The elongation constraints between the theatre of operations and the command centres of maritime operations make satellite communications essential. Thus, the naval environment is the first to be concerned by the renovation of satellite communication stations under the Syracuse IV programme.
Syracuse IV will provide the French armed forces with greater secure and protected satellite communications, whatever the threats (interference, jamming, cyber-attacks, etc.), at high speed, thanks to the dual-band X and Ka capability, in all theatres of operations. It guarantees end-to-end connectivity while ensuring the interoperability of the three environments.
Syracuse IV, which ensures the complete renewal of satellites and ground stations, will gradually replace the assets deployed under Syracuse III.
The ground/naval stations enable the transmission and reception of satellite communications. As an expert in satellite communications systems in France and abroad, Thales is a major actor in the Syracuse IV programme and supplies both the space segment and the ground segment. The renovation of all naval SatCom stations, to benefit from the addition of dual-band X/Ka capacity, began in 2018. The Ka-band capacity was validated in September 2022 on the ATHENA-FIDUS satellite for a ground station of a Frégate La Fayette type, demonstrating the feasibility and reliability of the proposed solution.
The multi-mission frigate (FREMM) Lorraine, a pioneer among first rank ships, left the shipyard in November 2022 equipped with Syracuse IV SatCom station.
