National Geographical Organization Scientific- Research Quarterly of Geographical Data (SEPEHR) 2588-3860 17 68 2009 01 20 Examining the Quality of the IMU Observational Parameters and the Determination of its Drift Value Examining the Quality of the IMU Observational Parameters and the Determination of its Drift Value 41 44 27450 FA Hadi Babapour Ahmad Javaheri Ali Mohammadpour Journal Article 2008 08 18 Given the existing sanctions on the use of new technologies in the field of photogrammetry and remote sensing, and given that the Geographic Organization has one of the most advanced digital cameras in the world, the importance of localization in the field of production and self-sufficiency is increasingly felt. The installation of digital camera on a plane was one of the problems which, thankfully, was solved by the experts of the Geographic Organization. In the next step, the status parameters (translation and rotation parameters) of the digital camera should be determined relative to the two GPS and INS systems. Therefore, the first digital images were obtained by designing control points and appropriate flight paths over a test area. Finally, the magnitude of rotation parameter (Bore Sight), magnitude of shift (GPS Drift) and also the effect of Self-Calibration equations in final results and the determination of the magnitude of extra parameters were determined.
