Abstract

The embodiments of the present invention are applicable to the field of positioning technology, and provide a positioning solution method, device and satellite navigation receiver. The method includes: receiving a satellite navigation positioning signal; calculating a floating point solution of the satellite navigation positioning signal; identifying Whether the floating-point solution includes a QMBOC signal; if the floating-point solution does not include a QMBOC signal, a preset first weight value is used to filter and estimate the floating-point solution; if the floating-point solution includes For the QMBOC signal, a preset second weight value is used to filter and estimate the floating-point solution, and the preset second weight value is greater than the preset first weight value; As a result, a fixed solution for the positioning signal is calculated. In this embodiment, the characteristics of the QMBOC signal can be utilized to realize high-precision solution and improve the precision and accuracy of positioning.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a positioning solution method, a positioning solution device, a satellite navigation receiver and a computer-readable storage medium. Background technique [0002] BeiDou Navigation Satellite System (BDS) is a global satellite navigation system developed by my country. The Beidou satellite navigation system consists of three parts: the space segment, the ground segment and the user segment. It can provide high-precision and highly reliable positioning, navigation, and timing services for all kinds of users in all weather and around the world. [0003] When using the Beidou satellite navigation system for positioning, the satellite navigation receiver can receive satellite signals and complete the positioning through a series of processing. Usually, the satellite navigation receiver consists of three parts: radio frequency reception, baseband processing and PVT ca...
