Abstract: A method and system for determining an alignment error between sensors mounted to a machine is disclosed. The method may include calculating a first orientation value based on a signal received from a first sensor. The method may further include calculating a second orientation value based on a signal received from a second sensor. The method may further include calculating an alignment error between the first sensor and the second sensor based on a difference between the first orientation value and the second orientation value.

Abstract: A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor of a machine are disclosed. The method may include calculating a first elevation value of an implement of the machine. The method may include calculating a second elevation value of a ground-engaging device of the machine. The method may include, in response to determining that the machine is spreading, adjusting the second elevation value based on a compaction factor to determine an adjusted second elevation value. The method may further include determining a first elevation difference value based on a difference between the first elevation value and the adjusted second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference.

Abstract: A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor of a machine are disclosed. The method may include calculating a first elevation value of an implement of the machine in a gravity reference frame of the machine. The method may further include calculating a second elevation value of a ground-engaging device of the machine in the gravity reference frame of the machine. The method may further include determining a difference between the first elevation value and the second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference.
