  • Abstract The main purpose of this research is to build up the geometric correction model for EROS A satellite. The major works include orbit adjustment and orthorectification. The orbit modeling will be done by using the onboard data and GCPs (Ground Control Points); while the orthorectification will be done by using the precise orbit and DTM (Digital Terrain Model).
    Both Bundle Adjustment and Onboard Data Correction Model will be applied to do the orbit adjustment. In the Bundle Adjustment, we assume the exterior parameters as polynomial functions. To stabilize the system, we have added weight matrix for the parameters estimates; and to fine tune the orbit, we use the Least Squares Filtering technique. In the Onboard Data Correction Model, the high correlation between the satellite position and satellite attitude, we fix the satellite attitude to correct the satellite position, the orientation parameters is initialized from the onboard data. We perform the correction for on-board parameters as polynomial functions. Then, by using a small number of ground control points, we adjust the satellite’s orbit accurately. Finally, we use the Least Squares Filtering technique to fine tune the orbit. 
    In orthorectification, we use the indirect method to generate the orthoimage. The indirect method projects the 3D object point on to 2D image space. In order to accelerate the computation, we divide the image into a number of tiles in the orthographic correction.
    Experimental results indicate that the proposed scheme may reach an accuracy of better than two pixels in the image scale for an image sampled with an asynchronous ratio of 13.
