Using the positioning data, water elevation and pitch, roll and heading information, X, Y and Z data is produced and a 3D image can be built up of the dam conditions.

The sensor is a three-axis, tilt-compensated compass that uses a two-axis accelerometer for enhanced performance. Tilt range (Pitch and Roll) is ±60°. The unit compensates for Hard Iron Distortions, Ferrous Objects, and Stray Fields. The data is transmitted 10 times per second.
