A system and method of controlling an earth moving implement of a machine is disclosed. The method may include receiving a pitch rate of the machine in a body reference frame and determining a roll of the machine. The method may further include determining a turning rate of the machine and calculating a pitch rate of the machine in a gravity reference frame based on the pitch rate of the machine in the body reference frame, the roll of the machine, and the turning rate of the machine. The method may further include controlling the earth moving implement based on the pitch rate of the machine in the gravity reference frame.
