The payload system level verification test is very important in satellite development in order to verify the satellite system final performance. The payload radiation performance test in planar near field is described, as well as the payload with different uplink and downlink operating frequencies. In planar near field, the feed array is tested with satellite payload system, the feed array tested data could be imported to GRASP reflector’s simulated software, and the second radiation pattern is compared with the designed results, to verify the satellite system operating performance. The second radiation pattern is in accordance with the designed results, and the final payload performance verification is successfully realized. This paper presents the satellite system level test methods and the solutions for many difficulties and problems in transfered frequency radiation pattern test.
