American Dynamics SpeedDome Ultra 8 Operator's Manual page 77

In this example, the current pointing position is 60° from North. The tilt elevation is 12° above
the virtual horizon. Panning to the left points the dome towards the Northeast. Panning to the
right points the dome towards the East. If you tilt below the virtual horizon, the negative
values will be displayed along the left edge (for example, –25). The elevation values range
from +25° to -90°.
If you pan to a position that corresponds to a well-known navigational heading, the label
corresponding to the heading appears in the center position. Figure 63 illustrates the
navigational headings and their corresponding degrees from North.

In this illustration, the black circle in the center represents the dome, the dotted circle
represents the pan axis, and the arrowheads represent panning the dome to the right.
Figure 64 represents pointing the dome precisely at 225° from North (Southwest) with a tilt of
25° below the virtual horizon. Panning to the left points the dome towards the South. Panning
to the right points the dome towards the West.
