Characterization of Multipath LAAS Ranging Error Versus Structure Size, Orientation, and Position

Edward V. Sayadian and William G. Dyer

Abstract:	This paper examines the relationship between reflector size, orientation, and position, and the Local Area Augmentation System (LAAS) reference station multipath error component of the ranging error. Specifically, this paper presents a methodology based on analytical and simulation work which establishes upper bounds on the probability that the multipath error component exceeds a predetermined threshold. The probabilities are conditioned on reflector size, orientation, and position. Initial siting constraints are then developed based on these resulting probabilities. The results show that reflective structures up to 100 meters wide by 200 meters high in size and as close as 1.5 km have a upper bound probability on the order of 1 x 10m6 of producing ranging errors over 0.1 meters.
