Satellite optical communication ground testing platform analysis

In the isolation testing platform, vibration spectrum is tested, The course of test, result from atmospheric disturbances and optical aberration, That studies typical tracking facula Center of gravity Algorithm and summarizes reason of the algorithm precision, Result in frequency-field facula algorithm. Experiment performance results from the effect of background and anomaly facula and so on. Integrates from high precision and center of gravity algorithm, frequency-field optical communication tracking method is designed. The method is immunity to the halation, optical aberration and optical communication link. The range of testing platform vibration less than two scalar NASDA satellite platform vibration, that is achievable the tracking test, and put forward optimization time segment.
