Hydrophone VRU Offset  

The VRU offset is the difference in angle between the installed hydrophone and vertical (static offset). (It 
can also represent the offset between the Remote Dynamic Motion Sensor and the Hydrophone.) Offsets 
can occur either due to a misaligned hydrophone or from changes in trim to the vessel. The system allows 
for either manual entry of attitude error corrections or auto correction via the hydrophone's internal VRU 
for off-setting the static tilt of the hydrophone/staff. The attitude (pitch/roll) offsets are error constants 
that subtract from the remote or external dynamic motion sensing system data to compensate for the 
nonvertical installation of the Hydrophone shaft (or difference between DMS and Hydrophone).
