On the use of Multiconstellation-RAIM for Aircraft Approaches

P.B. Ober, D. Harriman

Abstract:	This paper deals with the question: “Under which conditions future RAIM-based GNSS (in particular using GPS and Galileo) could be used for applications beyond NPA?” It shows that some often-used reasoning about the performance of RAIM-FDE algorithms contains fundamental flaws, which may lead to overestimation of performance. Furthermore, concerns are raised about the general assumptions of single failures and normally distributed measurement errors when RAIM would be used for demanding applications such as Approach with Vertical Guidance (APV)-I or APV-II approaches.
