Problems solved by technology

However, due to the influence of error sources such as the ionosphere and troposphere during the transmission of the signal, the determination of the satellite's position information is inaccurate, which in turn leads to the inaccuracy of the satellite's autonomous orbit determination.

Abstract

The embodiment of the invention provides a satellite autonomous orbit determination method, device and equipment and a computer storage medium. The satellite autonomous orbit determination method based on the Beidou navigation system is applied to a target satellite, and comprises the following steps: determining first position information of the target satellite based on a micro inertial measurement unit (MIMU) in the target satellite; receiving first differential data corresponding to the first position information sent by the Beidou navigation system based on a satellite-borne Beidou receiver in the target satellite, wherein the first differential data is determined by the Beidou navigation system according to the first position information and a preset mapping relationship, and the mapping relationship is a mapping relationship between the position information and the differential data; resolving the first position information by using the first differential data to obtain second position information; and determining a satellite orbit to which the target satellite belongs based on the second position information. According to the satellite autonomous orbit determination method,device and equipment and the computer storage medium, satellite autonomous orbit determination can be carried out more accurately.

Description

technical field [0001] The invention belongs to the technical field of satellite autonomous orbit determination, and in particular relates to a satellite autonomous orbit determination method, device, equipment and computer storage medium based on the Beidou navigation system. Background technique [0002] Satellite autonomous orbit determination refers to the ability to independently determine the satellite orbit to which a satellite belongs without relying on the measurement and control of ground personnel. Before determining the satellite orbit to which the satellite belongs, the position information of the satellite needs to be determined first. [0003] At present, in the related art, the position information of the satellite is determined by sending a signal to the ground center, and then the ground center determines the position information of the satellite based on the signal. However, due to the influence of error sources such as the ionosphere and troposphere duri...
