지자기 폭풍 영향에 의한 GPS 위치 변화량 연구
The influence of Geomagnetic Storms on GPS Positioning
- 발행 : 2004.04.01
초록
In this study, we analyzed that the geomagnetic storms in the end of October 2003 influenced a positioning of GPS permanent stations. The data that observed in total 23 permanent GPS stations are used, and did a precisely analysis every hour with GIPSY-OASIS II software to produced ITRF2000 coordinates of each stations. After that we analyzed and compared the ITRF2000 coordinates calculated every hour with public ITRF2000 results of each stations. As a result of this study, the increases of positioning errors showed well when geomagnetic storms happened and the maximum error reached about 0.80m.
