installed. This sensor may be mounted anywhere on the vessel. Because of this, the risk of
stabilization offset misalignment is present.
The two screen captures below illustrate how the ST90 system can provide inaccurate data if
the stabilization offset is misaligned. In both examples, the tilt is set to approximately 24
degrees, and you are looking at the echoes from a flat bottom at a very short range. The
first example is made without any offset errors, and the echoes from the bottom are evenly
distributed in the circle. On the second screen capture, a 3 degrees roll offset error causes
the echoes to be "distorted". This error will of course be more visible on longer ranges.
