In this paper, the cable surveying equipment including the underwater vehicle, TSS440 cable surveying system, differential posi- tioning system and underwater positioning system, and the surveying process are introduced. Field application shows that the use of un- derwater vehicles can help overcome the difficulties in Liaodong Bay, such as the shallow and turbid water, and the effect of water flow. The successful mapping of the position coordinates and maps of submarine cables guarantee
