Study results of develo** formation control system for multi-spacecraft that requires
avoiding obstacles and maintaining the formation configuration are presented. In particular …

Study results of develo** control system for spacecraft formation proximity operations
between a target and a chaser are presented. In particular, a coupled model using dual …

This study proposes a rapid algorithm to achieve relative orbit transfer based on constant-
vector thrust acceleration control, where the magnitude and direction of the thrust …

Abstract Space object observation requirements and the avoidance of specific attitudes
produce pointing constraints that increase the complexity of the attitude maneuver path …

Lambert's problem involves solving the orbits connecting two position vectors with a given
flight time. When introducing variations to the input of this problem (that is, terminal positions …

The fundamental solutions of the Tschauner–Hempel equations, which describe the motion
of a deputy satellite relative to a chief satellite with arbitrary eccentricity, are interpreted …

Relative motion of one satellite about another in circular orbit, where the two objects have
the same semimajor axis, is periodic in the linearized approximation. A set of orbital …

A novel approach based on Lagrange's time equation and differential orbital elements is
developed to solve the relative Lambert's problem for circular reference orbits. Compared …

The Newton–Kantorovich/Chebyshev pseudospectral method is systematically investigated
to solve perturbed astrodynamic two-point boundary-value problems. Because many …

To support China's lunar exploration mission requirements of high-latitude landing and
anytime return, ie, the capability of safely returning the crew exploration vehicle at any time …
