FIELD: space equipment.
SUBSTANCE: invention relates to space engineering, and more specifically to means of protecting objects in space. Proposed device comprises n contamination sensors, onboard computing machine (OBDC) and standard telemetry system connected to OBDC. In addition, it comprises series-connected first switch, narrow-band amplifier, detector and threshold unit. Besides, there are series-connected first generator, modulator, amplifier-demodulator and second commutator, power supply, third switch and n heaters connected to the third switch. Amplifier-demodulator and narrowband amplifier are provided with amplification control. Power supply is made with control over connection and voltage level. Threshold unit is controlled by threshold. Pollution sensors are made with electrodes which are resistant to sublimation, and with matching circuits.
EFFECT: enabling increase in vital activity of space objects.
