METHOD OF CONTROL OVER SPACECRAFT THERMAL CONTROL SYSTEM Russian patent published in 2013 - IPC B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to thermal control systems of, mainly, telecommunication satellites. Proposed method comprises telemetry measurements (for example, at poll rate of 0.5 s in preset time interval) of such parameters as thermal control parameters, heat carrier total consumption in liquid circuit and heat carrier temperature at circuit points. Said circuit comprises parallel branches with temperature transducers arranged at their ends. Third temperature transducer is arranged at common outlet. Electrically driven pump forces heat carrier in said circuit. In making, thermal control system is provided with heat insulation at sections between said transducers to define heat carrier volume between said sections and the point whereat two heat carrier flows of said parallel branches get mixed. Measurements data is used to define actual heat carrier flow rate in parallel branches by formulas that allow for transfer delays in measurements by temperature transducers.

EFFECT: higher accuracy, validity of diagnostics and forecast of efficiency.
