Abstract

Angle-of-arrival (AOA) integrity monitoring method for global-navigation satellite systems (GNSS) is discussed. In accordance with the AOA method, the direct decision making procedure (DDMP) about integrity presence or absence is created on the basis of direct antenna array signal processing. The DDMP is statistically simulated, and thus the most important characteristics, such as false alarm and missed detection probabilities, are estimated for different planar antenna arrays. The results of simulations show the algorithms efficiency areas for different structures of antenna arrays, so that finally the relationship between the number of antenna elements and missed detection probability are achieved for different number of analyzing signals. Comparison of DDMP with the decision making procedure for the AOA method, based on direction finding results post-processing, shows efficiency of DDMP both in terms of probability based characteristics and required computational costs.
