This antenna has sub-meter accuracy with Beacon DGPS corrections. MX421B is also offered with 5 Hz position output and is used in race boats because of high accuracy.

Beacon
Navigation authorities around the world have installed DGPS radiobeacon networks that broadcast free RTCM correction information. With the use of its’ built-in beacon demodulator, the MX smart antennas use these real-time corrections to deliver accurate, reliable positioning when in range of a beacon transmitter. The antennas can be controlled by the operator to accept RTCM data from external sources using the MX Control and Display Unit (MX CDU).

RAIM
Receiver Autonomous Integrity Monitoring (RAIM) is a safety feature in the MX smart antennas which continuously verify the integrity of the GPS system to ascertain its’ accuracy and reliability. When position error exceeds a pre-set limit, the MX CDU alerts the operator to take precautionary measures. RAIM is one of the latest requirements under IMO MSC 112 (73) regulation. This RAIM feature can be accessed by the operator using the MX CDU.

Interface
The MX smart antennas feature two independent NMEA compliant serial ports.
They interface directly to the MX CDU or to other NMEA 0183 compatible devices.

DGPS Smart Antenna Receiver
The High Accuracy MX421 delivers position accuracy better than 1 meter in DGPS mode when using RTCM correction data. It also provides better than 3 meters accuracy in standard GPS mode.

Option for 5 Hz Position Update
MX421B-10 can be optionally upgraded to output 5Hz position update.

DGPS Smart Antenna Receiver
The MX521A 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.
