An attitude control logic for a pitch bias momentum geostationary satellite with a skewed roll/yaw magnetic torquer in an inclined orbit is presented. The inclined orbit operation for geostationary satellites is primarily targeted to saving onboard f

A new output-feedback control approach for the single-axis rotational maneuver of a e exible structure by use of on‐off thrusters is discussed. The target structural model represents a large-space-structure type with relatively lownaturalfrequencie

A new feedback control law design for the dual-spin turn maneuver of spinning spacecraft is discussed. The control law design study is motivated by stability analysis of dual-spin spacecraft. The feedback control law is based on the relationship betw

Koreasat 1 consumed much of its on-board fuel during orbit acquisition. Therefore, its lifetime was reduced to 4.4 years. The inclined orbit operation scheme is being established to extend its lifetime. In this paper, an inclined orbit operation sche
