Satellite Constellation Orbit Design Optimization with Combined Genetic Algorithm and Semianalytical Approach

Figure 27

Satellites’ full ground track (a) and close-up (b) for a solution in Case with best maximum revisit time at 3 hours and 24 minutes and 32% area coverage. Red line: ground track of sat #1, pink line: ground track of sat #2, and blue line: ground track of sat #3. Red star: area covered by sat #1 and blue triangle: area covered by sat #3. In this case, area covered by satellites #1 and #2 is similar, so the paths are stacked on top of each other.
