METHOD AND SYSTEM FOR USING A DATABASE AND GPS POSITION DATA TO GENERATE BEARING DATA
First Claim
1. A method for providing a bearing from a vehicle to a transmitting station, said method comprising:
- accessing a database to obtain transmitter position information for the transmitting station;
obtaining vehicle position information based on a GPS signal;
generating the bearing from the vehicle to the transmitting station utilizing the transmitter position information and the vehicle position information;
identifying when the vehicle is in a VOR cone of confusion extending from the transmitting station based on the transmitter position information and the vehicle position information; and
calculating an estimated deviation representing a deviation from a desired course to the transmitting station using the bearing from the vehicle to the transmitting station.

Abstract
A method and system for providing a bearing from a vehicle to a transmitting station are described. The method includes accessing a database to obtain transmitter position information for the transmitter, obtaining vehicle position information based on a GPS signal, and generating the bearing from the vehicle to the station utilizing the transmitter position information and the vehicle position information. The system includes a database storing transmitter position information identifying a position of the transmitter, a GPS receiver obtaining vehicle position information identifying a current position of the vehicle based on a GPS signal, and a controller generating a bearing from the vehicle to the transmitter utilizing the transmitter position information and the vehicle position information.
