Gnss and optical guidance and machine control

A steering system for a vehicle or implement, comprising:

• one or more processors to:
• send one or more steering control commands to a steering controller to steer the vehicle or implement;
• determine a position and heading of the vehicle or implement in relation to a desired track;
• calculate one or more calibration errors based on the determined position and heading of the vehicle or implement in relation to the desired track,
• determine one or more calibration values based on the one or more calibration errors;
• generate additional steering control commands based on the calibration values;
• and
• send the additional steering control commands to the steering controller to steer the vehicle or implement.

A steering system, comprising:

• a controller to:
• send one or more steering control commands to a steering control mechanism to steer an agricultural vehicle or implement;
• receive sensor data indicating a position, heading, and rate-of-turn of the agricultural vehicle or implement;
• calibrate the steering control mechanism based on the sensor data;
• and
• send one or more additional steering control commands to the calibrated steering control mechanism to steer the agricultural vehicle or implement.

A method for operating an agricultural vehicle, comprising:

• using one or more steering control commands to steer the agricultural vehicle on a desired track;
• receiving data from one or more sensors indicating a response by the agricultural vehicle to the one or more steering control commands;
• determining a deviation of the agricultural vehicle from the desired track based on the data from one or more sensors indicating the response by the agricultural vehicle to the one or more steering control commands;
• deriving one or more calibration values based on the deviation of the agricultural vehicle;
• generating additional steering control commands based on the one or more calibration values;
• and
• using the additional steering control commands to steer the agricultural vehicle on the desired track.
