AI Technical Summary
During satellite operation, it is difficult to accurately and stably point the satellite at the ground station with a laser. Existing technologies cannot effectively solve the problem of satellite attitude measurement and control.
By receiving forecast commands from the ground station, the system uses computer calculation cycles and prediction iterations to determine the optimal forecast time, accurately searches for the optimal light emission time, and calculates the three-axis attitude angles of the laser payload based on orbital parameters and the location of the ground station, then initiates attitude maneuvers to adjust the satellite's attitude.
It improves the laser pointing accuracy and computational efficiency of satellites to ground stations, solves practical problems in satellite on-orbit applications, and has high precision and engineering applicability.
