The French Company DASSAULT (as prime contractor) and GTD, together in commercial partnership, have been awarded with a new contract, for the design, development, delivery and commissioning of the ARIANE, VEGA and SOYUZ Telemetry Data Centralisation and Exploitation System (SCET) The project duration is 41 months with a project budget of 4,3 M€ for the baseline including a conditional phase related to the adaptations needed for the SOYUZ launcher. the telemetry system which is used to acquire, record and restore both in real time and later any information transmitted by the launchers. Telemetry is information recorded on the launcher by sensors then formatted and transmitted to the ground trough a radioelectrical link. Once decoded, this information on the different launcher components during the flight is either processed and exploited immediately on the ground (real time analysis), or recorded for more thorough analysis later (offline analysis) This system, to be installed in European Space Port in French Guyana, is the responsible for acquiring, recording, transmitting and processing Ariane, Soyuz and VEGA telemetry. This includes : · recording all telemetry from the freeing of the inertial measurement units until the end of the launcher mission and transmission to a processing centre located in metropolitan France, · real-time control by Arianespace of launcher operations and of the sequence of programmed events (mainly separations), drawing-up of a ‘satellite positioning report’ indicating the orbits and attitudes of satellites after positioning.
