5.3.3 Target
Types
Four target types are available; Point, Line, Spiral and Home. The use of each depends entirely on
the application of your attached instruments. The following sections describe the usage of each
target type. In order to become familiar with the operation of the unit, it is recommended that
adequate time be spent experimenting with each one to ensure the desired results.
a) Point
The Point target results in the 2AP aiming at a single point for a specified duration of time. In this
case, the user must enter the start position in azimuth and zenith coordinates as well as the time
duration in seconds. It is important to note that for a Point target the start position and end position
are the same, therefore there is no provision to enter end position coordinates.
If a Point target is defined with a relative start position, this will simply have the effect of keeping the
2AP its current position for a specified duration. This may be desired if a delay is required or if the
instrument needs to stay in position for a lengthy period. Figure 5.4 shows a Point target with the
start/end position in blue and the current 2AP position with a red circle. If this was a relative target,
the blue cross-hair and red circle would be the same point.
