Abstract

The invention provides a positioning method and device. The positioning method comprises the steps of acquiring satellite longitude and latitude position information and satellite parameter information; according to the satellite longitude and latitude position information and the satellite parameter information, determining a satellite positioning system meeting preset positioning system requirements; selecting an auxiliary positioning signal suitable for the satellite positioning system from auxiliary positioning signals of the auxiliary positioning system according to the satellite longitude and latitude position information and the satellite parameter information; and performing positioning calculation according to the selected auxiliary positioning signal and the satellite positioningsystem to obtain a positioning result. Through adoption of the technical scheme, the satellite positioning system and the auxiliary positioning signal can supplement each other to fit the actual situation of an environment where the terminal equipment is located, interference and mutual exclusion among various signals caused by randomly selecting various signals can be effectively avoided, and the improvement of the positioning precision is facilitated.

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...
