DETERMINING A CRANE TILT ANGLE

摘要

In a method for determining a tilt angle of a crane, a portion of the crane is rotated about a pivot point. A Global Navigation Satellite System (GNSS) receiver antenna is disposed on the portion of said crane. At least three locations of the GNSS receiver antenna are determined by a GNSS receiver in a geo-referenced coordinate system during the rotating. A tilt angle of the crane based on the at least three locations of said GNSS receiver antenna is determined by a processor.
