摘　　要：受主动段振动、在轨力热变形等因素影响,星载相对测量设备的测量坐标系相对于设备基准坐标系会产生一定偏移,引入测量误差,从而影响卫星的相对导航精度。为解决该问题,提出了一种基于全球卫星导航系统(global navigation satellite system,GNSS)差分定位数据的星载相对测量设备在轨标定方法,通过分析确定了影响其在轨标定精度的主要因素和其可达到的在轨标定精度水平,并结合在轨数据验证了该方法的正确性和有效性。Under the influences such as vibration in boost-phase and mechanical and thermal deformation on-orbit,the measuring coordinate system of space-borne relative measuring equipment will have a certain deviation from its reference coordinate system.The measurement error will be introduced,which will affect the relative navigation accuracy of the satellite.To solve the problem,an on-orbit calibration method for space-borne relative measuring equipment based on global navigation satellite system(GNSS)differential positioning data was presented.According to analysis,the main error terms affecting the calibration accuracy and the achievable calibration accuracy level were obtained.The correctness and effectiveness of the method were verified by on-orbit data.
