Abstract: |
Tracking precision of servo system is a key performance indicator to determine the quality of satellite communica⁃
tion. The antenna installation error, angle sensor error, different combinations of inertial navigation system are analyzed.
The “level⁃drop” method is proposed and effective test and evaluation of tracking precision are realized. The method has
great reference value, and can be used in similar flight test subjects. |
