1. A relative vehicle positioning system for a first vehicle comprising:
- a GPS antenna adapted to receive satellite signals generated in response to relative vehicle positioning and generate therefrom a GPS signal;
a first Bluetooth radio coupled to the first vehicle and adapted to exchange bearing information with a second vehicle and generate therefrom a PVT signal;
a second Bluetooth radio coupled to the first vehicle and adapted to synchronize the first vehicle with said second vehicle; and
a GPS unit comprising a controller adapted to receive said GPS signal and said PVT signal and generate therefrom, a GPS-Bluetooth relative position signal.

Abstract
A relative vehicle positioning system for a vehicle includes a GPS antenna adapted to receive satellite signals generated in response to relative vehicle positioning and generate therefrom a GPS signal. A Bluetooth radio is adapted to exchange bearing information with a second vehicle and generate therefrom a PVT signal. A GPS unit including a controller is adapted to receive the GPS signal and the PVT signal, the GPS unit is further adapted to generate therefrom a GPS-Bluetooth relative position signal.
