한국 연안의 DGPS망 구축을 위한 장기갑기준국으로부터의 DGPS 측정에 관한 연구
A Study on DGPS Test Using Chaggi-gap Reference Station to Construct DGPS Network in Korea Coast
초록
The test transimissionof DGPS correction data has been carried out since early 1996. The data has been sent from marine radiobeacon station at Changgi Gap Ligthouse. It was the first test brosdcast of DGPS correction data based on midium frequency of marine radiobeacon where transmission power and rate are 300W and 100bps respectively. However, there has not been any scientific study on the characteristic of the accuracy of a marine DGPS/radiobeacon. Accordingly. this paper investigates the accuracy of the system, which is currently operating in 310KHz. As a result , planned 8 reference station and coverage verified that the differential positioning accuray using themarine radiobeacon is sufficient to ensure the safetyof marine activities around the coast of Korea(position error of distance 107NM at reference station was about10m(drms)).
