COOPERATIVE GLOBAL POSITIONING SYSTEM (GPS) PROCESSING BY MOBILE TERMINALS THAT COMMUNICATE VIA AN AD HOC WIRELESS NETWORK

摘要

The position of a given mobile terminal is determined by communicating satellite positioning system information between the given mobile terminal and at least one other mobile terminal over a short-range, ad hoc wireless network, such as a Bluetooth network, to cooperatively determine the position of the given mobile terminal by the given mobile terminal and the at least one other mobile terminal that communicate over the short-range, ad hoc wireless network. Satellite positioning system information may communicated by distributing processing of the satellite positioning information, by distributing receiving of satellite positioning system information from a satellite, by communicating assistance data and/or by synchronizing timing of satellite positioning information, between the given mobile terminal and the at least one other terminal over the short-range, ad hoc wireless network.
