Furthermore, a content adaptive IMC algorithm in MCTF, composed of two estimation models, is put forth to reduce the ghosting artifacts. One model is based on characteristic of subbands coefficients for low activity region estimation, and the other is to estimate the MV accuracy in high subbands from the energy after ME. Artifacts, caused by inaccuracy ME or update step, can be reduced effectively by the estimation models.

Firstly, from Gauss' equations and relative motion equations, the relation of control impulse and relative motion was expressed as analysis formulas and simplified based on the near circular condition. By deeply analyzing the mechanism of impulses in each directions (radial, in-track and cross-track directions) effect on relative motion respectively, two maneuvers to establish formation flying are provided: one is to utilize the impulses in radial and cross-track directions, the other is to utilize the impulses in along-track and cross-track directions. Both of the two methods can establish satellite formation flying of any configuration. The method with impulses irradial and cross-track directions needs only 3 impulses, while the method with impulses in along-back and cross-track directions needs 4 impulses. Lastly, by an example of establishing a space-circle formation flying, two maneuvers were compared with each other in the amount of impulses and fuel consuming estimation.
