Development of advanced RAIM minimum operational performance standards
Résumé
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a concept that extends today's RAIM by incorporating dual frequency signals and multiple constellations [1], [2]. The potential benefits of Horizontal ARAIM have been well established, both through simulation ([1],[2],[3]), and using flight data [4]. Looking further into the future, we expect that implementing horizontal guidance will pave the way for vertical guidance. As the concept of operations converges ([5], [6]), and the Dual Frequency Multi-Constellation SBAS Minimum Operational Performance Standards (MOPS) are being developed [7], it is time to start drafting the ARAIM receiver requirements. The goal of this paper is to describe a basis for the ARAIM MOPS as it has been discussed within aviation standards fora and the bilateral EU - US Working Group ([1],[2]) that developed the concept.
