Error calibration method and device for distance measuring system of GEO satellite ground measurement and control station

The invention provides a GEO satellite ground measurement and control station distance measurement system error calibration method and device, and relates to the technical field of satellite measurement and control, and the method comprises the steps: obtaining a plurality of groups of theoretical distance measurement and actual distance measurement corresponding to a target ground measurement and control station on a plurality of standard ephemeris points of a GEO satellite, so as to calculate a distance measurement residual error mean value of the target ground measurement and control station; determining the relative system error of the target ground measurement and control station based on the distance measurement residual mean value of the target ground measurement and control station and the minimum distance measurement residual mean value of the plurality of ground measurement and control stations; taking the distance measurement errors as respective distance measurement error input, and performing pre
