Abstract

A mixed positioning method includes starting up normal assisting - positioning process first by mixed positioning terminal when positioning request sent from user is received, sending request of positioning assistance data and radio network cell identification number to server, catching satellite signal and measuring pseudo-distance by GPS signal receiver after assistance data is obtained, sending measured result and radio network cell identification number again to server then carrying out treatment on data by server. The mixed positioning terminal used for realizing said method is also disclosed.

Description

technical field [0001] The present invention relates to technical fields such as wireless communication, computer network communication, electronic and electrical design, satellite positioning, etc., and more mainly relates to a hybrid positioning method integrating A-GPS satellite positioning, wireless mobile communication network and radio transmission directional technology. Background technique [0002] The current GPS (Global Positioning System) positioning mainly uses the pseudo-range measurement method, which is based on the following formula: [0003] ρ 1 = ( x 1 - x u ...
