Optimization of Angle-of-Arrival GPS Integrity Monitoring
The paper considers the navigation satellite systems integrity monitoring method which is based on the differences between measured and calculated azimuth and elevation of the navigation signal source respectively. Probability-based integrity monitoring characteristics such as probability of false detection (false alarm probability) and the probability of missing the violation of integrity (missing probability) were obtained. Different kinds of decision-making procedures were analyzed, and for the most important methods logical “AND” and logical “OR” optimal choice of decision thresholds was found. It was concluded that the logic “OR” method had significant advantage over the logic “AND” method in the most practical interest area of missing probability values for fixed value of false alarm probability.
