Abstract

Currently‚ considering the wide range of space applications‚ missions aimed at regional coverage are among the prominent options. This study introduces two different analytical algorithms to find the optimal orbital inclination based on the maximum regional coverage criterion for a satellite in a low Earth circular orbit. For instance‚ for a satellite at an altitude of 700 kilometers with a minimum elevation angle of 20 degrees (corresponding to FOV of 115.6 degrees)‚ the optimal orbital inclination to achieve maximum geometric coverage in Iran's target region is determined to be 39 degrees using both analytical algorithms. The results are validated through simulation in STK software and are analyzed and compared. This research‚ based on the analysis of the relationship between orbital inclination angle and regional coverage‚ provides valuable information to satellite designers and researchers. The findings can be used to improve the performance and efficiency of satellites in low Earth circular orbits to meet various regional needs.
