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
