Problems solved by technology

The servers involved include the atomic clock server and the ephemeris data server. Most mobile phone users do not know how to choose a server, so the mobile phone positioning uses the default server. The communication time and communication quality are not guaranteed, resulting in the situation that the location cannot be located or the location is not accurate for a long time

Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0018] GPS positioning method of the present invention, as figure 1 shown, including steps:

[0019] Step S101, receiving a GPS positioning request;

[0020] Step S102, performing a network packet loss test on each candidate server related to GPS;

[0021] Step S103 , selecting the server with the best test result of the network packet loss test as the server used for GPS positioning in response to the GPS positioning request.

[0022] The alternative servers include the following three types of servers:

[0023] NTP_SERVER: Atomic clock server to obtain accurate...

Abstract

The invention discloses a GPS (Global Position System) position method and device. The speed and the accuracy rate of GPS position are increased by optimizing the communication speed between a mobile phone and a relevant GPS server. Particularly, network packet loss of multiple servers is tested; the server with an optimal test result is selected as the server for the current position operation, so that the situation of a poor position effect caused by the inappropriate server is avoided; and the method and the device are automatic without manual setting of a user.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a GPS positioning method and device. Background technique [0002] With the development of positioning and navigation, especially mobile phone positioning and navigation, people have higher and higher requirements for GPS positioning accuracy and positioning speed. Among them, the accuracy and speed of GPS positioning are restricted by the accuracy of time and the speed of communication between satellites, mobile phones and GPS servers. It is almost unrealistic for the device to determine in seconds. It takes at least 5 seconds to lock a satellite, and it generally takes about 20 seconds to communicate with a satellite one-way. If the device itself carries an atomic clock, the communication time between the device and the atomic clock server will be saved, and the positioning accuracy and speed will be greatly improved. But it is not yet possible to carry an ...
