    摘要: A GPS (Global Positioning System) aircraft guidance system for use with circular cultivated agriculture fields. The system of the present invention includes a GPS receiver adapted to determine a present position, ground track, and ground speed of an aircraft. The GPS receiver is also adapted to store a configuration of a circular cultivated agricultural field and to compute a desired flight path for achieving an optimal coverage of the field. Deviations of the aircraft from the desired flight path are also determined. The GPS receiver is further adapted to generate a dispense signal which indicates when to dispense agricultural chemicals from the aircraft. A guidance indicator is coupled to the GPS receiver for providing guidance information to the pilot. The guidance indicator is adapted to indicate the aircraft's deviation from the desired flight path and indicate whether the dispense signal is asserted. This information aids the pilot in maintaining the desired flight path and achieving the optimal coverage of the circular cultivated agricultural field.

    摘要: Real time kinematic (RTK) global positioning system (GPS) technology is integrated with precision farming methodologies to provide highly accurate seeding, cultivating, planting and/or harvesting operations. RTK GPS systems are used to control fully or semi-autonomous vehicles in these operations and may allow for precision planting of seeds (e.g., from a seeder equipped with an RTK GPS receiver and related equipment) and/or precision weed removal (e.g., using a vehicle fitted with weed eradication mechanisms such as augers and/or herbicide sprayers). Crop specific fertilizer/pesticide application is also enabled through the use of centimeter-level accurate positioning techniques.

    摘要: A digital subscriber controller having a number of analog ports and digital ports which can be programmed via an external microprocessor to establish time-division multiplexed bidirectional data paths between three subscriber-selected ports designated as "sources" and three subscriber-selected ports designated as "destinations". Among the ports is a line-interface port having two 64 kilobit-per-second voice/data channels and a 16 kilobit-per-second data control channel. Among the digital ports is a three-channel serial interface port and a two-channel microprocessor interface port. An analog port is also provided at which a variety of audio transducers may be connected. The controller includes a line interface unit, a data link controller which processes data channel information present at the line interface unit, a main audio processor, a microprocessor interface, and a multiplexer which establishes the data paths selected by the subscriber.
