Abstract

The invention discloses a positioning method, device and system, wherein the method includes: calculating and obtaining the current positioning performance parameters of the GPS / MARG combined positioning system; if the positioning performance parameters meet the preset conditions, then starting Wi-Fi / MARG The combined positioning system performs positioning; the position information of the moving target is calculated according to the positioning results obtained by the GPS / MARG combined positioning system and the results obtained by the Wi-Fi / MARG combined positioning system. The present invention solves the technical problem that the positioning accuracy of moving targets is low in some environments caused by using GPS / MARG combined positioning system or Wi-Fi / MARG combined positioning system alone in the prior art, and achieves improved The technical effect of the positioning accuracy of the positioning system in various environments expands the scope of use of the positioning system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a positioning method, device and system. Background technique [0002] Currently, the Global Positioning System (Global Position System, GPS for short) is a positioning system widely used in smart terminals. In an open area, GPS can obtain relatively good positioning performance. However, in an urban area full of tall buildings or in a completely blocked indoor environment, the GPS positioning performance will deteriorate sharply or even fail to perform positioning. Wireless Fidelity (Wi-Fi) positioning technology has good positioning performance in urban and indoor environments, and can effectively make up for the deficiency of GPS positioning technology. However, in the wireless access point (Access Point, referred to as AP ) does not cover the area, because the lack of AP often leads to Wi-Fi positioning failure. The MARG sensor (a sensor combination based on a three-axis g...
