METHOD AND DEVICE FOR CORRECTING THE THERMOELASTIC EFFECTS NOTABLY FOR A SPACE TELESCOPE AND TELESCOPE COMPRISING SUCH A DEVICE

摘要

A method of correcting thermoelastic effects on the performance parameters of a telescope mounted on a space satellite includes a pre-model 26 of fluctuations in thermoelastic effects at orbital scale and programming data of a space satellite prior to the flight of the satellite. A first step 401 of a priori determination of the correction of thermoelastic effects by using an algorithm 25 for determining the correction delivered by; And a second step 403 carried out in flight, establishing control messages of the correction means 30 for correcting the performance parameters of the telescope 1 based on the a priori determined correction.
