SPOT 1/2, ERS1 In Orbit Technological Exploitation

The main goal of the in-flight experience feedback is to improve the design of the next generation of satellites with regards to the current one.

This experience is gained through detailed analysis of the telemetry data originated from the satellites currently under exploitation.

The comparison between the in-flight performances and the initial predictions allows to reach some of the main following objectives:

• to improve the knowledge of the real in-orbit behaviour of the satellites and in particular of those issued from the same family,
• to update the specifications used for the design of the satellites,
• to validate and improve the simulation and prediction tools.

This paper presents the analysis results obtained through SPOT1/2, ERS1, focused on thermal behaviour analysis.
