N2 - Underwater navigation that relies solely on dead reckoning suffers from unbounded position error growth. In traditional positioning method based on TDOA, usual interference from multipath reflections and background noise lead to the choice of some fault correlation peaks and low SNR. In the paper, the combination of LBL and Doppler difference of an AUV will be expected to enable survey accuracy at any water depth where the position of an underwater acoustic transmitter equipped on the moving platform can be determined. And based on pattern time delay shift coding pulse, frequency estimation of Doppler shift in LBL method could be described with Doppler effects from AUV moving. Thus, with the intersection of two contours of Doppler difference, the positioning solution of AUV and the relative trial results could be finished and verified.
