Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] The satellite navigation system in this embodiment includes but is not limited to BD satellite navigation system, GPS system, Glonass satellite navigation system, Galileo satellite navigation system and the like. Each satellite navigation system consists of several satellites. In this embodiment, the satellites whose receivers can receive satellite signals are called positioning satellites. Take the BD satellite navigation system as an example...

Abstract

A receiver for a multi-mode navigation system includes a base band unit and a calculation unit. The base band unit is configured for allocating resources to positioning satellites in each of one or more navigation system, and tracking the positioning satellites with the allocated resources to obtain satellite information of each of the positioning satellites. The satellite information includes one or more of pseudo-ranges, position coordinates, velocity information, and frequency information of the positioning satellites. The calculation unit is configured for receiving the satellite information from the base band unit, evaluating the positioning satellites in each navigation system, and determining a positioning parameter of the receiver. Determination of the positioning parameter includes calculating a position and a velocity of the receiver based on the satellite information according to a least square algorithm.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a receiver and a satellite positioning and speed measuring method. Background technique [0002] The Beidou (BD for short) satellite navigation system is a global satellite navigation system independently developed and operated independently by China. ) satellite navigation system, the European Union's Galileo (Galileo) satellite navigation system and known as the world's four major satellite navigation systems. [0003] Existing receivers can only support one of the above-mentioned satellite navigation systems, that is, they can only perform positioning based on the received satellite signals of the same satellite navigation system, and receivers that can support two or more satellite navigation systems have not yet been realized. . Contents of the invention [0004] The embodiment of the present invention provides a receiver and satellite positioning and speed ...
