NACOS Platinum
For systems with integrated Track Control System (Autopilot) it is important to use the same reference
position for the track control and for the monitoring process of the ECDIS. For both purposes the so-
called System Position, located in the bow of the ship, is used system-wide.
In NACOS Platinum the System Position is called Track Control position, which can be selected with
CCRP = Track in the GUI as an optional reference point.

For measurements relative to the own ship (EBL, VRM, Cursor, target data) on the NACOS Platinum the
Conning Position is used normally. In contrast to a RADAR system, where the reference may also be the
position of the radar antenna, in a stand-alone ECDIS no alternative reference position than the Track
Control position can be selected by the operator.

the Conning Position
(CCRP = Conning)
The chart monitoring func-
tion of the ECDIS sub-
system is done for the
CCRP=Track Control Posi-
tion, i.e. the guard sector
(also called look-ahead
sector) starts at the bow of
the ship. Length and width
of the sector can be
adjusted in the ECDIS-HMI.
