Abstract
An experimental testbed and a data analysis procedure were developed to evaluate the dynamic performance of global positioning system (GPS) receivers. Receiver I - radio beacons differential correction based GPS receiver and Receiver II - satellite differential correction based GPS receiver were evaluated. Under dynamic conditions, the position errors were 1.39 and 1.71 m, the speed errors were 0.067 and 0.068 m/s, and the direction errors were 9.7° and 16.9° for the receivers I and II, respectively. The results indicated that the trends in the dynamic accuracy of GPS receivers were completely different from those for static accuracy. The study signifies the need for evaluating the GPS positioning errors under static as well as dynamic conditions to correct the errors.
