The paper discusses guide survey system in long distance curved pipe jacking, presents a three-dimensional datum transformation model to determine the orientation of jacking pipe，The unitary principle and the new navigating method are introduced and the methods accuracy and variance are analyzed. The intelligence guide system is carried through easily associate with total station. The mathematical model, the operation principle, the hardware realization of extra long pipe jacking automatic guidance are introduced. Practice shows that all the reference points are used more efficiently in the new model than in the general model, and the surveying and navigating system gets enormous time-saving against conventional methods
