Description
The Inter-Satellite and Ground Communication Reflector Antenna (ISGC-RA) operates in the QV-band and provides the functions of inter-satellite communication beam transceiving, satellite-ground communication beam transceiving, and mechanical rotation of the antenna. The main tasks of the antenna assembly are as follows: After the satellite is successfully inserted into orbit, the antenna is released and deployed to the initial operating position via the hold-down and release mechanism (HDRM) in accordance with the satellite system requirements. The controller receives control commands such as pointing angles, drives the antenna to perform two-degree-of-freedom motion, and completes pointing and tracking tasks toward the designated area. In calibration mode, it can perform tracking scanning based on the feedback energy signals.
