But analysis of raw motion data with iHeave permits a more accurate determination of real heave motion experienced by a vessel and enables output of precise heave values for all ocean swells.

Operating in near real-time, iHeave can process F180 data online, resulting in a processed heave file being ready for inclusion in multibeam bathymetric data only a few minutes after completion of a survey line. In conventional heave scenarios, where long-period heave is not a significant problem, the facility is also able to generate higher accuracy data than is possible in real-time.
