System for guiding a farm implement between swaths
First Claim
Patent Images
1. A farming apparatus for guiding an implement in a turn between swaths, comprising:
- a GPS receiver for determining a GPS position for a farm implement propelled by a powered vehicle; and
a turn computer including a turn path calculator configured to determine a turn path based on an end position of a first swath and a start position of a second swath; and
a GPS cross track error (XTE) calculator configured to compare said GPS position to said turn path for providing a GPS XTE, said GPS XTE for steering said vehicle along said turn path.

Abstract
An apparatus, method and tangible medium using GPS for guiding a farm implement along a turn path between swaths. The apparatus includes a GPS receiver and a turn computer. The turn computer calculates or stores a turn path between swaths, calibrates GPS positions to a swath end position and uses the calibrated GPS positions to guide the implement along the turn path to the start of the next swath. A steering wheel autopilot may be included to steer a powered vehicle according to a cross track error between the calibrated GPS positions and the turn path.
