Perspective Navigation System.

Abstract

This report describes a perspective navigation system which employs a K-band interferometer mounted on an aircraft or similar platform. The interferometer measures angle of arrival of signals from an array of six ground mounted transmitters. The angle measurement data is processed by a least-squares algorithm which computes the position and orientation of the ground array relative to the interferometer coordinate system. A perspective display of the ground array is generated based on the derived position/orientation data. The system is designed to operate at extremely low elevation angles where multipath is the dominant problem. An experimental effort was carried out to demonstrate the techniques. The results obtained are included in the report. System errors were shown to be small enough to allow aircraft landing based on the perspective display data under worst-case conditions. (Author)
