Assessment and Refinements of RAIM Certification Procedures for FAA/DOD Receivers

Prem K. Munjal and Steven Sedlacek

Abstract:	RAIM certification procedures for FAA have been developed and were documented in Technical Standard Order and Minimum Operational Performance Standards for GPS aircraft navigation. This paper presents results of a simulation analysis that were used to evaluate the certification procedures for both civilian and DOD receivers. This paper also presents details of simuiation function and how the conditions prescribed by the test procedures are generated. The results show that the pre- sent certification process should be modified so that passing the certification process will give a high proba- bility that the receiver actually meets the error detection requirements. Also, a self-contained method for ranking points in order of difficulty for the basic RAIM algo- rithm is presented. This method may make it possible to set availability thresholds without depending on previous simulation results. The current GPS constellation archi- tecture-not the GPS 21 Optimal Satellite Constellation-is used for the analysis.
