Abstract

The invention relates to a calibration method, equipment and system for a space target measurement mechanism. The calibration method for the space target measurement mechanism comprises the followingsteps: acquiring a mechanism rotation angle of the mechanism by an angle transducer; respectively acquiring a star sensor attitude and a load camera attitude in preset time; acquiring a rotation angleerror of the mechanism according to the acquired star sensor attitude and load camera attitude; calibrating the mechanism according to the acquired rotation angle error. According to the calibrationmethod, equipment and system provided by the invention, by virtue of cooperative operations of the star sensor and the load camera, accurate calibration of the space target measurement mechanism is realized. Moreover, extra hardware does not need to be increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of space calibration, in particular to a calibration method, calibration equipment and a calibration system of a space target measurement mechanism. Background technique [0002] At present, space target measurement is an important part of space missions. In recent years, the demand for high stability, close tracking and alignment in my country has become increasingly urgent. With the continuous improvement of mission requirements for space target measurement, the requirements for the accuracy of payload cameras are getting higher and higher. The star sensor has the advantages of high precision, fast response, high reliability and long life, and has become an important part of satellite attitude determination. Using the star sensor and the payload camera to complete the initial optical axis calibration and alignment of the measurement task can achieve Very good effect. [0003] According to the calibratio...
