LAAS Integrity Monitoring Methodology: Least Squares versus Mid-Value Selection

P. Bastiaan Ober

Abstract:	This paper provides a description of the general concepts behind the integrity providence of locally augmented GPS. It shows why the exact integrity is hard to evaluate, even when simple error models are used, and explains the problems that will have to be resolved before a full performance assessment can be obtained. Integrity is mainly provided by using redundant receivers. Therefore, the paper pays special attention on two ways to combine the outputs of multiple receivers. It discusses the merits of both the traditional error detection and identification scheme and a simple robust scheme as mid-value selection, which proves much easier to evaluate.
