Abstract

This invention provides an on-orbit calibration system and method for the performance of an inter-module electromagnetic adsorption device on a dual-supersonic satellite. The system includes an inter-module electromagnetic adsorption device requiring performance calibration and an inter-module relative position measurement device for calibration. The inter-module relative position measurement employs non-contact measurement technology using laser displacement sensors and eddy current displacement sensors. Using mass characteristic test data of the two satellite modules and on-orbit inter-module relative position measurement data as input, the performance calibration data of the inter-module electromagnetic adsorption device is obtained through solving dynamic equations. This invention, technically optimized for dual-supersonic satellite applications, offers high reliability and, by employing a non-contact measurement method, eliminates additional interference. Through the effective application of this invention, the performance calibration data of the inter-module electromagnetic adsorption device can be introduced into the dual-supersonic satellite control system, effectively improving the accuracy and level of dual-supersonic satellite magnetic levitation control.
