dual Frequency Multi Constellations) SBAS prototype in the frame of the next generation of SBAS, like EGNOS, the European navigation satellite system. This prototype will complement both GPS and Galileo systems taking benefit of signals transmitted in multiple frequencies for better performances in particular dedicated to aviation navigation and landing, but also to any applications demanding a highly reliable and a highly accurate positioning information. When developed, this prototype will be deployed and tested in an operational mode in real condition using a geostationary satellite. The performances will be analyzed in details according to international standard criteria as accuracy, availability, continuity and service integrity.
