According to the ranging and positioning principle of synchronized underwater acoustic pulse, the positioning technology by underwater multi-channel GPS sonar buoy array _mine-borne 3D segment is used to track and position the rising mines in this paper. Multi-frequency underwater acoustic pulse encoded technology is used to expand transmitting period for underwater acoustic pulse. The problems are solved that measurement period is fuzzy and measurement data size is not enough. The mine-borne 3D segment designed by perception of mine states and energy –saving technology has functions on conversion of operational states and transmitting underwater acoustic signals for a long time. The simulated model for the system tracking and positioning accuracy is set up with spherical intersection positioning solution. Influences on the system positioning accuracy are predicted for the system synchronized accuracy, time-delay detection accuracy of underwater acoustic signals, GPS positioning accuracy, hydrophone position accuracy and measurement accuracy of sound velocity. The grounds are provided for the technology feasibility and the development of correlated series of measurement and control equipment.
