Abstract
When calculating a gimbal angle trajectory that satisfies boundary conditions set by an attitude boundary condition setterof the ground station, a gimbal angle trajectory calculatorcalculates the gimbal angle trajectory that minimizes a period of an acceleration interval within a range that satisfies driving restrictions of a gimbal, based on a gimbal angle θof a start time and a gimbal angle θof a fixed interval of an attitude change. Also, the gimbal angle trajectory is calculated that minimizes a period of a deceleration interval within a range that satisfies the driving restrictions of the gimbal, based on the gimbal angle θof the fixed interval and a gimbal angle θof a completion time of the attitude change. The obtained θ, θ, θand an attitude change period τ are transmitted to the artificial satellite as gimbal angle trajectory parameters, and the control moment gyros are controlled based on the gimbal angle trajectory parameters.
