Formation Flying Relative Motion Of Autonomous Navigation And Control Research

The technology of Formation Flying is a term of crucial technology for the activity of space development in the future. It is of very important meaning studying autonomous navigation and control for the space activity in our country. From relative motion theory, this paper projected methods of autonomous navigation and control and show the result of calculate. There are 6 chapters in this paper, mean contents as follow:In chapter 1, introduction was showed.In chapter 2, some essential reference frames were set up for study Formation Flying. Transform relation of these reference frames were showed. Models of Formation Flying of orbit and relative motion were showed in this chapter.In chapter 3, factors that affect Formation Flying were showed and J₂ term was discussed especially.In chapter 4, math modal of relative navigation was showed and extended kalman filter (EKF) method was showed. Results of calculate show availability of EKF.In chapter 5, characteristics of relative motion of Formation Flying were showed when there are some control flow. From this characteristic, character parameters were defined. Expression of these parameter were showed based on C-W equation.In chapter 6, tasks of autonomous control of Formation Flying were showed. Motion programming was constituted based on characteristics of relative motion. Repository which includes math models and cybernetics was set up. Results of simulation showed autonomous control can achieve preferable precision and low level of fuel consume.In this paper, forming, keeping, leave and entry of Formation Flying were discussed all things considered and deeply. There are some useful reference value and practice meaning in this paper for farther study of Formation Flying.
