AD-HOC differential GPS referencing using parked vehicles
First Claim
1. A method of determining a position of a moving vehicle comprising:
- detecting a global position by a global positioning device of at least one parked vehicle in a vicinity of the moving vehicle, the global position determined as a function of signals broadcast by a plurality of satellites;
determining errors associated with the broadcast signals;
determining a correction error that provides a solution for eliminating the errors associated with the broadcast signals;
transmitting the correction error to the moving vehicle;
applying the correction error to a received global positioning signal received by the moving vehicle;
determining a global position of the moving vehicle as a function of the correction error;
applying the determined global position of the moving vehicle in a vehicle application.

Abstract
A method of determining a position of a moving vehicle. A global position is detected by a global positioning device of at least one parked vehicle in a vicinity of the moving vehicle. The global position is determined as a function of signals broadcast by a plurality of satellites. Errors associated with the broadcast signals are determined. A correction error that provides a solution for eliminating the errors associated with the broadcast signals is determined. The correction error is transmitted to the moving vehicle. The correction error is applied to a received global positioning signal received by the moving vehicle. A global position of the moving vehicle is determined as a function of the correction error. The determined global position of the moving vehicle is applied in a vehicle application.
