Circumnavigation control design of space flight vehicle using bearing measurement only

The fly-around guidance control problem for non-cooperative target in orbital space is studied in this paper, in which only the relative angle measurement information and the space flight vehicle own motion information are available. We first established the mathematical model of the fly-around problem to describe the relative motion between a flight vehicle and its target, and the circumnavigation control problem is formulated as a math problem. Then, we design a control law of fly-around process and the convergence of the control law is also proved. Finally, the effectiveness of the proposed circumnavigation control design law is shown by some numerical simulation results.
