Radio navigation emulating GPS system
First Claim
1. A computer implemented method of emulating a conventional radio navigation system while using satellite based position information, the method comprising the computer implemented steps of:
- receiving an identifier associated with a conventional navaid;
retrieving coordinates corresponding to a location of the conventional navaid;
generating satellite based position information for an aircraft;
generating navigation information for the aircraft using the location of the conventional navaid and the satellite based position information for the aircraft; and
driving a display of a conventional radio navigation device by using the navigation information.

Abstract
The present invention provides a radio navigation emulating GPS device. In one embodiment, the radio navigation emulating GPS device receives an identifier associated with a conventional radio navaid. The present radio navigation emulating GPS device then retrieves latitude and longitude information corresponding to the received conventional radio navaid from a database. A satellite based position information system generates position information for the aircraft on which the present radio navigation emulating GPS device is disposed. The present radio navigation emulating GPS device then generates navigation information for the aircraft using the retrieved latitude and longitude information and the satellite based position information for the aircraft. The present radio navigation emulating GPS device then presents the navigation information in a manner which emulates the presentation of navigation information generated by a conventional radio navigation device. The entire emulation process is transparent to the user of the present radio navigation emulating GPS device.
