METHOD OF SPACESHIP ELECTRICAL CHECKS Russian patent published in 2012 - IPC B64G5/00 G01R31/00 

FIELD: transport.

SUBSTANCE: invention relates to spacecraft power supply electrical tests. Proposed method comprises cutting in and out onboard power supplies or their ground simulators. Automated system outputs instructions of control, admission control of discrete and analog parameters in response to onboard system of telemetering and control of tracked onboard computer parameters. Insulation of onboard buses with respect to earth is also controlled. Automatic program and operator commands are generated in manual mode as well as test reports and display of test current state. In cutting in spaceship, prior to switching on said power supplies or their simulators, resistance between spaceship supply buses is additionally controlled. If said resistance does not correspond to preset value, spaceship cutting-in is inhibited. Resistance measurement is performed observing polarity of supply busses. Only steady-state electrical resistance is estimated in measurements. In spaceship cutting-out, after switching off onboard power supplies or their simulators, resistance between spaceship supply buses is controlled for measured value to be used for comparative control over said electrical resistance.

EFFECT: higher reliability.
