Abstract:

A low orbit constellation is designed based on the revisiting cycle in order to realize the intermittent reconnaissance to the global region. Firstly, a constellation design model is built based on the orbit height and inclination of the nearly circular recursive orbit. The single orbit plane and triple orbit plane parameters,which satisfy earth reconnaissance mission, are determined. Then the complex shape optimization method is selected to optimize the two kinds of constellation. Considering the cover performance as the objective function, the orbit inclination, longitude of the ascending node, and inter-satellite phase are selected as optimization variables. Finally, constellation performance is evaluated using the coverage gap number, coverage percentage and average response time. It is shown that the constellation performance of the triple orbit plane is superior to that of single orbit plane, and can fulfill the earth reconnaissance objective.
