Star sensor thermal mode study in flight

摘要

The results of the mathematical simulation of the star sensor thermal mode are compared with the ground test data and with the flight star sensor thermal mode data for mission.The comparison allows the following:1 to predict the star sensor thermal mode by the limited data,received from the satellite;during orbital flight;2 to confirm a possibility of the star sensor lens contamination condition appearance (dust particles precipitation at the lens first optical surface);3 to avoid the optic degradation the recommendations are given.
