Another New Patent Hemisphere GPS Assigned Patent ALEXANDRIA, Va., Sept. 25 -- Hemisphere GPS, Calgary, Alberta, Canada, has been assigned a patent (8,271,194) developed by five co-inventors for a "method and system using GNSS phase measurements for relative positioning." The co-inventors are Michael L. Whitehead, Scottsdale, Ariz., Steven R. Miller, Scottsdale, Ariz., John A. McClure, Scottsdale, Ariz., Cary Davis, Cave Creek, Ariz., and Walter J. Feller, Airdrie, Calif.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method for locating GNSS-defined points, distances, directional attitudes and closed geometric shapes includes the steps of providing a base with a base GNSS antenna and providing a rover with a rover GNSS antenna and receiver. The receiver is connected to the rover GNSS antenna and is connected to the base GNSS antenna by an RF cable. The receiver thereby simultaneously processes signals received at the antennas. The method includes determining a vector directional arrow from the differential positions of the antennas and calculating a distance between the antennas, which can be sequentially chained together for determining a cumulative distance in a "digital tape measure" mode of operation. A localized RTK surveying method uses the rover antenna for determining relative or absolute point locations. A system includes a base with an antenna, a rover with an antenna and a receiver, with the receiver being connected to the antennas. A processor is provided for computing positions, directional vectors, areas and other related tasks."
