Relec is a set of the instruments mounted at the small satellite "Vernov" which was manufactured
by Lavochkin Scientific and Production Association (Khimki, Moscow reg., Russia)
in the interests of Lomonosov Moscow State University
More info.
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.
