The invention discloses a submarine pipe cable burying underwater positioning system and a working method thereof and relates to the field of submarine pipe cable burying. When a submarine pipe cable burying plough works, the submarine pipe cable burying plough is invisible, and an effective method for obtaining the posture of the burying plough in real time is lacked. The system comprises a submarine cable burying workboat, a burying plough, a surveying boat, an ultra-short baseline transducer and a plurality of ultra-short baseline beacons arranged on the burying plough, an object coordinate system is set on the burying plough, the position vector of the ultra-short baseline beacon under the object coordinate system and the position vector of the submarine cable under the object coordinate system are determined according to the structural shape and size of the burying plough, and different burying depths correspond to different submarine cable conduit positions; during operation, the ultra-short baseline tr
