Instrument details
Acronym KONUS
Full name Gamma Ray Burst Investigation
Purpose To study gamma-ray burst and solar flares
Short description Assemblage of units for: monitoring of gamma-ray burst energy spectra over the energy range 10 keV to 10 MeV; measurement of burst time histories in three energy ranges covering 10 to 770 keV; high-time-resolution measurement (2 ms resolution) for the high-intensity sections of a burst time history; and continuous measurement of the gamma ray and cosmic ray background, interrupted only to read out bursts
Background Cooperation NASA-Roscosmos. Part of a package of instruments to observe the solar wind
Scanning Technique Interplanetary space observation from the L1 Lagrange libration point
Resolution N/A (integrated over the full interplanetary space)
Coverage / Cycle Interplanetary space at 0.064 s intervals
Mass Power Data Rate
