5.3 Position Sensor
There are often several position sensors connected to the system. One of them has to be selected. As
an alternative to selecting a position sensor, it can - if necessary - also be specified that the system posi-
tion is to be determined on the radar by dead reckoning (EP = Estimated Position) using the gyro heading
and the speed data of the selected speed sensor.
After the position sensor has been selected, the accuracy of the position data must be checked continu-
ously. Constant errors in the transferred position can be compensated manually.
General Remarks about Position Data
On the radar, it is basically necessary to distinguish between the following positions:
1. System position: The display is shown in the position display when the cursor is situated outside
the PPI. "System position" is normally defined as a position in the forward part of the ship - usually
the location of the transducer of the DOLOG or of another installed log.
2. Reference position for bearings: All displays relating to own position (own ship symbol, VRM/EBL,
range/bearing of the cursor position, CPA/TCPA) refer to the antenna position of the radar that is
being operated. This is made clear in the Position Display by the entry REF RADAR.
☞ There is no LAT/LON display of this position, but in the small display-ranges the LAT/LON
values can be read off as the cursor position if the cursor is moved to the radar origin.
3. Cursor position: The display is shown in the position display when the cursor is situated within the
PPI. This display indicates the absolute geographical position.
All LAT/LON values are based on the geodetic datum "WGS 84".
☞ Important: Only position receivers may be connected to the radar system that output the position
values in the geographical reference system WGS 84 via an interface as per IEC 61162-1

Display of the Position Data Used
In the Position Display, the position data used in the system
are displayed:
-Behind POS: the selected position sensor.
-Behind LAT and LON: the system position.
-Behind COG and SOG: the values of course and speed
over ground that are transferred from the selected speed
sensor.
-Behind ADJUST: the value of the manual position-correc-
tion in metres N/S and W/E,
☞ If a manual position-correction has been entered, the LAT
and LON values have a yellow background.

IEC 61162-1 largely corresponds to NMEA 0183 Version 2.30 of 1st March 1998.
