ABSTRACT:
The system described herein uses distance information from aircraft to multiple ground stations of the TACAN, VORTAC, VOR/DME or DME type to determine position of the aircraft to a high degree of accuracy exceeding the normal capabilities of these types of equipment. The present system uses a scanning type DME unit which is rapidly sequenced to interrogate said multiple ground stations successively and determine distance thereto for all stations within range, and a computer to validate and process these distance measurements in sequence to provide an accurate computation and display of aircraft position and wind information.
