Adjusting the Radar Heading Line Rotation
This process allows you to align the radar transceiver with the center line of the
vessel and only needs to be set once. This is a different function than aligning your
heading sensor so make sure you are adjusting the radar’s physical heading line to
match the center line of your vessel.
One way to do this is to simply eyeball the difference. However, it is easiest to do this
using the radar overlay feature. If the charted land does not appear to line up cor-
rectly with the radar return for the same land mass, use the rotate scroll bar to adjust
the rotation angle until the overlaid image aligns correctly.
Remember
: Make sure you have a heading sensor connected to the PC.
Without a heading sensor, the Nobeltec Navigation Software cannot align
the image correctly onto the chart. To see if you have heading connected,
add the Heading console item to the console and verify that it does not read
N/A under
Tools | Options | Console | Heading
check box.
To adjust the Transmit Trigger Delay setting:
1. Start the Nobeltec Navigation Software and open the InSight Radar window.
2. When a radar image appears, click the Radar drop-down menu; then select Initial
Radar Setup
.
Enter the compass master
correction value in the field
provided.
Because the master value
affects all degrees equally,
make sure that you enter it
before you proceed to
creating a compass
deviation table.
