METHOD OF ELECTRIC CHECKS FOR SPACECRAFTS Russian patent published in 2014 - IPC B64G5/00 

FIELD: electricity.

SUBSTANCE: invention refers to land checks of spacecrafts and preparation for routine operation. Method involves spacecraft (SC) switching on and off, including electric power sources, particularly accumulator batteries (AB). Before SC actuation, stabilised land power sources are connected to AB, and after SC deactivation, current of AB boost charge from those sources is monitored additionally. That current is indicative of routine completion of SC deactivation process. In addition, boost charge current is used to assess AB loss current with SC switched off, that should not exceed a set value.

EFFECT: improved reliability and expanded functionality for the process of SC electrical checks.
