METHOD OF SPACECRAFT MANUFACTURE Russian patent published in 2013 - IPC B64G1/42 B64G7/00 

FIELD: transport.

SUBSTANCE: invention relates to assembly and testing spaceship onboard systems, primarily, telecommunication spaceship power supplies. Proposed power supply comprises solar and storage batteries and stabilised voltage converter (SVC) for matching said batteries and stable supply of service components and useful load. Apart from assembly, proposed method comprises preparing power supplied for operation and testing the spaceship. Note here that cutoff SVC power circuits are short-circuited on solar cells side by low-power relay switchboards. Solar cells power circuits are connected to SVC after short-circuiting via appropriate low-power temporary circuits. After electric connection of solar cells to SVC bridging circuits are withdrawn. Electronic power switchboards are arranged at SVC input power circuits on storage battery connection side. After pre-charging by limited current of said circuits and charging storage cells the latter are connected to SVC. Circuits are charged to voltage equal to that of open circuit of appropriate storage battery. After connecting storage batteries to SVC, they are periodically charged by ground sources for compensation of leak currents at SVC switched-on state. Pre-charging on storage battery side is performed from appropriate storage batteries via current-limiting resistors of preset resistance.

EFFECT: higher reliability of manufacture.
