Abstract: ARAIM is an evolution of the RAIM integrity technique recently developed to protect multi-constellation users by means of robust user algorithms. The ARAIM solution developed for Aviation includes an offline ground monitoring architecture, which provides updates on the nominal performance and fault rates of multiple constellations. This integrity data is contained in the Integrity Support Message (ISM) that is generated by an offline ground monitoring network and is provided to the airborne fleet through the GNSS signals. The current ARAIM concept has been designed initially to serve the Aviation sector. Nevertheless, the concept can be used by other user communities, in particular, the markets comprising critical applications with a need of GNSS integrity capability. A wide range of applications, and specially safety critical applications, can in principle take advantage of this service, or a modified version of it, since they have similar and even more demanding requirements than aviation users. Rail, Maritime, Road, UAVs, LBS and Space User Sectors are analysed as potential target sectors in this work. In this paper, non-aviation sectors, applications and the use of other GNSS integrity technologies are analysed exploring the user needs in order to identify potential applications for the penetration of ARAIM. Non-aviation applications which could be fulfilled with the current ARAIM concept for Aviation are identified. For those non-aviation applications which cannot be fulfilled with the current ARAIM concept, a gap analysis is conducted in order to identify potential areas of improvements which allows to define suitable ARAIM evolutions for those non-aviation applications. Finally, a dedicated experimentation is conducted in order to proof the concept of the ARAIM evolutions and assess whether they could comply with the user requirements of non-aviation applications.
