Abstract

The embodiment of the invention is applicable to the technical field of positioning, and provides a positioning calculation method and device and a 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 comprises a QMBOC signal or not; if the floating point solution does not include the QMBOC signal, performing filtering estimation on the floating point solution by adopting a preset first weight value; if the floating point solution comprises the QMBOC signal, adopting a preset second weight value to carry out filtering estimation on the floating point solution, and the preset second weight value is larger than the preset first weight value; and calculating a fixed solution of the positioning signal according to a result of the filtering estimation. According to the embodiment, the characteristics of the QMBOC signals can be utilized, high-precision calculation is achieved, and the positioning precision and accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a positioning calculation method, a positioning calculation device, a satellite navigation receiver and a computer-readable storage medium. Background technique [0002] BeiDou Navigation Satellite System (BDS for short) is a global satellite navigation system independently 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, high-reliability positioning, navigation, and timing services for various users around the clock and around the world. [0003] When the Beidou satellite navigation system is used for positioning, the satellite signal can be received by the satellite navigation receiver and undergo a series of processing to complete the positioning. Usually, a satellite navigation receiver is composed of three parts: radio frequency ...
