lnterferometric Flight Inspection Systems: Development and Flight Test Results

D. Stratton

Abstract:	New flight inspection ryrtemr from Parker Gull UIC simple but very accurate poritioning. The new systems ratisfy unique flight inspection requirements using the Global Positioning Syrtem (GPS) a8 a source for interferometry. An airborne inspection conrole with an autonomous ground unit analyze8 a full range of radk navigation syrtemr automatkally hi flight. Parker Gull validated this new technology in flight tertr with Ohio University Avionks Engineering Center. Results of over fifty approaches prove the ryrtem achieves Category III capability on a par with automatic 8yrten.u ured by the United Stati Federal Aviation Administration (FAA). With procedure8 and software designed especially for flight inspection, robust accuracy is attained even when satellite geometry and 8upporthIg measurements are rub- optimal This latert technology ha8 been integrated with systems and software matured over two decades of FM support. Gull is producing the first of these system8 for FM certification of GPS helicopter approaches throughout the United States.
