A hybrid positioning method for mobile trends

Abstract

The invention relates to a movement trend hybrid positioning method, comprising the following steps: a mobile device calculates base station related information and WIFI hotspot information through data acquisition and operation; the mobile device transmits base station data to a server, the server performs signal difference calculation to obtain longitude and latitude of the mobile device; when the mobile device contains a GSM module, the server performs differential position calculation for differential signal values of multiple base station signals; when the mobile device is in a moving state, the server performs movement trend analysis on the data transmitted by the base station to obtain longitude and latitude of the mobile device; when the mobile device has no communication signal and no GPS signal, the server adopts WIFI signal differential positioning; and when the mobile device simultaneously has a GPS communication module and a WIFI communication module, the server automatically adopts an energy consumption algorithm. The method provided by the invention effectively solves a problem of precision of positioning in different geographical environment and different hardware environment, effectively promotes battery endurance of the device and greatly reduces cost of hardware products.

Description

technical field [0001] The invention belongs to the technical field of mobile positioning, and in particular relates to a mobile trend hybrid positioning method. Background technique [0002] In recent years, mobile positioning technology has received more and more attention, which has promoted the research on mobile positioning technology and the development of ranging technology. The basic principle of mobile positioning technology is: moving targets pass through multiple fixed base stations with known coordinate positions (ground or air) to interact, obtain the corresponding measurement parameters, and use appropriate processing methods to obtain the position of the moving target in space. Measurement parameters generally include the transmission time, amplitude, phase and angle of arrival of radio waves.

Problems solved by technology

[0003] Traditional satellite-based GPS positioning has advantages in its positioning accuracy, but there are limitations of geographical conditions:

[0004] 1. The positioning cannot be completed when the satellite signal cannot reach more than three satellites;

[0005] 2. When the positioning device is indoors or the signal cannot reach, the positioning cannot be performed;

[0006] 3. At the beginning, the GPS module needs to transmit signals with the satellite in real time, and the energy consumption is relatively large;

[0007] 4. The use of GPS and other satellite positioning models requires an increase in hardware costs

[0009] 1. The inaccuracy of positioning accuracy (2000 meters range error);

[0010] 2. Precise positioning cannot be achieved when the object is moving
