CSO 1

Overview

Destination: Sun-Synchronous Orbit
Mission: Government/Top Secret

Sun-Synchronous Orbit Soyuz Launch Complex Kourou, French Guiana

The CSO 1 (Composante Spatiale Optique 1) satellite is the first of three new-generation high-resolution optical imaging satellites for the French military, replacing the Helios 2 spy satellite series.

Soyuz STA

Family: Soyuz
Configuration: 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.
