Abstract

GPS (Global Positioning System) is currently used widely in the ground section, such as surveying, mapping, geodesy, geophysics, the aviation section, such as aerial navigation and aerial photography, the sea section, including ship navigation and bathymetry, and space section, such as the satellite orbit and Earth's orbit. On the other hand, its use is limited due to the professional knowledge and expense to process the data for precise analysis. As a result, a web-based data processing solution for precise point positioning using GPS data was developed by c# for non-specialized people to process easily. In addition, the crustal movement speed of Korea after an earthquake was calculated to be an average of 30mm/year for each CORS, suggesting that it is possible to monitor crustal movement.

현재 GPS는 측량 및 지도제작, 측지, 지구물리와 같은 지상부문, 항공기 항법, 항공사진 촬영과 같은 공중부문, 선박의 항법, 수심측량과 같은 해상부문, 위성 궤도, 지구궤도와 같은 우주부문 등 다양한 분야에서 폭넓게 활용되고 있다. 그러나 넓은 활용분야에 비해 정밀 해석의 자료처리를 위해서는 전문지식뿐만 아니라 비용적인 문제로 인해 활용에 제약이 있다. 이에 본 연구에서는 전문지식이 없는 사용자도 GPS 데이터를 이용하여 손쉽게 정밀절대측위 성과를 얻을 수 있도록 C#을 이용하여 웹기반의 GPS 자료처리 솔루션을 개발하였다. 또한, 개발된 솔루션을 이용하여 우리나라가 일본 지진 이후 상시관측소 별로 평균 30mm/year의 지각변동이 나타남을 산출하고, 기존 지각변동 속도와 비교함으로써 지각변위속도 모니터링의 활용가능성을 제시하였다.
