Embodiment Construction

[0010] The method of the present invention for improving the satellite search capability of a GPS receiver is designed to automatically reduce the positioning accuracy to ensure that the receiver is positioned in time when encountering environmental interference; and to automatically restore positioning accuracy when there is no environmental interference. High-precision mode positioning.

[0011] An embodiment of the present invention is to run a program on a GPS receiver with input and a mobile terminal that supports GPS data processing and GPS receiver parameter setting, and the program controls: read when the GPS receiver is in high-precision mode After the positioning data is invalid, modify the positioning accuracy setting parameters of the GPS receiver to make it work in the low-precision mode; after the GPS receiver is in the low-precision mode to read the positioning data is valid, modify the positioning accuracy setting parameters of the GPS receiver. Make it work in hig...

Abstract

The invention relates to a method for positioning using global positioning system (GPS) comprising, executing a program on the GPS receiver having the parameter configuration supporting the positioning accuracy and a mobile terminal supporting GPS data processing and GPS receiver parameter configuration which controls, when the read out positioning data is invalid in the high accuracy mode of the GPS, correcting the GPS receiver positioning accuracy configuration parameter, making it turn into low precision mode operation, when the read out positioning data is valid in the low accuracy mode of the GPS, correcting the GPS receiver positioning accuracy configuration parameter, making it turn into high precision mode operation.

Description

Technical field [0001] The present invention belongs to a method of positioning by using radio waves to determine the cooperation of two or more distances, especially a method of positioning using a global positioning system (GPS). Background technique [0002] In the supervision and management of mobile vehicles, using a vehicle-mounted mobile terminal with a global positioning system (GPS) is a brand new choice. It can provide positioning information such as the latitude, longitude, speed and direction of the vehicle to the dispatch center at any time. The dispatch center usually manages mobile vehicles by extracting the positioning information of the controlled vehicle (monitoring) according to a fixed monitoring cycle, receiving the positioning information (alarm) provided when the controlled vehicle is alarmed, and accepting the positioning information (positioning) provided by the controlled vehicle throughout the process. . The positioning accuracy (PDOP) value of the GPS ...
