This report presents the results of an evaluation of the suitability of using handheld Global Positioning System GPS receivers using course acquisition code to perform an air data system calibration. The two testbeds were an aerospatiale Tobago and a Rutan Long EZ, both general aviation single engine land aircraft. The test objective was to evaluate the suitability of commercial GPS receivers as measuring devices for general aviation air data system ADS calibration. Emphasis was on a handheld GPS and data collection devices. The goal was to develop a technique to accomplish an ADS calibration on a low-speed under 200 knots calibrated airspeed aircraft, using only commercial GPS equipment. After an all-altitude airspeed comparison technique was developed, a calibration of the ADS of an uninstrumented general aviation aircraft was completed. Overall, the commercial OPS receivers were suitable as measurement devices for ADS calibrations. Any current, commercially available receiver could be used without the need for differential GPS receivers or rigorous postprocessing of receiver data.
