Technical Requirements on PNT Consolidated technical specification of user needs
Reliability should be measurable and scalable! IMO MSC.233(83) intends the application of RAIM to assess the GNSS based provision of PVT data. The INS (IMO MSC.252(83); IEC 61924) applies plausibility and consistency checks to assess the PNT data provided by several ship-side sensors. IMO A.915(22) specifies minimum requirements on horizontal position data given in unambiguous terms of accuracy, integrity, continuity and availability.
Harmonized meaning of integrity information Management of integrity within systems operating with distributed components and services Equivalent specifications for other navigational data (e.g. SOG, STW, ROT, Heading, …) Crossover from minimum to scalable requirements (accuracy, integrity) by consideration of specific tasks and their temporal and spatial dependencies
