Flight Experiment Results for Aircraft Positioning with Carrier Phases

Masaaki Murata, Toshiaki Tsujii, and Masatoshi Harigae

Abstract:	A flight experiment was conducted for high precision aircraft positioning with the Global Positioning System (GPS). The Trimble 4000SSE receivers and the Dornier Do-228, an experimental research aircraft of National Aerospace Laboratory (NAL), were used. GPS carrier and code phase observations collected were analyzed to determine the aircraft position, with emphasis on the modeling of the tropospheric propagation delay. The cm-level accuracy of the carrier phase positioning was demonstrated by checking the observation residuals, the trajectory mismatch and comparison of forward and backward processing. This highly accurate solution was then used to assess the accuracy achievable with carrier smoothed code solution, and the agreement with the laser-tracked profile. Finally, some experiences for carrier phase ambiguity resolution on the fly are presented.
