For geometric correction of pushbroom satellite images, mathematical models are required, which can model the dynamic geometry of image.
For high resolution satellite images, because the various reasons (for example: security problems), information about satellite location and satellite position (satellite ephemeris) is not available. Therefore, using of independent mathematical models from satellite ephemeris is essential (for instance: Rational Functions Model).

In this paper, geometric accuracy of three sensor’s images has been tested by several mathematical models for extracting the 2D and 3D geometric information. The results indicate:
