An orbit analysis for performing remote sensing from the international space station

The International Space Station (ISS) is evaluated on its suitability as an Earth remote sensing platform from an astrodynamics perspective. The structure of the ISS combined with the effects of drag cause variations in its altitude. To better grasp the consequences of the erratic orbit on Earth remote sensing, this paper models the orbit of the ISS while taking into account viewing restrictions including lighting conditions, docking events, and station maneuvers. Comparisons between the actual orbit and NASA trajectory predictions are reviewed for mission planning and feasibility purposes.
