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。 then the performance of the crane will decrease. With position monitoring on both seaside and land side Synchronous control could be used to remove this problem; 7. AGV navigation traveling of AGV could be remotely controlled with the help from GPS data; 8. Position monitoring for container truck the GPS product could also be applied on container trucks for position monitoring. Application of GPS on container operation management The traditional mode of container operation in many ports is: firstly, in the operation department, information on the containers to be operated would be stored in a main
