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.
