3.2.3 Position
The position display indicates the Lat/Lon values, the position status and its selection mode. With
Adjust, the position dada can optionally be corrected for position errors.
In front of each depiction of the
values LAT/LON, there may be a
symbol indicating a warning or
an alarm.

The meaning of the signs is explained in detail in chapter

About Position Sensors
Position sensors are treated as a part of the CCRS. See chapter III - 2.1 on page III-16 for details. This
means that the LAT/LON values indicate the position of the selected CCRP (Conning/RADAR/Track). For
this function the sensor locations defined on service level are utilized.
If more than one position sensor is connected to the system, a position monitoring function will auto-
matically be activated and will be running on the MFD

.
The data transmitted from a position sensor to the system may contain additional information about
validity , sensor type, sensor mode etc. These data are combined in the sensor label shown in the posi-
tion display.
Yellow
Input from the process is disconnected in the software, and the value is entered manually by
the operator
Red
Error in the Control and Supervision system, the indication is invalid or the value received
from the sensor is outside the legal limits
It must be noted that the necessary accuracy is achieved only if all positions used relate
to the same chart datum, preferably WGS 84.
- When using the system as a planning system, position coordinates obtained
from a chart with a datum deviating from WGS 84 must be converted to WGS
84 User Symbols and route data.
- The only position receivers that may be connected to the NACOS Platinum
system are those that output the position values in the geographical reference
system WGS84 via an interface as per IEC 61162-1.
- It must be ensured that an approved EPFS (Electronic Position Fixing System)
is connected, that means that all position sensors must accord to IEC 62388
(2007) and to IMO resolution MSC. 112(73).
