The 3D viewer allows you to visualise your receiver's data on a real-time 3D polar diagram. You can switch between 2D and 3D modes by clicking the buttons at the bottom of the screen.
The polar view gives you an indication of your receivers range. Hover your mouse over areas to see the maximum distance of received signals. It may take some time for your receiver to build up enough data to provide an accurate visualisation. Data is reset every 24 hours.
The aircraft view allows you to see a real-time view of the aircraft your receiver is currently tracking.
To adjust the camera make sure you are in 3D mode and then simply click and drag your mouse. Use the scrollwheel to zoom in and out, and right-click to pan the camera.
