Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, 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, not to limit the present invention.

[0021] Such as figure 1 As shown, the cooperative GPS receiver system in this embodiment includes N GPS receivers respectively located in multiple terminals that can be connected by short-distance communication, and the N GPS receivers can work together to complete GPS information search. As shown, each GPS receiver consists of the following components:

[0022] The short-distance communication module is used to form a cooperative GPS positioning wireless network with other N-1 GPS receivers within the communication range at the initial moment of the cold start of the GPS receiver; and other GPS p...

Abstract

The invention provides a quick starting method of a GPS (Global Position System) receiver and a cooperative GPS receiver system. The quick starting method comprises the following steps of: at the initial time of cold start, establishing a cooperative GPS positioning wireless network by a currently started GPS receiver and the other N-1 GPS receivers in a communication range of the currently started GPS receiver; assigning one of the N GPS receivers as a network main control machine; respectively assigning information search parameters for each GPS receiver by the network main control machine, respectively carrying out corresponding information search by each GPS receiver to report the research result to the network main control machine; gathering information by the network main control machine and then sending the gathered information to the GPS receiver in the current cold start; and entering a normal working state by the GPS receiver according to the gathered information. With the adoption of the quick starting method disclosed by the invention, the information searching time of the GPS receivers in a cold start process can be greatly reduced, so as to realize quick cold start.

Description

technical field [0001] The invention relates to the field of global satellite positioning and navigation systems, in particular to a quick start method for a GPS receiver and a coordinated GPS receiver system. Background technique [0002] A global satellite positioning and navigation system, such as the United States' National Positioning System (GPS), consists of a constellation of satellites (also known as Navstar satellites) that transmit GPS signals that can be used by a receiver to determine the location of the receiver. Location. Satellite orbits are arranged in multiple planes so that the signal can be received from at least four satellites at any location on Earth. [0003] With the gradual maturity of GPS receiver technology, there are more and more terminals with GPS receiver functions on the market, some of which use a separate GPS positioning module to achieve positioning, and some integrate the GPS positioning module into the main chip of the terminal positi...
