This manual describes the operation and installation
of the MX521A GPS/ DGPS and older version MX521
antenna sensors.
They were designed to work either interactively with MX
Control and Display Unit (MX CDU) or as a stand-alone
positioning device for other non-MX applications.
The MX521A smart DGPS antennas can achieve better
than 2-meter DGPS accuracy in areas with good beacon
differential coverage and autonomous GPS accuracy
better than 5 meters.
When connected to an MX-CDU (i.e. MX420 or MX5xx),
the MX521 can be controlled to function in several
modes, namely;
GPS only •
Differential correction search mode in Auto, Database •
or Manual
WAAS* (Wide Area Augmentation System-US system) •
EGNOS* (European Geostationary Overlay System) •
RAIM (Receiver Autonomous Integrity Monitoring) •
The MX521 sensors were designed to be used as:
Source of GPS/DGPS positioning for MX CDUs •
including MX420 & MX5xx series CDUs
Retrofit of IMO compliant GPS and AIS installation •
Source of position for ECDIS and other charting •
software
Before installing the MX521 smart antenna, please read
this manual carefully to ensure proper installation and
operation of the unit.
*Not yet recognized by IMO as official differential correction
system
