Automatic guided vehicles（AGVs）which adopt magnetic nail navigation and positioning technologies face limitations in their applications in container terminals arranged in parallel in yards. Taking the Nansha Phase IV project of automated container terminals in Guangzhou Port as an example，this paper analyzes the technical characteristics and advantages of new intelligent guided vehicles（IGVs）which are equipped with positioning technologies featured with satellite and inertia navigation and multiple sensor fusion，and it expounds on the main design points of terminal infrastructure related to positioning and navigation，energy supplement，and maintenance of IGVs. Therefore，the paper can provide a reference for the design and construction of similar automated container terminals.
