Applanix has announced that its POS MV product line has been enhanced by the introduction of TrueHeave technology. This improved filtering tool provides much more accurate heave estimation, even in the most challenging survey conditions. This results in a significant reduction in heave artefacts in survey data and eliminates the need to tune the heave filter to produce optimal results. In addition, TrueHeave reduces filter settle time as compared to a traditional heave filter, almost completely eliminating the need for line run-ins. This means a saving of several minutes per survey line and translates into savings of hours or even days of labour and vessel costs.
