Abstract:

The main goal of RELEC mission is the study of relativistic electron precipitations from magnetosphere and their impact onto upper atmospheric layers, as well, as transient luminous events (TLE) observation in a wide range of electromagnetic spectrum. RELEC set of instruments will be presented and their performance will be discussed. RELEC mission science includes: - simultaneous observations of energetic electron & proton fluxes (energy range ~0.1-10.0 MeV and low-frequency (~0.1-10 kHz) electromagnetic wave field intensity variations with high temporal resolution (~1 ms); - fine time structure (~10 microseconds) measurements of transient atmospheric events in UV, X- and gamma rays with a possibility of optical imaging with resolution of a few km in a wide FOV; - measurements of electron flux pitch-angle distribution in dynamical range from ~0.1 up to 105 counts/cm2s; - monitoring of charge and neutral background particles in different areas of the near-Earth space. After RELEC successful launchon July, 8 2014 to the solar-synchronous orbit, with apogee 820 km and perigee 620 km, all instruments were switched-on and more than 1 Gbyte data were collected.
