“…A thorough analysis of the long-term dynamics of SD geocentric trajectories is due to Zhao et al [92], who refined the previous works by Colombo and McInnes [89,90,91] by modeling the SRP force, the atmospheric drag and Earth's sectorial gravitational harmonics up to degree two and order two. Similar to the previous works, their main assumptions [92] are that the atmosphere rotation and the Earth's axis tilt are both neglected, the SD orbit lies on the ecliptic plane, and the SD maintains a Sun-facing attitude.…”

“…The complete expressions of da/dt, de/dt and dω/dt are here omitted for the sake of conciseness, but may be found in Ref. [92]. When these expressions for the time derivatives are integrated, the result is ∆a ∆a SRP + ∆a drag , ∆e ∆e SRP + ∆e drag , ∆ω ∆ω SRP + ∆ω grav (42) where the subscript "grav" accounts for all the zonal, tesseral, and sectorial gravitational harmonics, which affect the time history of the argument of perigee only.…”

“…A very promising geocentric mission application for SDs has been proposed by Colombo and McInnes [89,90] and Zhao et al [92], who discussed the equilibrium condition of femtosatellite orbits. Indeed, with the current technology level, the propulsive acceleration and the orbital perturbations could be exploited to guarantee a variation of the argument of perigee equal to the angular displacement of the Earth along its heliocentric orbit, while maintaining the semimajor axis and the orbital eccentricity both constant [89,90,92]. Starting from Eqs.…”

In order to investigate coordinated orbit control problem for large-scale cluster flight spacecraft, a distributed orbital containment control algorithm is proposed for spacecraft cluster flight system with multiple leaders. At first, a general distributed orbital containment control strategy for largescale cluster spacecraft system is given, so that all followers are driven to the convex hull formed by leaders. Then the constraints of convergence and convergence rate of cluster spacecraft system on control gains and information topology are investigated. Specifically, the control gains which achieve maximal convergence rate are analyzed. Furthermore, two kinds of cell partitions from graph theory are employed to investigate the influence of information topology on steady states of followers, which provides theoretical basis for collision avoidance design. Finally, simulation results show that the designed information topology could meet the requirements of large-scale cluster system, and followers belonging to the same cell have the same steady states. INDEX TERMS Large-scale cluster, orbital control, multiple leaders, containment control, graph theory, topology design.

“…Früh and Jah [13] proposed a semi-coupled approach for propagating the attitude and orbital dynamics of objects near the geostationary ring. Zhao et al [14] investigated the long-term evolution of the smart 3 dust's orbit with the consideration of the gravitational potential. Mengali et al [15] [16] studied the heliocentric dynamics of sun-pointing smart dust which can provide an outward propulsive acceleration directed along the sun-smart dust line.…”

Heliotropic orbits and frozen orbits both possess unique advantages in Earth observation missions and communication service. However, few scholars have found an orbit which possesses heliotropic and frozen characteristics at the same time. This paper obtains novel heliotropic frozen orbits through a proposed control strategy, which is accomplished by adjusting the area-to-mass ratio and the attitude angles. First, we construct the dynamical model of high area-to-mass ratio spacecraft under the effect of J2 perturbation and solar radiation pressure. Then, nominal heliotropic frozen orbits are solved by assuming that the obliquity angle of the ecliptic with respect to the equator is zero. Finally, a control strategy is proposed to maintain heliotropic frozen orbits when the obliquity angle of the ecliptic with respect to the equator is considered. In addition, practical examples are provided to verify the heliotropic and frozen characteristics and the robustness of the controlled orbits. Orbit design for Earth observation and communication service is also studied.
