GPS/DGPS Black-box Receiver

The MX525A delivers a position accuracy better than 1 meters in DGPS

mode when using RTCM correction data. It also provides better than 3

meters accuracy in standard GPS mode. It is backward compatible with

existing MX420 systems to make them compliant with the latest IMO

requirements.

Beacon

Navigation authorities around the world have installed DGPS radiobea-

con networks that broadcast free RTCM correction information. With the

use of its’ built-in beacon demodulator, the MX525A uses these real-

time corrections to deliver accurate, reliable positioning when in range of

a beacon transmitter. Can be controlled by the operator to accept RTCM

data from external sources using the MX Control and Display

Unit (MX CDU).

Augmentation

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 pro-

vide accurate positions in areas not covered by DGPS beacon stations,

but covered by SBAS.

RAIM

Receiver Autonomous Integrity Monitoring (RAIM) is a safety feature in

the MX525A which continously veries the integrity of the GPS system

to ascertain its’ accuracy and reliability. When position errors 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

through the MX CDU.

Interface

The MX525A features two independent NMEA compliant serial ports,

which are identical to those of the MX421B-10 DGPS Smart Antenna.

MX525A interfaces directly to the MX CDU or to other NMEA 0183

compatible devices.
