Probability Distributions that are Important When Assessing Barometric Aiding to GPS

M.J.A. Asbury, D.A. Forrester, C.S. Dixon and R. Johannessen

Abstract:	GPS coverage can be overcome by aiding from the barometric altimeter depends upon the durations of those imperfections, the variations of the barometric altimeter errors, the calibration errors and the geometries involved. The paper derives the statistical variations for all of these factors and shows that one of the most dominating features is that of the geometry between satellites and barometric input. The paper concludes that barometric aiding has potential for Supplemental Means navigation, but is unlikely to be useful for Sole Means.
