End to End On-line ARAIM Real-time Experimentation and Demonstration with magicARAIM Suite

During the last few years, the concept of ARAIM has acquired a more significant presence and relevance over the aviation community. Different stakeholders and standardization entities are working on the development of ARAIM services to complement other GNSS-based aviation navigation means such as RAIM, GSBAS or SBAS. Currently, RAIM receivers allow usto assure the integrity of the navigation information received by the aircraft from GNSS satellites. The receivers perform integrity checks considering a set of fixed assertions regarding the nominal performances and probability of faults for single-frequency GPS satellites. The mechanism envisaged by the ARAIM (Advanced Receiver Autonomous Integrity Monitoring) solution consists in an evolution of the traditional RAIM concept providing a mechanism to update the information describing the fault rates of GNSS core constellations. In order to compute this information, a ground segment infrastructure shall be responsible for monitoring the GNSS constellations, computing and codifying the ARAIM integrity support message or ISM. This new ARAIM service expands the traditional single-constellation, single-frequency RAIM solution towards the multiconstellation, dual-frequency receiver concept. Under this configuration, the service aims to provide world-wide horizontal and vertical guidance down to LPV-200 procedures. In this context, GMV has developed the magicARAIM suit. The platform covers the ISM generation, performance monitoring and a user terminal. As a consequence, it provides an end-to-end testbed environment capable of supporting trade-offs oriented both to the development of the ARAIM service and its user segment. At this respect, the present paper aims to: - Introduce and present the different ARAIM services. - Describe magicARAIM end-to-end platform, including the ISM generation and the associated analysis tools. - Present the achieved performances when running experimentations with the platform and considering GPS and GALILEO dual-frequency scenarios on the basis of RT CORS stations processing for an On-line ARAIM Architecture.
