Magnetometers

Function

  • measurements of quasistatic and alternative magnetic fields at low Earth orbits and in the deep space;
  • monitoring of electromagnetic emissions in the spacecraft environment (electromagnetic cleanness of the spacecraft system and payload);
  • magnetic sounding of celestial bodies.

    Description

    The system consists of: Magnetometry experiments are presently developed and manufactured for the Russian Spectr-R, Phobos-Grunt space missions, Chibis microsatellite and experiment Trabant at the ISS.
