Satellite positioning method and device for high-altitude equipment, computer device and storage medium

Abstract

The invention relates to a satellite positioning method and device for high-altitude equipment, a computer device and a storage medium. The method comprises the following steps: acquiring equipment observation data of high-altitude equipment to be positioned; determining the general position of the high-altitude equipment according to the equipment observation data; determining more than one target reference station arranged on the ground according to the general position, and obtaining reference station observation data corresponding to each target reference station; determining common-view satellites respectively corresponding to the high-altitude equipment and each target reference station according to the equipment observation data and the reference station observation data; wherein the common-view satellite is a satellite jointly observed by high-altitude equipment and a target reference station; determining common-view satellite observation data corresponding to the common-view satellites from the equipment observation data and the reference station observation data, and obtaining satellite positioning data of the high-altitude equipment according to the common-view satelliteobservation data. By adopting the method, the satellite positioning precision of high-altitude equipment can be improved.

Description

technical field [0001] The present application relates to the technical field of satellite positioning, in particular to a satellite positioning method, device, computer equipment and storage medium for high-altitude equipment. Background technique [0002] Satellite positioning is a technology that uses satellites to accurately locate something. Specifically, by using two-way communication between satellites and receivers to determine the position of the receiver, it can provide users with accurate location coordinates and related attributes in real time around the world. feature. At present, the realization of satellite positioning includes Global Positioning System (Global Positioning System, GPS), Global Navigation Satellite System (Global Navigation Satellite System, GNSS), BeiDou Navigation Satellite System (BeiDou Navigation Satellite System, BDS), etc. Satellite positioning technology is widely used in vehicle navigation, emergency response, atmospheric physical obs...

AI Technical Summary

Problems solved by technology

[0003] However, in the application of atmospheric physical observation for satellite positioning of high-altitude equipment, such as navigational radiosondes, the high-altitude observation environment of the high-altitude equipment is quite different from the traditional ground observation environment, and the positioning error is large, resulting in the satellite positioning of the high-altitude equipment. Positioning accuracy is low
