Abstract
Systems and methods for providing grade control on a motor grader without the use of masts attached to the blade. Embodiments include a body angle sensor configured to detect movement of a construction machine's body, a front 3D positioning device configured to detect a geospatial position of the construction machine's body within a world space, a drawbar angle sensor configured to detect movement of the construction machine's drawbar, and a blade angle sensor configured to detect movement of the construction machine's blade. Two positions on the blade may be calculated first within a machine space and subsequently within the world space. Movement of at least one articulating connection may be caused based on the blade positions within the world space.
