Abstract:

As part of the development of the Advanced RAIM, a baseline user algorithm was developed to demonstrate the feasibility of the concept. A first version was published in 2012 and subsequent modifications were made available in different forums. The purpose of this paper is to describe a possible set of updates to the original baseline algorithm that integrates the latest safety analyses (the effect of temporal exposure and the effect of exclusion), that exploits the proposed default Integrity Support Data (the parameters describing the nominal error model and the faults), and that enables the use of techniques to drastically reduce the computational complexity.
