An Indian satellite for X-ray and ultraviolet astronomy, launched in 2015 September. It carries an Ultraviolet Imaging Telescope (UVIT) with two 0.38-m mirrors for imaging at far ultraviolet (130–180 nm), near ultraviolet (180–300 nm), and optical wavelengths; three Large-Area Xenon Proportional Counters (LAXPC) for timing and low-resolution spectrometry at X-ray energies 3–80 keV; a coded-mask camera with Cadmium-Zinc-Telluride detector array (CZTI) for higher spectral resolution in the range 10–150 keV; a Soft X-ray Imaging Telescope (SXT) for energies 0.3–8 keV; and a Scanning X-ray Sky Monitor (SSM) for monitoring X-ray transients and other variable sources at 2–10 keV.
