Description

The main functions of the QV-band feed antenna are as follows: (1) Receive attitude control beam control information, control the antenna beam pointing, and cooperate with the attitude control system to complete the staring pointing to the ground gateway station; (2) Receive forward signals; (3) Radiate and output return signals; (4) Equipped with 2 sets of integrated transceiver antennas to support in-orbit relay use; (5) Support transceiver polarization reuse and shared transceiver antenna; (6) Support multi-channel signal transmission and reception via a single antenna. The antenna’s all operating modes are initiated and controlled by the GMS (Ground Mission System). Relevant control commands (sets) are injected into the satellite platform via the TT&C (Tracking, Telemetry and Command) link, and then processed by the satellite platform to complete the control of the payload, which is required to cooperate to implement the above control operations.
