Abstract

The present application proposes a positioning method and device. The positioning method includes: obtaining satellite longitude and latitude position information and satellite parameter information; according to the satellite longitude and latitude position information and satellite parameter information, confirming the satellite positioning system that meets the preset positioning system requirements; According to the satellite longitude and latitude position information and satellite parameter information, select an auxiliary positioning signal suitable for the satellite positioning system from the auxiliary positioning signals of the auxiliary positioning system; perform positioning calculation according to the selected auxiliary positioning signal and the satellite positioning system , to get the positioning result. The adoption of the above technical solution can make the satellite positioning system and the auxiliary positioning signal complement each other, suit the actual environment of the terminal equipment, and can effectively avoid interference and mutual exclusion between multiple signals caused by random selection of multiple signals, which is conducive to improving positioning accuracy.

Description

technical field [0001] The present application relates to the technical field of satellite positioning, in particular to a positioning method and device. Background technique [0002] With the popularity of handheld terminals and the improvement of mobile communication networks, the satellite positioning function has become a very popular product function on handheld terminals. Various satellite positioning systems, such as Beidou, GPS, GLONASS, etc., provide relatively complete positioning signal support for terminal positioning. [0003] In order to improve the positioning accuracy of the positioning system, the industry has configured an auxiliary positioning system for the satellite positioning system to realize comprehensive satellite positioning based on the satellite positioning system and supplemented by the auxiliary positioning system. The satellite signal of the auxiliary positioning system is used for satellite positioning in order to improve the positioning acc...
