Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a ground comprehensive test system and method for satellite data transmission. Background technique [0002] The satellite high-speed data transmission system is mainly responsible for the transmission of payload data between the satellite and the ground station. Since the satellite high-speed data transmission system is the only way for the satellite in orbit to exchange data with the ground, it must have a high degree of reliability. Therefore, before the satellite is launched, it is necessary to rely on the ground test system to conduct strict tests on the satellite high-speed data transmission system. The test indicators of satellite high-speed data transmission system are diverse and the test process is complicated, so ground test equipment is required to meet differentiated test requirements. In addition, with the improvement of on-board data processing capabilities of ...
