Description
technical field [0001] The invention relates to the field of satellite research and development and the application field of calibration satellites, in particular to a calibration data broadcasting device. Background technique [0002] The calibration satellite mainly provides the motion state reference for the ground measurement and control equipment, and is used to calibrate the performance of the ground measurement and control equipment. The calibration satellite application mode includes two application modes: center calibration and independent calibration. [0003] In the center calibration mode, the ground measurement and control equipment measures the satellite through the measurement link when the calibration satellite transits, obtains the satellite motion state, and sends the measured motion state data to the ground application system through the ground network; after the event, the satellite passes through the data. The transmission link transmits its own data to...
