【正文】 tain container with container ID and its position will be sent via radio to an RTG Thirdly the RTG operator will drive the RTG t finish the operation； Finally， the pletion of the operation will be acknowledged by the operator in that sequence, some potential problem may occur: positions of the RTGS are not clearly indicated and RTG having optimal path can’t be selected； the cost then increases； 2. there is no monitoring of the container， then the container may be misplaced： 3. manual interference for acknowledgement is required. However the whole operation could be made in a closed loop by puters without any potential mistake involved by equipping RTGs with GPS. Also the efficiency could be raised greatly See the charts for details. Technical data of the GPS from ZPMC 1． System configuration 1). The whole project of RTGs will be equipped with one GPS base station it consists of a dual—frequency GPS receiver and a modulating radio transmitter. The function of the base station is to send correction data of GPS position to each crane station. 2). Each crane will be equipped with a GPS rover station which consists of two GPS receivers and a mon radio receiver. This rover station will check the current position of the RTG with a precision at centimeter level. The position signal will be sent to the main PC to be dealt with for functions of container position and auto steering control etc. The whole GPS system is pact, simple and independent and it is easy to be 1nstalled on RTG without imposing any influence on the mechanical design. 2.
