A GAMMA GUIDANCE SYSTEM FOR HELICOPTER FLIGHT-FORMATION CONTROL

Abstract

Preliminary studies confirm the feasibility of using gamma radiation as the sensing signal for an all-weather, short-range, stationkeeping, formation-control system for helicopters. This report discusses three methods investigated for determining range, aziinuth, and elevation. The eclipse method, which uses the difference signal between an unshielded and a shielded detector, was found to be capable of providing an accuracy of +/-10 percent in range and +/-1 degree in azimuth and elevation. It is racommended tbat expanded effort be directed toward the development of such a gamma guidance system.
