| Abstract: | In the underwater topography surveying near sea or lake, GPS is widely used with the echo sounder,the positioning precision of GPS in the underwater topography surveying is impacted by such factors as GPS installment, post processing of captured data. Installment mode, reliability analysis of captured data and all kinds of real-time diverse modify are discussed in the paper. |
