Using Multiple Reference Stations to Enhance LAAS Performance: Experimental Results

Curtis A. Shively, Hiep N. Nguyen

Abstract:	Performance of the FAA’s Local Area Augmentation System (LAAS) is expected to benefit from use of multiple ground reference antennas if they can be sited so that the multipath among them is uncorrelated. This paper presents experiments investigating the benefit of multiple ground reference stations for a user also located on the ground. These experiments were conducted in open fields to allow more references (3 to 4) and wider spacing among them than in a previously reported experiment. The correlation of multipath between antennas is examined for close and wide antenna spacing. Improvement in accuracy is characterized by the reduction in position error variance for the reference corrections applied separately and averaged together.
