{{Short description|Concept in civil engineering}} In civil engineering, '''machine control''' is used to accurately position earthwork machinery based on 3D design models and GPS systems, and thus aid machine operators to e.g. control the position of a road grader's blade.<ref name="heikkila">{{citation |last1=Heikkilä |first1=Rauno |last2=Jaakkola |first2=Mika |year=2003 |title=Intelligent Road Construction Site - Development of Automation into total Working Process of Finnish Road Construction |journal=2003 Proceedings of the 20th ISARC |place=Eindhoven, Holland |url=http://www.iaarc.org/publications/fulltext/isarc2003-61.pdf |format=PDF |accessdate=November 8, 2010}}</ref> Many machine control systems utilize the Real Time Kinematic (RTK) system to improve the positioning accuracy.
There are six dominant manufacturers of machine control systems: [https://www.makin3d.com Makin], [https://www.idig-system.com/ iDig], Leica Geosystems, MOBA Mobile Automation AG, Trimble Navigation Limited, Unicontrol and Topcon Positioning Systems.
