4.12.6 Setting RAIM
RAIM (Receiver Autonomous Integrity Monitoring) checks the accuracy of GPS with the accuracy
level and displays the status.
When the reliability of the error that was obtained is 95% or higher, the state is displayed as
"SAFE" or "UNSAFE". When the reliability is 95% or lower, "CAUTION" is displayed.
SAFE: The position error is within the set accuracy level.
CAUTION: Cannot calculate with the set accuracy level.
UNSAFE: The position error exceeded the set accuracy level.
An accuracy level of RAIM can be set.
An accuracy level can be selected from OFF, 10m, 30m, 50m, and 100m.
To perform GPS independent position fixing, set 30m or more. If GPS independent position fixing
is performed by setting 10m, the reliability 95% is not satisfied and this may result in “CAUTION”.
When OFF is set, "RAIM OFF" is displayed on the screen, and the RAIM function stops. Therefore,
when RAIM is OFF, the system cannot perform calculation as to whether the reliability is within the
accuracy level.
For a processor with two sensors connected, the sensors must be set individually.
In this example, sensor 1 is connected. The same procedure is applied for setting sensor 2 also.

4.12.7 Setting a geodetic system
A geodetic system of the position that was fixed can be set.
For the geodetic systems that can be set, refer to “Appendix 1 Geodetic System”.
For a processor with two sensors connected, the sensors must be set individually.
In this example, sensor 1 connected. The same procedure is applied for setting sensor 2 also.

RAIM Description
RAIM ACCURACY LEVEL Set an accuracy level of RAIM.
Select from OF
, 100m, 50m, 30m, and 10m.
DATUM Description
DATUM Set a geodetic system.
For the geodetic systems that can be set, refer to “Appendix 1 Geodetic
S
stem”.
RAIM
RAIM is the abbreviation of Receiver Autonomous Integrity Monitoring and checks, in the
receiver, if the position accuracy that was fixed by GNSS is within the necessary accuracy.
