Abstract
A guidance system for directing a towed implement comprising: a first DGPS system, comprising an antenna located on a towing vehicle in operable communication with a receiver; a second DGPS system comprising another antenna located on a towed implement in operable communication with another receiver; a receiver configured to receive differential correctors from a reference GPS system; a controller in operable communication with the first DGPS system, the second DGPS system, and the receiver, the controller generating a first steering command; and a steering mechanism in operable communication with the controller and configured to direct a towed implement based on the first steering command provided thereto.
Claims14
A guidance system for directing a towed implement comprising:
- a first DGPS system, comprising an antenna located on a towing vehicle in operable communication with a receiver;
- a second DGPS system comprising another antenna located on a towed implement in operable communication with another receiver;
- a receiver configured to receive differential correctors from a reference GPS system;
- a controller in operable communication with said first DGPS system, said second DGPS system, and said receiver, said controller generating a first steering command;
- a steering mechanism on a towed implement in operable communication with said controller and configured to direct a towed implement based on said first steering command provided thereto.
A method for steering a towed implement comprising:
- generating a differential corrector at a reference DGPS receiver and transmitting said differential corrector of a towing vehicle;
- receiving said differential corrector;
- receiving a first position from a first DGPS system corresponding to a position or said towing vehicle;
- receiving a second position from a second DGPS system corresponding to a position or said towed implement;
- computing a corrected position for said towed implement;
- and
- for each desired swath:
- computing a desired track and cross track error
- computing a steering correction for said towed implement;
- and
- generating a first steering command to a first steering mechanism on said towed implement.
