摘要：This paper presents accuracy and stability of orbit modeling. Orbit modeling is carried out using the stereo strips which were taken by SPOT-3 satellite, a large number of GCPs(Ground control points) and orbit-attitude sensor model as a rigorous sensor model. To verify the accuracy and stability of orbit modeling, we analyzed orbit model error against whole strip and absolute orientation accuracy of orbit-attitude models established separately. Furthermore, For Additional verification of orbit model, we generated DEMs(Digital Elevation Level) using results of orbit modeling. On all of the tests, we obtained three-dimensional object-space coordinates have high accuracy and stability against whole strip. In this study, we used orbit modeling proposed by Kim(2005) focused on the strip images which have a same orbital characterization. That's useful for inaccessible area analyzing. In the future, if we apply that orbit modeling for the inaccessible area, we will able to acquired three-dimensional object-space coordinates about 420km in distance. This reseach results will help people to analyze inaccessible area without direct contact of the area
