摘要
Abstract
Underwater positioning technology plays an important role in deep-water operations, but because the influence of various factors in the deep water causes a certain position error, therefore the positioning accuracy influence due to various sources of error propagating through the system calculation is analyzed before using a positioning method.In the paper, distance and depth are used to carry out positioning calculation, deduce and analyze the five kinds of error caused by the system itself and the environment, including the error of measuring distance, error of speed, error of measuring time, error of sounding and error of correcting position, the basic method to reduce errors is given.关键词
