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 GNSS receiver 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.

Abstract: A method and system for controlling access to restricted sectors in airspace. The method includes creating a multi-dimensional map of airspace, overlaying a sector having boundaries onto the map, wherein the sector contains a restricted flight zone and a buffer zone monitoring the flight of an unmanned aerial vehicle (UAV), sending a command to the UAV if the UAV enters the buffer zone; and generating a response if the UAV does not leave the sector based on the command.
