title = "A numerical simulation-based design of operational orbits for multiple sun-synchronous spacecraft",
abstract = "In this paper, a purely numerical simulation and optimization approach is proposed in designing a sun-synchronous orbit with additional operation requirements such as maximizing access time to a target on the ground. A high fidelity model of the Earth's gravitational attraction as well as all other perturbations are fully accounted for, and the orbit design problem is reformulated as a nonlinear optimization problem using sun-synchronicity, ground track repeatability, target access time, and ground station contact time during a certain period as cost function and/or constraint conditions. Examples show that both the sun-synchronicity and the ground-track repeatability are greatly improved compared to J2-based sun-synchronous orbits, while the orbit of multiple spacecraft can be designed in such a way that helps best utilize limited space and ground resources.",
