Abstract:Yangshan Deepwater Port phase IV project of Shanghai International Shipping Center is positioned in automated container terminal,its AGV navigation system is based on transponder technique.Combined with engineering practice,the paper focuses on the positioning method of transponder for navigation system,and an analytical method of static control under large range conditions is proposed.The positioning uses GPS static control and total station polar coordinates,which is proved to be able to meet the precision of transponder installation for AGV navigation by analysis and calculation.
