    GPS/DGPS Black-box Receiver

    The MX525A delivers position accuracy better than 2 meters in DGPS mode when using RTCM correction data. It also provides better than 5 meters accuracy in standard GPS mode. It is backward compatible with existing MX420 systems to make them compliant with the latest IMO requirements.


    Space Based Augmentation Systems (SBAS) like the European Geostationary Navigation Overlay System (EGNOS), the US Wide Area Augmentation Service (WAAS) and the Japanese MTSAT Satellite Based Augmentation System (MSAS) are being developed throughout the world. The MX525A can be controlled to use these systems to provide accurate positions in areas not covered by DGPS beacon stations, but covered by SBAS.
