1 Place the cursor over the echo you wish to track.
2 Right-click to open the shortcut menu.
3 Select
Initiate Track
.
The tracked target is regarded as an object , and it is identified with a circle and two lines.
The two lines reflect the size of the current tracking area. A new manually initiated tracked
object is automatically given priority status. The bearing line is automatically locked on
the object to reflects its bearing.
Note
If you change the tilt or bearing settings manually the priority status is lost. The ST90
system will still attempt to track the target, but the tilt and bearing settings are not adjusted.
The priority is identified with a "P". Only one single object can be given priority status. If
you start tracking a
new target the first target will loose its priority. The same applies if you
give priority to another marker. The tracking of the first target will however not stop, and
the target marker is still shown.
Relevant information about the tracked object can be found in the bottom left corner of the
view. If you think the text is small and hard to read, double-click on the text field. This
will increase the text size.
Tip
Under certain circumstances the target tracking may not follow the intended echo. This may
for example happen if the tracking area is too large. You can initiate manual tracking by
placing multiple markers on your target echo as it moves in the view. This location of the
markers in the view will then show you the historic path of the target.
Deleting a marker
There are two ways to delete a marker. You can use the shortcut menu, or select
Delete
in the
Objects
menu.
Tip
You can delete a single marker, or multiple markers simultaneously, by selecting
Delete
in
the
Objects
menu. If you use
Delete Marker
on the shortcut menu you can only remove
one marker at a time.
1 Place the cursor on the marker you wish to delete.
2 Right-click to open the shortcut menu.
