摘要:OrbView-3 is in relation to the other very high resolution satellites like IKONOS and QuickBird a low cost system. This does not mean; the accuracy of the object point determination must be less than based on the other. Even because of the not so expensive imaging system, an edge analysis did not indicate a lower resolution than the ground sampling distance (GSD). An OrbView-3 stereo model has been oriented and checked for geometric property. The orientation is possible by means of the sensor related rational polynomial functions which have to be improved by means of control points but also by other methods like 3D-affine transformation and direct linear transformation (DLT). The 3D-affine transformation and the DLT do not use any available pre-information about the sensor geometry, so they have to be based on a higher number of three-dimensional well distributed control points. The different orientation methods are compared and the discrepancies at the control points have been analysed for remaining systematic errors. A covariance analysis and the relative accuracy do indicate the possible accuracy if any systematic effect has been taken into account
