What does Post-processed Heave do for my Survey ??

New Heave processing algorithms have significantly improved the way heave estimates are calculated. This, in turn, greatly reduces heave artifacts in the most challenging survey conditions, especially in long period swells and quick turn-induced (horizontal acceleration) heaves.
