Abstract

The stabilization and tracking issue was studied for SOTM, and the low cost M&C system applied "open loop stabilization, closed loop tracking and error correcting" was put forward based on the analysis for influencing factors on beam attitude control. The method using dynamic inclinometer correcting gyro error based on open loop control was brought forward, in closed loop control, the pointing error was derived from satellite tracking information, and the control structure using tracking information was built, the computer simulation indicates that this method could correct gyro low frequency error effectively.
