Abstract:	Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a concept that extends today’s RAIM by incorporating dual frequency and multiple constellations. ARAIM will dramatically improve the availability of horizontal guidance, and has the possibility to evolve to provide worldwide vertical guidance. A key feature of ARAIM is the Integrity Support Message (ISM). The ISM includes information about the constellations and satellites that the receiver requires in order to provide integrity to the user. Since it was first proposed, the concept of ARAIM and the ISM has evolved to take into account institutional and technical constraints, but there are still many open questions. In this paper we describe our vision for the ARAIM concept of operations for Horizontal ARAIM, which would be the first step in the deployment of ARAIM. We describe high level requirements for the different stakeholders (GNSS providers, the air navigation service providers, and the receiver manufacturers) by addressing the following topics: ISM origin, ISM latency, ISM broadcast, receiver requirements, and ICAO SARPs requirements.
