Abstract: To meet the requirements during project of sub-sea long-distance pipe-jacking at Shantou,an automatic surveying system with independent intellectual property right was proposed and implemented,which is suitable for super long-distance pipe-jacking project.The whole surveying during project is run automatically under control of computer without manual intervention.If there are three total stations in this system,it is able to finish a complete surveying in 3 minutes.The precision of this system is centimeter-level.The successful application of this system and perfect completion of the project of long-distance pipe-jacking at Shantou indicate that this system has advantages of high reliabilities,stable operation,rapid response,and high accuracy.
