RAIM Feature
RAIM (Receiver Autonomous Integrity Monitoring) is a fault detection feature that works in
conjunction with the MX antenna unit. It gives the operator timely warnings when the GPS
system error exceeds the pre-set limit of 100 meters. This feature requires at least five or more
GPS satellite to operate properly. There are three RAIM states, namely:
• RAIM safe (R+) - system error is less than 100 meters
• RAIM unsafe (R-) - system error is equal or more than 100 meters
• RAIM caution (R?) - less than 5 satellites are available
The Enabled RAIM and RAIM alarm can be disabled by removing the check mark next to
them. The RAIM protection radius can be either 10 or 100 meters. Default setting is 100
meters.
Lat/Long Offset
This feature allows the operator to enter the Latitude and Longitude offset values between
the center of the ship to antenna position.

Note:
Heading data is required to enable this function.
GNSS Mode
Depending on the antenna type in use, the operator can select whether the position Lat/Lon
will be determined using autonomous GPS satellites only or combination of GPS and
GLONASS satellites. The GPS+GLONASS selection becomes available only when the GS70/
MX521B or MX575D/HS80A antenna model is in use.
Autonomous GPS position fix is indicated by a “GP” icon in the status bar while GPS+GLONASS
is indicated by “GN” icon.
