GPS5 - RAIM Status Screen (for RAIM Enabled
Models Only)
RAIM (Receiver Autonomous Integrity Monitoring) is a
standard feature in the MX500 CDU. The RAIM feature is
mandatory for IMO compliant vessels. It alerts the op-
erator that a condition may exists in the GPS positioning
solution that reduces the desired accuracy of the ship’s
position.
This feature requires at least five or more GPS satellites
to operate properly, four satellites or less are considered
to be a caution or unsafe RAIM condition. If the statis-
tical RAIM error exceeds a selected limit (100 meters
default) a “RAIM Unsafe” or “RAIM Caution” alarm will
be indicated in the MX CDU.
This means that the the RAIM estimated position error is
equal or greater than the preset limit. The operator is ad-
vised to take extra precautionary measures when using
the navigation solution until the RAIM indicator switches
to “RAIM safe” condition. When less than 5 satellites
are receivable a “RAIM Caution” will be indicated.
The GPS5 screen shows the position Lat/Long, height of
antenna, HDOP, number of satellites used, the satellite ID
number that may cause the statistical error and its bias
