5.2 First Run of Navigation Processing

For processing this data I set the WINDOW = 12, NAV SOURCE = SHIP (mounted sonar),
ITERATIONS = 1, HEADING = SHIP, SPEED FILTER = 0.5 to 7.0 knots. After only one
step of processing the image below shows a relatively smooth line.

While this might be adequate for getting good bathymetry processing results, processing
the navigation a second time can help remove the remaining sharp bends from the
navigation track.

5.3 Second Run of Navigation Processing

After the second step of processing the image below shows a relatively smooth trackline.
