DGPS Apparatus for detecting object under water using location information based on DGPS and method thereof

摘要

The present invention relates to an apparatus for searching an underwater object using DGPS-based position information and a method therefor. The method includes receiving first position information through a GPS signal, receiving first position correction information through a DGPS signal, correcting the first position information to the first position correction information, Generating third positional information by correcting the second positional information with previously obtained second positional correction information by using information about an altitude according to latitude, longitude and depth at a reference position, And generating an image representing the position of the object or the land in the water based on the third position information according to the reflected sound after emitting a sound wave into the water and receiving a reflection sound of the emitted sound wave.
