1. A vehicle positioning system comprising:
- a receiver configured to receive information representative of signals transmitted by one or more other vehicles, wherein each signal comprises data relating to the position of the associated other vehicle;
a processor configured to process the data relating to the position of each other vehicle to determine an estimate of the position of the vehicle positioning system; and
a satellite positioning system configured to receive information representative of received satellite signals;
wherein the processor is further configured to;
determine a first location of the vehicle positioning system in accordance with the received satellite signals;
compare the first location of the vehicle positioning system with the estimate of the position of the vehicle positioning system; and
if the difference between the first location and the estimate of the position of the vehicle positioning system is greater than a threshold value, then use the estimate of the position of the vehicle positioning system as the location of the vehicle positioning system instead of using the satellite positioning system.

12. A method for determining the position of a vehicle, comprising:
-
receiving information representative of signals transmitted by one or more other vehicles, wherein each signal comprises data relating to the position of the associated other vehicle; determining an estimate of the position of the vehicle by processing the data relating to the position of each other vehicle; determine a first location of the vehicle positioning system in accordance with a set of received satellite signals from a satellite positioning system; compare the first location of the vehicle positioning system with the estimate of the position of the vehicle positioning system; and if the difference between the first location and the estimate of the position of the vehicle positioning system is greater than a threshold value, then use the estimate of the position of the vehicle positioning system as the location of the vehicle positioning system instead of using the satellite positioning system. - View Dependent Claims (13)

15. A vehicle positioning system comprising:
-
a receiver configured to receive information representative of signals transmitted by one or more other vehicles, wherein said other vehicles are configured to be in current communication with a satellite positioning system and wherein each signal comprises data relating to the position of the associated other vehicles; a processor configured to process the data relating to the position of each other vehicle to determine an estimate of the position of the vehicle positioning system; and wherein the satellite positioning system configured to receive information representative of received satellite signals; wherein the processor is further configured to; determine a first location of the vehicle positioning system in accordance with the received satellite signals; compare the first location of the vehicle positioning system with the estimate of the position of the vehicle positioning system; and if the difference between the first location and the estimate of the position of the vehicle positioning system is greater than a threshold value, then use the estimate of the position of the vehicle positioning system as the location of the vehicle positioning system instead of using the satellite positioning system.
