Radar and NavNet3D

[Anonymous]

I have a NavNet 3D chart plotter with a 4kw radar. My problem is that when I overlay radar onto the chart plotter landmasses identified by the radar do not line up with landmasses of the chart. They are probably 10° to 20° off. Any help would be greatly appreciated.

This is most likely due to the fact that your heading input is off. What are you using as a heading sensor into the NavNet 3D? In addition the heading error might be amplified if you didn't adjust the radar heading in the radar section of the installation wizard.
