Crane boom pointing angle determination
First Claim
1. A method for determining a working arm pointing angle of a crane relative to a reference direction, said method comprising:
- disposing a Global Navigation Satellite System (GNSS) receiver antenna on a point along a boom assembly of said crane configured to pivot about a pivot point;
receiving a location of said pivot point;
rotating a working arm of said crane about said pivot point to point in a current direction;
determining a current location of said GNSS receiver antenna; and
determining a current working arm pointing angle relative to a reference direction for said current direction of said working arm based on said current location of said GNSS receiver antenna and said location of said pivot point.

Abstract
Methods and systems are disclosed for determining a working arm point angle of the crane. A Global Navigation Satellite System (GNSS) receiver antenna is disposed on a point along a boom assembly of the crane configured to pivot about a pivot point. A location of the pivot point is received. A working arm of the crane is rotated about the pivot point to point in a current direction. A current location of the GNSS receiver antenna is determined. A current working arm pointing angle relative to a reference direction for the current direction of the working arm is determined based on the current location of the GNSS receiver antenna and the location of the pivot point.
