초록

최근 상시관측소와 네트워크 기반 RTK를 활용하여 GPS/INS를 해석하고 이를 통해 항공사진측량에 필요한 외부표정요소를 획득하는 방법은 널리 알려져 있다. 본 연구에서는 외부표정요소를 계산함에 있어 지상기준국을 활용하는 방법과 상시관측소과 방송력 및 IGS 정밀력을 결합해 SmartBase를 이용하는 방법, 각각의 상시관측소를 이용하는 방법을 비교하였으며, 지상기준국으로 계산한 성과를 기준으로 외부표정요소의 잔차를 계산하였다. 그 결과 SmartBase를 활용하여 외부표정요소를 획득한 경우는 상시관측소만을 활용한 경우보다 X, Y, K에서 더 높은 정확도를 획득할 수 있었다. 또한 지상기준국을 중심으로 상시관측소의 거리와 방향이 외부표정요소에 영향을 미치며, 항공사진 코스에 따라 각각 다른 형태의 잔차가 나타남을 알 수 있었다.

Recently, it is a pretty well known way to compute GPS/INS using Continuously Operating Reference Station (CORS) and Network-based RTK for obtaining Exterior Orientation (EO) parameters of aerial photogrammetry. In this study, it is way to compute Exterior Orientation (EO) parameters using ground base stations, using Continuously Operating Reference Station (CORS) broadcast orbits and International GNSS Service (IGS) rapid orbits. And the residuals of Exterior Orientation (EO) parameters were computed based on the results of ground base station. As a result, the case of using SmartBase to obtain Exterior Orientation (EO) parameters was showed the high accuracy of X, Y, K more than using Continuously Operating Reference Station (CORS) of National Geographic Information Institute (NGII). Also, distance and direction of Continuously Operating Reference Station (CORS) of National Geographic Information Institute (NGII) from ground base station affected Exterior Orientation (EO) parameters. And different forms of residuals were shown according to the aerial photo courses.
