Mutual geo-localization method for global positioning system receiver terminals, involves sending global positioning system coordinates, and receiving coordinates of participants authorized to know terminal position by terminal

摘要

The method involves activating a terminal by a user, and receiving an access message comprising an identifier of the user by a mainframe computer. Global positioning system coordinates are sent by the terminal, and coordinates of participants authorized to know a position of the terminal are received by the terminal via a telecommunication network. Messages pertaining to the position of terminal are received and retransmitted by the computer. The messages are exchanged directly between the terminal and another terminal.
