Fluctuation: A Novel Approach To GNSS Receiver Testing

A. Mitelman

Abstract:	This paper introduces a novel method for testing GNSS receivers based on empirically observed C/N0 histograms. Raw data is gathered in an environment of interest and used to generate a simulator scenario with randomized power levels. The ensemble distribution of levels in the scenario is constructed to match the target distribution by means of a probability integral transform (PIT). The timing of the transitions between levels on all simulator channels is modeled with one or more Poisson random processes. Similarity between receiver responses to live and simulated signals is quantified by applying a twosided Kolmogorov-Smirnov (K-S) test to the cumulative distribution functions of time-to-first-fix (TTFF) data for each.
