Single Gimbal Control Moment Gyroscopes (SGCMG) can could provide large control torque and quick attitude maneuver rate to small satellites without any increase in power  volume and mass  which will help small satellites become more powerful. Singularity avoidance and failure steering are two important problems to SGCMGs and also the main focus in this field. A new united steering law for SGCMGs with capabilities of singularity avoidance and quick transition of singularity surfaces is developed in this paper. To ensuring the existence of null motion  the commanded output of controller was changed real-timely as the variation of singularity measurement of SGCMGs  which can avoid the gimbal angle rate saturation. This developed steering law could help the SGCMGs provide real-time control toques in spite of limitation of gimbal angle rate. Simulation analysis is conducted for a certain 4-SGCMG system mounted on a small satellite. Simulation results indicate that the steering law is very effective in singularity avoidance. 2010 IEEE.

The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4  (2) Functions such as changing the field-of-view  and the corresponding field of view is 3-12. The working waveband is from 7.5m to 10.5m  focusing for objects at finite distances and athermalizing the system can be achieved by axially moving a single element in the system.  and its total length is required to be no more than 350mm. The final optical system consists of 7 elements  with aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the far infrared waveband. Two conclusions can be drawn from the design. (1) Using diffractive optical elements in the design of an infrared optical system is an effective approach to control color aberrations  which eliminates the need to use exotic and expensive materials and helps to reduce the cost of the system
