US Patent:

7054731, May 30, 2006
Filed:

Aug 29, 2003
Appl. No.:

10/652454
Inventors:

Arthur F. Lange - Sunnyvale CA, US
Timothy J. Funk - San Jose CA, US
Assignee:

Trimble Navigation Limited - Sunnyvale CA
International Classification:

G06F 19/00
US Classification:

701 50, 701 26, 701213, 172 45
Abstract:

An apparatus and method using GPS for dynamically adjusting side-to-side positioning of a farm implement along a geographical path. The apparatus includes a global positioning system (GPS) antenna disposed on the farm implement, a GPS receiver coupled to the GPS antenna for determining a location of the GPS antenna, and a dual guidance computer for comparing the location to stored geographical coordinates of a desired path or providing a guide signal for offsetting the lateral position of an adjustable hitch or angling a wheel or ground rudder in a steerable implement for guiding the implement along the path; and a range extent signal for maintaining the offset of the hitch or steering angle of the implement within its dynamic range.
