해양탐사를 위한 DGPS(Differential GPS) 자료의 후처리 시스템 개발

초록

The purpose of this paper is to introduce the development of a DGPS postprocessing system for the marine applications. In the marine surveying, the precise position of a surveyor is very important for the marine survey to merge various types of surveyed data. In this work implemented is a system to acquire the surveyor's precise position and to display its track by using the offset distance of the known position of a reference station. At first, this paper describes the main error sources of GPS, then introduces the procedures of developing of the DGPS postprocessing system.
