It was aimed to improve positioning algorithm of long range USBL under the deepwater condition for the sake of higher positioning precision. After discussing the theory of positioning of USBL and conventional algorithm, a simple and convenient new positioning algorithm which could be used for random distributed velocity of sound was proposed. The simulation results prove its correctness. Key words: USBL; new algorithm; positioning precisi
