Scientific equipment of the satellite

The RELEC experiment was specially developed for study of relativistic electrons in near-Earth space together with TLEs in order to test possible connection between these two phenomena. RELEC mission includes x-ray and gamma-ray spectrometer, 3-axis detector for electrons, UV and red-light flash detector, fast optical imager, low-frequency and radio-frequency analyzers of electromagnetic field and waves. Data from RELEC mission will be processed for testing TLE models, studying of TGF light curves and spectra, testing possible connection between electron precipitations and low-frequency electromagnetic waves.
