Flight Test Evaluation of a Differential Global Positioning System Sensor in Runway Performance Testing
Abstract
This study discusses the use of a carrier phase differential global positioning system (DGPS) receiver set in basic takeoff and landing performance flight testing. A technique for using DGPS receivers as theodolites in takeoff and landing performance tests is developed. Both position and velocity data are available from a DGPS receiver. As a result distances can be calculated by differencing the position coordinates or by integrating the available ground velocities. Both of these techniques are used and compared to a traditional video theodolite system for ground roll distances. . The viability of using DGPS ground speed data in lieu of air data in calculating the distance to clear a barrier is also explored. These methods are used to determine the nominal takeoff and landing performance of an experimental general aviation airplane. Test results are mixed. DGPS velocity integration yields good results for ground phase calculations. All other results are inconclusive.
