%0 Journal Article %T Partially Invariant System for Spacecraft Center of Mass Motion Stabilization %A Nickolay Zosimovych %J Scientific & Academic Publishing %D 2019 %R 10.5923/j.aerospace.20190701.02 %X This publication suggests how we can improve the spacecraft centre of mass movement stabilization accuracy in the active phases of trajectory correction. It will be during interplanetary and transfer flights, which in some cases provides for high navigation accuracy, when rigid trajectory control method is used. The required stability conditions obtained are consistent with the known criteria in the invariant theory. Computer modelling shows that in a partially invariant stabilization system reveals the significant advantages of such a system in terms of greater accuracy when compared to known stabilization systems %K Operating device (OD) %K Feedback (FB) %K Control actuator (CA) %K Control system (CS) %K Angular stabilization (AS) %K Centre of mass (CM) %U http://article.sapub.org/10.5923.j.aerospace.20190701.02.html
