【正文】 中文 2295 字 Application of GPS on Yard Cranes Abstract： GPS is a satellite navigation and positioning system developed by America. Through 24 satellites evenly distributed in the air， the system ensures that positioning information could be well received all over the world at any time. Since the system was put into operation， it has been widely applied to uses such as oil surveying， ship and aircraft navigation， construction positioning and military operation. Key Words: GPS , cranes, Port Machinery GPS is a satellite navigation and positioning system developed by America. Through 24 satellites evenly distributed in the air， the system ensures that positioning information could be well received all over the world at any time. Since the system was put into operation， it has been widely applied to uses such as oil surveying， ship and aircraft navigation， construction positioning and military operation. ZPMC began the study of GPS application on yard cranes two years ago with the purpose of providing the RTG with functions such as reliable straight traveling of gantry and automatic container management like RMG (Rail Mounted Crane) while keeping the RTG of its flexibility on yard changing(through longitudinal traveling). The GPS products developed by ZPMC have a positioning accuracy a round177。15mm and could be widely applied on yard cranes for functions like gantry autosteering，gantry autotraveling and automatic container management More than 50 sets of GPS products have been operating on ports in Hong Kong， Oman and Shanghai. Application of GPS on Yard Cranes Application of GPS on Yard Cranes It has been long known that the RTG， due to its ability of changing operation yard easily via wheel turning and longitudinal travel， is the favorite choice of many ports when ordering new equipment Due to the fact that RTG has no fixed rail however， the function of the gantry steering and position tracking are not well solved，which brings the following drawback： steering work is being more difficult following that the RTG is being large r and quicker； growth of international tra
