Real time attitude determination is emerging as a promising new application of global positioning system (GPS) technology. Through the use of a special GPS receiver and multiple antennas, which perform differential carrier phase measurements, attitude can be determined as accurate as one milliradian in real-time for dynamic platforms. However, achievable accuracies are a function of the satellite geometry, and until recently the GPS constellation geometry was insufficient to provide continuous attitude data. This paper addresses the feasibility of integrating a GPS attitude determination system (ADS) on an unmanned aerial vehicle through the utilization of software simulation tools, which allow the user to evaluate ADS performance of a dynamic host platform based on satellite visibility.
