Exclusion for Advanced RAIM: Requirements and a Baseline Algorithm

摘要

Advanced Receiver Autonomous Integrity Monitoring is a concept that extends RAIM to multi-constellation and dual frequency that could provide worldwide coverage of vertical guidance [1], [2]. A baseline algorithm for the user receiver has been described in [3]. This baseline algorithm included the computation of the Protection Levels, the Effective Monitor Threshold, the accuracy, and a preliminary description of an exclusion algorithm. The objective of this paper is to develop a set of requirements for the exclusion algorithm (as there is for the computation of the Protection Levels) and to propose a baseline algorithm that fulfills these requirements, therefore attempting to complete the work started in [3].
