Paper Abstract

This paper presents a study of an omnidirectional locating sensor for guiding mobile platforms. Using a reference laser source, it is possible to use this sensor for attitude determination of a mobile platform. A specific sensor has been designed for this application and allows us to cover an azimuth of 360 degrees without any scanning or mechanical systems. The sensor head is composed of a set of large area silicon photodiodes, characterized by a specific angular gain and producing signals that are dependent on the angular position of the reference source. The locating technique produces an estimate of the angular position of the reference beam in terms of azimuth and elevation, with a resolution better than one degree, for a set of nine detectors. Providing proper positioning of the reference beam, it is possible to guide a platform avoiding any physical link along any trajectory and over great distances. The analysis of accuracy and system performance is also presented.
