摘要 | In order to realize satellite sweep imaging and reduce the influence on satellite attitude during the process of load swing, a method of two same loads swing symmetrically was put forward. And the swing principle with angle in the given range was planned. Each load had angular velocities of 0.6()/s, 6()/s in roll and pitch axis. Through the dynamics and kinematics analysis of two loads swing motion, the proposal of satellite yaw axis extra moment compensated by reaction flywheel was raised. Then some satellite was used as an example to carry out simulation and analysis, the results showed that the mixed moment and angular momentum in roll and pitch axis had no impact on satellite attitude in the process of two loads swing symmetrically, respectively, an extra periodic moment existed in the yaw axis. 0.2 Nm reaction flywheel was used to compensate momentum, and the satellite attitude pointing accuracy and attitude stability achieved were within 0.032and 0.006()/s, which could guarantee higher accuracy on the surface area of sweep imaging. It was concluded that two symmetrical load body schemes could satisfy the demand of satellite sweep imaging and the design concept was feasible. , 2015, Chinese Society of Astronautics.
