Development of GPS-systems of ultra-small space vehicles attitude control.

A new principle of attitude control system of ultra-small spacecraft (SKA) is developed, which is based on the determination of the spatial orientation of SKA by information of multi-antenna GPS-system and further usage of this information in the control loop of engine-flywheel (EF) - executing element of control system of angular motion of SKA. Methods and algorithms for determining the spatial orientation of SKA are investigated, as well as methods and algorithms for signal generation of the angular acceleration, which will significantly expand the resources of the precision of EF.
