Abstract
To solve the special requirements of the high orbit optical remote sensing-satellite for the thermal deformation of the platform, the thermal deformation test and measurement scheme of the satellite platform is designed. Through the comparative analysis of test results, the rationality of the thermal deformation design of the platform structure is verified. The results of thermal deformation measurement show that the maximum deformation of A camera mounting surface is 57.5', and the maximum deformation of B camera mounting surface points to 79.3', which can be used as the basis for thermal deformation prediction of satellite during the orbit operation.
