Selecting the Reference Targets for Reference Target Tracking
If at least one fixed target
 1)
 is selected as a reference target, the radar can determine own ship’s speed
vector with the aid of this target’s relative motion. By means of this "reference target tracking", the radar
also acts as a speed sensor, and can be called up as such under REFERENCE TARGET SPEED.
Selecting a reference target: Click on the fixed target with the
MORE key, and then click on SELECT REFERENCE TARGET (with
the DO key).
Up to five reference targets can be selected.
The speed input "reference target tracking" is treated as a
ground stabilized speed sensor (speed over ground), displayed
as COG/SOG data.
The first reference target is given an  R as its target label. If there is more than one reference target
defined, all reference targets are given an independent sequential number in addition to the letter R.
Cancelling the selection: Click on the reference target with the MORE key, and then click on DESE-
LECT REFERENCE TARGET
 (with the DO key).
CAUTION:
During reference target tracking, it shall be checked repeadly if the
selected reference targets are still displayed as fixed targets.
1)  
If a moving target is selected by mistake, the own speed determined will be incorrect. To ensure accurate determination of speed, several
fixed targets should be checked as references.
