Abstract:	Advanced RAIM is an extension of RAIM that will integrate up to four core constellations (GPS, Galileo, BeiDou, and GLONASS), and signals in two frequencies (L1 and L5). The performance standards and an example Horizontal ARAIM user algorithm, which will be included in the future release of the DFMC SBAS Minimum Operational Performance Standards (MOPS) (ED-259B/DO401A), are currently being developed. A key part of these standards is the set of offline tests designed to demonstrate compliance with the integrity and continuity requirements. In this paper, we go over the key aspects of the tests described in the draft DFMC SBAS MOPS and provide a rationale or justification for each one of them.
