Orbit Forecasting, Tracking and Pointing System Based on High altitude Aircraft Laser Communication

The aircraft's orbit was forecasted based on the initial position and speed of the aircraft. The simulation confirmed the accuracy of the track forecasting algorithm and calculated the pointing angle reading error based on the designed pointing system. During the experiments, the variance between the forecasted algorithm and actual orbit was obtained, subsequently converting the results to the local coordinate system and computing the pointing error. Finally, the pointing error of the system in the orbit forecast algorithm was derived through the consideration of the optical mount error and platform vibration.
