METHOD OF ELECTRIC INSPECTIONS OF SPACECRAFT Russian patent published in 2015 - IPC B64G5/00 B64G7/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to ground tests, also in manufacturing of spacecrafts (SC). SC comprises a power supply system with on-board sources: solar (SB) and accumulator (AB) batteries, and also a stabilised voltage converter (SVC) with charging and discharging converters. SVC serves to match operation of SB and AB and supply with stabilised voltage to modules of service systems and payload. The method provides for connection and disconnection of the SC (including ground simulators of AB and SB), automated generation of control commands, pre-start control of discrete and analogue parameters from a telemetering system, parameters of an on-board computing system, etc. In process of SC inspections they additionally monitor analogue parameters of ground simulators of AB and SB and in combination with discrete and analogue parameters from the telemetering system they form secondary parameters for their subsequent pre-start control. As the latter they use values of auxiliary supply of SVC, charging and discharging converters, as well as voltage drop in circuits of ground simulators of AB and SB calculated according to certain formulas. Secondary parameters serve for additional assessment of SC operability.

EFFECT: increased reliability of SC electric inspections.
