Satellite navigation for high precision aircraft navigation with emphasis on atmospheric effects

Investigations into very high precise aircraft position determination with the Global Positioning System are presented. After a short introduction into the GPS code and carrier wave observables, the approach for carrier phase ambiguity resolution with single frequency L1 measurements in a kinematic environment is discussed. Flight test results are given to demonstrate the centimeter accuracy achievable in position using pure carrier wave observations. Successful L1 ambiguity resolution during the flight test using a high performance single frequency 10-channel receiver is shown as well as the high position accuracy after this process. Variations in the time to resolve the ambiguities are discussed with respect to vehicle dynamics and monitor-aircraft separation. Modelling of the tropospheric influences using onboard meteorological data are shown to improve the pure carrier wave approach
