Gaussian Bounds of Sample Distributions for Integrity Analysis

We present a method to determine gaussian overbounding distributions used in integrity analysis. This method overcomes the limitations of previous techniques by combining them, through the determination of an intermediate symmetric and unimodal overbounding distribution. This method is the basis of a MATLAB toolset that computes strict gaussian overbounding distributions for any sample distribution. We apply the method to the determination of the overbounding distribution of GPS clock and ephemeris errors for Advanced RAIM.
