Optimal distance for moving long baseline positioning system with distance-dependent measurement noise

摘要

This article investigates the effect of distance-dependent noise on optimal transponder distance in a moving long baselinepositioning system. First, according to the positioning model of the moving long baseline positioning system, the relationship between measurement noises and positioning error is established. Second, a cost function is proposed to evaluatethe positioning performance. Then, based on the optimal formation, the optimal distance is deduced. Finally, the relationship between the optimal distance and the parameter for the distance-dependent error is proposed. By using this relationship, the effect of distance-dependent measurement noise on optimal distance is analyzed. Simulation examplesillustrate the results.
