We propose a method for optimizing satellite constellations and a series of process strategies to achieve the desired revisit performance for each target in the area of interest. Using a repeat ground track orbit of periodic characteristics, a tailored regional-satellite-constellation method is developed to achieve the desired revisit performance for each target. The study consists of four parts representing four programs: finding orbit elements through optimization techniques, producing an access matrix between targets and satellites, deriving the number of satellites for each target for the desired revisit performance, and deploying satellite groups by minimizing the orbital plane. Then, the superiority of this optimization method is verified through numerical comparisons and contour distributions for revisit performance compared with the existing conventional Walker method. |
