                                Processing User Service (OPUS) was used to
                                compute the coordinates and Horizontal Time
                                Dependent Positioning (HTDP) was used to

     Additional Information   : The new antenna was installed on the same mount as
                                the previous antenna.  The horizontal position should
				be very near the previous position.  However, the vertical
				position will change by the difference in the heights of the
				antennas.
				Position of new antenna has now been possted.
