| dc.description.abstract | GPS측량에 있어서 GPS위성의 궤도정보는 측량정확도에 영향을 미치는 요소중의 하나이며, GPS측량을 위해 제공되는 위성궤도정보에는 방송력과 정밀력, IGS신속력과 IGS초신속력이 있다. 본 연구에서는 경상북도 울진지역에 연구대상지역을 선정하고 GPS관측을 실시하였으며, 74개의 기선에 대하여 TGO를 이용하여 방송력과 정밀력을 사용하여 기선해석을 실시하고 그 결과를 비교하였다. 비교결과 방송력과 정밀력에 의한 차이는 거의 없는 것으로 나타났으며, 기선길이의 상대정밀도에 있어서 방송력의 경우 0.708ppm, 정밀력의 경우 0.706ppm으로 나타나 정밀력을 사용한 결과가 약간 우수한 것으로 나타났다. | - |
| dc.description.abstract | The orbit ephemeris of Global Positioning System(GPS) is one element to determine the surveying accuracy and there are broadcasting ephemeris and precise ephemeris, IGS rapid orbit and IGS ultra rapid orbit in the orbit ephemeris of GPS. In this study, test area was selected in Uljin, Kyungsanbukdo and GPS surveying was accomplished at 37 points in the test area. Then baseline solution was done on 74 baseline using broadcasting ephemeris and precise ephemeris and analysis by TGO and the results were compared. Comparison results were showed that there were nearly no difference between the two results but in case of relative precision of the baseline, it was slightly better the baseline results of precise ephemeris which showed 0.706ppm than the baseline results of broadcasting ephemeris which showed 0.708ppm. | - |
