9.2 Basic Adjustments
9.2.1 Temporary Hiding the Chart Background
If ENC is set and the chart
presentation shall be hidden
just for a few seconds in order
to identify details of the radar
image, just press Hide
Overlay in the RADAR Video
group.
The result is an empty screen
except for the radar video.
9.2.2 Selection of Charts
The drop-down menu in the Charts group of the
permanent area provides access to the different
charts that are installed on your CHARTRADAR
system. Only vector charts are permitted for a char-
tradar and only these are selectable. Raster charts
(RNC) can not be used.
9.2.3 Matching the Chart with the RADAR Presentation
If the chart underlay is not matching the radar PPI, the user may adjust the position data of the position
fixing device. This function is available from the permanent area in the Position WGS84 group. For
details please see chapter III - 3.2.3 on page III-42.
9.2.4 References Used
The CHARTRADAR uses the same reference system for own ship’s position, speed, heading, time, etc.
as the RADARPILOT. The common reference point is called Consistent Common Reference Point
(CCRP). It can be selected from the drop down menu CCRP in the Display group of the permanent
area (select Conning which is the default, or radar, or tracking). For details please see chapter III - 2.1
on page III-16 ff and see chapter III - 3.1.4 on page III-28.
For Route Monitoring against ECDIS objects and user objects the CHARTRADAR uses the track control
reference point which is typically at the bow of the vessel. This point is also called the system position.
The guard sector (also called look-ahead sector) starts from there. For details please see chapter III -
2.1 on page III-16.
