Globally-stable Lyapunov guidance and control laws are developed for various maneuvers regarding the tracking and convergence of a chaser spacecraft onto a target, which may in general be tumbling and orbiting the Earth elliptically. Maneuvers such as circular-shaped formation flying, obstacle avoidance, and docking are first developed. A modified, time-varying guidance law using a proportional-controller is then developed, capable of performing such maneuvers while holding commanded thrusts under user-defined thresholds. Applications/limitations of this new guidance law are discussed. Numerical simulation results are presented.
