Method and system for using a database and GPS position data to generate bearing data
First Claim
1. A system for providing a bearing signifying a deviation of a vehicle from a desired course, the system comprising:
- a database storing transmitter position information identifying a position of a transmitter transmitting bearing signals to the vehicle;
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,wherein said controller is further configured to;
identify when the vehicle is in a VOR cone of confusion extending from the transmitter based on the transmitter position information and vehicle position information; and
calculate an estimated deviation representing a deviation from a desired course to the transmitter using the bearing from the vehicle to the transmitter.

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.
