A global navigation satellite system (GNSS) based control system is provided for positioning a working component relative to a work surface. Inertial measurement unit (IMU) sensors, such as accelerometers and gyroscopes, are mounted on the working component and provide positioning signals to a control compute engine. A method of positioning a working component relative to a work surface using GNSS-based positioning signals is also disclosed.
