Method for performing positioning processing on lunar exploration data by satellite

Abstract

The invention relates to a method for performing positioning processing on lunar exploration data by a satellite. The method comprises the steps of constructing a lunar exploration positioning coordinate conversion system according to positioning processing of the positioning processing method; acquiring exploration characteristic data of a sensor, and constructing initial observation vectors suitable for multiple types of sensor visual fields on positioning coordinates according to the exploration characteristic data of the sensor; acquiring sensor mounting parameters, satellite attitude data and satellite ephemeris data according to the initial observation vectors of the sensor, and converting the observation vectors of the sensor from a sensor coordinate system to a lunar center fixed coordinate system; processing the observation vectors of the server based on the lunar center fixed coordinate system to obtain an intersection between the sensor and the moon, thus obtaining exploration positioning data, wherein the exploration positioning data are lunar geodetic coordinates corresponding to an exploration position. According to the method for performing positioning processing on the lunar exploration data by the satellite, introduction of middle errors is alleviated, and the calculation precision is improved.
