Plasma-wave complex (PWC)

Function

Plasma- wave complex PWC measures electromagnetic fields and plasma waves of natural and technogenic origin in the ionospheric plasma and electromagnetic parameters of space weather.

Description and main characteristics

The PWC in the version Obstanovka-1 (Environment 1st stage) onboard the International Space Station includes following elements:

• two flux-gate magnetometers DFM1 and DFM2 (range— ±64000 nT, sensitivity — 1 nT);
• combined wave sensors CWS-1, CWS-2 for measurements of alternating magnetic and electric fields and current fluctuations (frequency range — 0.1–40 kHz);
• spacecraft potential sensors DP-1, DP-2, (0–200 V);
• cylindrical Langmuir probes LP-1, LP-2, (electron temperature — 1000–6000 K, electron density —10⁹–10¹³ m^–3);
• correlating electron spectrograph CORES (0.01–10 keV);
• radio frequency analyzer RFA (frequency range — up to 15 MHz);
• analyzer of low frequency emissions SAS3 (0.1–40 kHz);
• data acquisition and control units DACU1, DACU2 and the information storage unit ISU.
• thermal control systems ASOTR1 and ASOTR2;

The total mass is 55 kg. The power consumption is 60 W. Currently flight models are in production.
