Dassault Aviation set up a successful and reliable telemetry infrastructure within Test Flight Directorate in Istres. The company was held for the renovation of the ground telemetry system of Kourou by proposing the technologies and the methods developed for aircrafts.

Dassault Aviation finalized the ground telemetry system of Ariane-5 launcher which allows the follow-up of the launch vehicle around the Earth. It includes the equipment for all stations of Kourou, Natal, Ascension, Libreville and Malindi, as well as the telemetry centralization and exploitation service (French acronym SCET).



Ariane-5 telemetry stations

In 2007, Dassault Aviation saw itself intrusted the adaptation of Nset for the Soyuz launcher. It will allow to diffuse the informations coming from the Russian Soyuz launcher and its Fregat upper stage towards the legal safeguard authority. For the first time, it uses the technology of Ethernet network for the broadcasting of telemetry data via an equipment assuming a better message integrity (separation and independence).



SCET - The network with Earth receiving stations

In 2008, the company was in charge of adapting the Ariane-5's SCET to the Vega European launcher who uses the same telemetry message structure.



Technical support base - This facility is operating in Dassault Istre plant to provide technical assistance to Kourou in real time; it also support the development of Ariane systems upgrades

In September 2008, Cnes renewed its confidence to Dassault Aviation by granting him the contract of SCET Multilanceur (SCET-M) development. The telemetry conceived by Dassault Aviation will be used by the Guyana space center for Ariane-5 but also for the Soyuz (Russia) and Vega ( Europe) launchers who will enter in operation during the 2010/2012 period.
