Emulation and analysis of spacecraft control domain

Orbit maneuver exhibits significant applications in formation flight, spacecraft information supporting and on-orbit servicing etc. In the paper, we pay more attention to analyze spacecraft´s control domain under extra maneuver ability. According to emulate different direction velocity increment in different plane thrown to spacecraft, we analyze the variation of orbit parameters change with velocity increment. Furthermore, we give some conclusions which can provide theory foundation for the task of spacecraft information supporting and on-orbit servicing.
