| Abstract: | Tunnel Segment Measurement System（TSMS） is one of the most important methods of underwater positioning and direction in pipe sinking. Firstly, this paper introduces the posi- tioning and direction theory of TSMS. Secondly, the composition of the system, data processing steps, and precision analysis are explained one by one. Thirdly, the effect of hydrology environmental factors on TSMS is analyzed in detail. Finally, the conclusion and some advises are given out. |
