Radar/Chart Overlay
You can overlay the Radar image directly on top of the Chart window pane, aligning
the Radar with the chart until all targets are displayed on the chart in their exact
location. Radar overlay helps you navigate the chart better, and the chart brings
context to what can often be a confusing display of radar blobs.
When radar overlay is on, important radar information is also displayed in the
corners of the Chart window pane.
WARNING:
Radar Overlay on your electronic charts requires a high speed and
well-adjusted compass. Slight deviation errors are significantly magnified
with radar overlay. Make sure that you have set up your radar and digital
compass (heading sensor) correctly.
TIP:
Turn Radar Overlay on by right-clicking on the Chart window pane and
selecting Radar Overlay from the Chart Context Menu.
REMEMBER:
The Auto Range feature keeps the chart scale and the radar range
synchronized, making it easy to understand the radar in context with the
chart. To adjust the radar range, zoom out using any of the chart zoom tools.
To turn on Radar Overlay, place focus on the Chart window pane and select
Context Menu | Radar Overlay.
Targets Panel
Currently, in Jeppesen Workboat Navigator, the Targets panel of the SysInfo window
pane tracks only AIS targets. Look for updates for Radar targets in future versions
of Jeppesen Workboat Navigator.
Radar Overlay and MARPA
Targets shown on-screen can be internally generated rather than generated by
external sources.
How It Works
If you are using the radar overlay feature and see a potential target on the Radar
window pane, bring focus to the Radar window pane and choose Acquire Target
Mode from the Radar Context Menu. The mouse will convert to the Acquire Target
mouse. Jeppesen Workboat Navigator will begin collecting data for each target
clicked on by the mouse.
Jeppesen Workboat Navigator will begin to gather information about the selected
target and generate speed, course, CPA, and TCPA information based on GPS
position and Radar data.
