Starting a position track
A position track permits the SN90 system to automatically control the tilt and bearing based on the movements of your vessel.
Context
The position track locks on a position defined by its latitude, longitude and depth.
The bearing and tilt settings are automatically adjusted to compensate for the movements of your vessel. The bearing line is automatically locked on the object to reflects its bearing. The marker is stationary. If the echo moves in the display presentation the marker will not follow.
Tip
By default, a new manually initiated tracked object is automatically given priority status. Relevant information about the priority target can be found in the lower 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.
On the User Settings Setup page, de-select New Manually Initiated Track if you do not want new tracked targets to become priority targets. This page is located in the Installation dialog box. To open the page, select Installation on the Setup menu.

Result
The marker is shown as a small triangle with or without a short identifying label. Once an echo has been provided with a marker in the display presentation it is regarded as an object.
Note
If you change the tilt and bearing settings manually, the position track is disabled. If you create a new marker and give this priority, the position track is disabled. The same applies if you start a new target track.
