    Abstract: A DGNSS-based guidance system, wherein a rover receiver first utilizes data from a master base station transceiver, a DGNSS reference network, or some other differential source to compute a differentially corrected location to establish a reference DGNSS relationship. Using this location and data observed only at the rover, the rover computes an internal set of differential corrections, which set is stored in computer memory, updated as necessary, and applied in future times to correct observations taken by the rover. As the rover enters into areas of other base station receiver reference networks, the rover transceiver will send positional information it receives from the master base station to the new, secondary base station. The secondary base station then calibrates its own reference information using information sent from the original master base station.

    Abstract: A spray control method employs a spray vehicle including a material tank, a pump communicating with the tank, and nozzles of a spray boom communicating with the pump. A GNSS receiver mounted on the vehicle and interfaced to a controller tracks its position in relation to stored position coordinates of field boundaries separating spray zones from spray exclusion zones. The tank is activated and deactivated by the controller to retain spray of the material within the spray zones and to prevent spray of the material in the exclusion zones, by processing an offset of the spray nozzles from the receiver, the spray range of the nozzles, spray turn-on and turn-off lag times, and the velocity of the spray vehicle, all in relation to the field boundaries. An alternative embodiment individually controls spray from the nozzles by using associated valves interfaced to the controller.
