High-precision satellite positioning device and method based on triangular receiver array

Abstract

The present invention relates to a high-precision satellite positioning device on the basis of a triangle receiver array and a positioning method thereof. The device provided by the invention comprises a triangle receiver array formed by three single point satellite positioning receivers, and the antenna phase center of each single point satellite positioning receiver is located on each peak of the triangle receiver array; and each single point satellite positioning receiver includes one MCU and one receiver connected with the MCU, and MCUs are connected in parallel and are connected with a processor module. According to the invention, three single point satellite positioning receivers are arranged in a triangle mode to form a receiver array circuit, so that three-part errors of single point satellite positioning receivers may be furthest eliminated, and satellite positioning signals issued by a satellite positioning system are directly employed and processed to substantially improve the positioning precision; and moreover, the high-precision satellite positioning device on the basis of a triangle receiver array and the positioning method thereof are reasonable in design, high in precision, low in cost, convenient for usage and the like, and is able to be applied and promoted on a large scale in the field of the high-precision real-time satellite positioning navigation.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation and positioning, in particular to a high-precision satellite positioning device and method based on a triangular receiver array without relying on a reference station. Background technique [0002] Satellite positioning and navigation systems mainly include GPS, Beidou, GLONASS, Galileo, etc. With the rapid development of satellite positioning technology, people's demand for fast and high-precision location information is becoming increasingly strong. At present, the application range of high-precision real-time satellite positioning and navigation is becoming wider and wider, requiring the positioning accuracy of user receivers to reach decimeter or even centimeter level. [0003] Single-point satellite positioning receiver technology has been very mature. According to known principles, satellite positioning is realized by using observations such as pseudorange, ephemeris, and satel...

AI Technical Summary

Problems solved by technology

However, the cost of building and using the reference station, data link and user receiver is very high, and the operation is cumbersome. In addition, the biggest problem encountered in the application is that the effective distance and range of the correction data of the reference station are very limited. These defects hinder Large-scale application and promotion of high-precision real-time satellite positioning and navigation
