Opis:: Although integrity concepts for Global Navigation Satellite Systems (GNSS) are ubiquitous in the aviation community, integrity algorithms of comparable maturity have not yet been developed for maritime users. The International Maritime Organization (IMO) specifies requirements different from those specified by the International Civil Aviation Organization (ICAO). These different requirements affect the design of the integrity algorithms with respect to integrity risk allocation and threat space. This paper describes a novel integrity algorithm based on conditions valid for maritime users. The performance of the novel integrity algorithm has been assessed and compared to a conventional Receiver Autonomous Integrity Monitoring (RAIM) approach consistent with IMO requirements.

Opis:: Signals from Global Navigation Satellite Systems are the primary source for Position, Navigation and Time (PNT) information onboard any vessel today. As these signals are prone to interference, a maritime backup system is needed to provide reliable PNT data, R(anging)-Mode is such a system. It utilizes existing maritime radio beacons or base stations of the Automatic Identification System (AIS) by adding ranging components to the legacy signals. The first modified radio beacons transmit medium frequency (MF) R-Mode signals in northern Germany. This paper has described the current state of the authors’ research and development activities at the receiver level for MF R-Mode signals. The receiver platform has been introduced, which was based on off-theshelf components and the implemented algorithms for distance estimation have been explained. Furthermore, the results of the first ranging measurements have been presented, which have shown the general suitability of the R-Mode technology as a source for maritime positioning and timing data.
