Mission
Pléiades-HR 1A, FASat-Charlie (SSOT), 4 x ELISA
- Type: Government/Top Secret
- Orbit: Sun-Synchronous Orbit
Pléiades-HR 1A is the first of two high resolution Earth observation satellites designed by the French space agency (CNES) and manufactured by Astrium Satellites. The ELISA mission consists of four satellites manufactured by Astrium Satellites and Thales Systèmes Aéoroportés for the French space agency (CNES) and the French Directorate General of Armament (DGA). SSOT is an Earth observation satellite manufactured by Astrium Satellites for the Chilian armed forces.
Location
Soyuz Launch Complex
Guiana Space Centre, French Guiana
Soyuz Launch Complex has witnessed the launch of 26 rockets, including 26 orbital launch attempts. While Guiana Space Centre, French Guiana, has been the site for 325 rocket launches.
The Guiana Space Centre is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
Rocket
Progress Rocket Space Center Soyuz STA Fregat
The 2.1a version includes conversion from analog to digital flight control system and uprated engines on the booster and the first stage with improved injection systems. The new digital flight control and telemetry systems allow the rocket to launch from a fixed rather than angled launch platform and adjust its heading in flight. A digital control system also enables the launch of larger commercial satellites with wider and longer payload fairings such as the ST-type fairing. These fairings introduce too much aerodynamic instability for the old analog system to handle. This stage continues to use the RD-0110 engine.
The 2.1a/ST version is sometimes called Soyuz ST-A.
