GPS navigation system and method thereof

A system and method of GPS navigation are used for guiding a group of mobile platforms. Through an initiation negotiation process, primarily platforms and the secondary platforms are selected from the mobile platforms to form a peer-to-peer (P 2 P) network. Each of the secondary platforms are connected to one of the primarily platform to transfer communication data containing GPS data to the correspondingly connected primarily platform. Then each primarily platform collects the communication data received from the correspondingly connected secondary platforms, and exchange data with the other primarily platforms. Exchanged data are transmitted to every secondary platform; therefore every mobile platform receives GPS data of the others, thus the mobile platforms are guided based on the communication data containing the GPS data.
