GPS/DGPS from Saab Transpondertech

IMO require SOLAS class ships to carry a type- approved GPS and further that any new GPS installation shall be compliant with the new performance standard for GPS.

This was defined by MSC 112(73) and resulted in the associated test standard IEC 61108-1 Ed. 2. Saab TransponderTech can now offer a number of IMO-, Wheelmark- and US Coast Guard-compliant GPS and DGPS solutions, either as stand-alone Navigation Systems or as additions to existing Saab AIS systems.

 The new navigation products from Saab are self-monitoring and extremely user friendly. They perform continuous RAIM (Receiver Autonomous Integrity Monitoring) calculations. This allows the Officer Of the Watch (OOW) to set the required navigation accuracy for any stage of the journey. The R4 Navigation System will then give continuous feedback on whether the accuracy requirement is being met.
