Driver for PGS Nav Header output strings.
Driver to be used to generate output strings every QINSy fix update, containing the current line name, the fix number, date and time of position, and the easting and northing from the QINSy system to a Dragged Array onboard PGS OBC vessels.
Two output modes are:
- Position for currently selected output position, as set in the Controller's Options
- Steered Point: position for currently active steered point, determined by the Controller (Online)
The output rate of the PGS header is every fix. The last calculated position will be skewed to the time of fix.
Steered Point Output: If the computation fails for the current steered point, its position will be predicted for the number of seconds set in the Filter option in the Controller (default 10 s) and then changed automatically to the next steered point.
If there is no more steered point left, the last known position will be outputted.
Except when the "Steered Point" option of this driver has been selected, the appropriate output node must be selected before the driver starts cycling.
After going online with the Controller for the first time, select an output node in the Computation Setup.
In case of outputting the Steered Node position, the user has to set up also one or more Steered Point.
