METHOD AND SYSTEM FOR DETERMINING DISPLACEMENT OF AN ANCHOR

摘要

A method for determining a displacement of an anchor comprises the steps of: determining an initial position of the anchor; determining a displacement of the anchor by measuring anchor acceleration values, measuring at least one further physical quantity associated with the anchoring, deciding whether the anchor is at rest or in motion, wherein a value of the further physical quantity is taken into account in the decision, and integrating the acceleration values twice over time during intervals when the anchor is deemed to be in motion.
