Abstract: An automated steering device is provided usable in conjunction with power equipment machines. By way of example, the automated steering device can provide user-assisted steering for a power equipment machine to maintain tight parallel paths. The user-assisted steering can be defined relative to an initial vector traversed through user directed operation of the power equipment machine, independent of or at least in part independent of a predefined area of operation for the power equipment machine. Position location data refined by local terrestrial positioning system correction devices, or onboard rotational correction devices can be provided to obtain high positioning accuracy, and minimal path deviation. As a result, highly accurate pathing can be provided by way of the disclosed automated steering devices.

Abstract: A method for correcting real-time kinematic (RTK) global positioning data for a machine. The method comprises receiving first real-time kinematic (RTK) position location data for a power equipment device defining a first position location for the power equipment device and acquiring a fix RTK data status for the first RTK position location data. The method further comprises receiving second RTK position location data for the power equipment device defining a second position location for the power equipment device and acquiring the fix RTK data status for the second RTK position location data. The method further comprises determining a heading and speed of the power equipment device from the first and second RTK position location data. The method further comprises receiving third RTK position location data for the power equipment device defining a third position location for the power equipment device; acquiring a float RTK data status for the third RTK position location data; determining an expected third position location for the power equipment device; and determining a correction factor at least in part from the expected third position location of the power equipment device and utilizing the correction factor to adjust subsequent RTK position location data for the power equipment device having the float RTK data status.
