Abstract

The Global Positioning System (GPS) has become a popular sensing system for positioning because it is free and always available and can be used in all weathers. However, the accuracy of GPS is dependent on the measurement factors selected by the surveyor. Therefore, the purpose of this research is to determine the optimal factors of the GPS positioning process. The selected process variables were measurement time and duration, recording interval, and mask angle. To determine the optimum conditions of these factors, a three-level Box-Behnken design was utilized. The results indicated that the optimum conditions of the experimental factors are 13 h as measurement time, 21.77 min as the measurement duration, 22.43 s as the range interval, and 8 degrees as the mask angle.
