Formation flight is the key technology for deep space and orbital applications that involve multiple spacecraft operations. For the formation flying missions, orbit design, relative satellite-to-satellite navigation and formation control are the important technologies. Especially, the formation control is the important technology for the formation flight, because many formation flying missions require particular formations for the observation. After launch, the formation deployment should be performed and the formation changing and keeping are indispensable. The desired trajectory for the formation changing should be optimized in term of total fuel consumption or the fuel expense variation. In this study, the guidance algorithms for the spacecraft around the earth with the linearized equation of motion are shown. The algorithms generate the two-impulse trajectory and the trajectory for the spacecraft with continuous low thrust engine. In addition, this paper presents the collision avoidance strategies for formation flight. The method of searching the trajectory under the restriction conditions of the distance between satellites is show.
