... INTRODUCTION Telescopes and spectrometers are designed for mounting on the orbital scientific station of the Mir type with the following characteristics (Orbital Station Mir 1988~: inclination 51.6°; Bight altitude 3~0 km; orbit period 90 min. The total mass determined by the Georgian Academy of Sciences Is 10,000 kg; telemetric information l.m bit/e; energy consumption 700 W

... 1b measure energy spectra, proportional counters are used for detecting X-rays in the energy range 2-30 keV with the sensitive surface 1.2 x 103 cm2, combined station detectors NaVCsI with the diameter of 200 mm are for detection of gamma radiation in the range 15 keV - 10 MeV, and then sensitive surface is 1.2 x 103 cm2. Bursts 1.5 · 10-6 erg/ s are registered by a scintillation detector with the diameter 60 mm and with a semiconductor detector of mercury diodide with a sensitive surface of 1 cm2.

... Measurements of energy and temporal spectra in the energy range 15 to 200 keV and the time resolution 0.1 msec is earned out using the combined NaVCsI detectors with an active and passive collimator, with the angular resolution 2 x 2°, and with the sensitive surface 2 x 104 cm2. Telescope-spectrometers are mounted on an independent platform providing orientation not less than 1 min.
