Abstract:
1. A system for determining three-dimensional position defined by three coordinates, comprising a laser transmitter that projects at least one laser beam that rotates about a generally vertical axis, a GNSS receiver for determining position, the GNSS receiver having a GNSS antenna, an optical sensor for receiving the laser beam, said optical sensor being in fixed position with respect to the phase center of said GNSS antenna, and a device receiving signals from the GNSS receiver and signals from the optical sensor to determine and store the three-dimensional position defined by three coordinates of the transmitter from said signals, said device thereafter utilizing signals received from the optical sensor and from the GNSS receiver to determine the three-dimensional position defined by three coordinates of said GNSS receiver, each of said three coordinates defining the three-dimensional position of said transmitter and the three-dimensional position of said GNSS receiver being determined by signals from both of said GNSS receiver and said optical sensor.
