Ground calibration device and calibration method for in-orbit mass measurement instrument

Abstract

The invention discloses a ground calibration device for an in-orbit mass measurement instrument. The ground calibration device comprises a microgravity environment simulation device and a calibrationprocess state monitoring system. The microgravity environment simulation device comprises a high tower suspension mechanism and an adjustable horizontal workbench. The calibration process state monitoring system comprises a suspension rope tension monitoring module, a tested object deflection angle monitoring module and a tested object acceleration monitoring module. By aerial suspension for gravity counteraction, a microgravity environment is simulated on a water plane close to a suspension balance point; by the established calibration process state monitoring system for real-time monitoringof a calibration process, whether the calibration process meets set boundary conditions or not can be judged, and an in-orbit mass measurement instrument indicating value corresponding to the measurement process meeting the set boundary conditions is determined as a ground calibration effective value, so that a brand-new solution approach is provided for ground calibration of the in-orbit mass measurement instrument. The ground calibration device has advantages that effective calibration of the in-orbit mass measurement instrument in a ground environment is realized while calibration operationis standardized, and metrological guarantee is provided for equipment used in the special environment.
