Ginga integrated onto the rocketIntegration of the Ginga satellite into its launch rocket
Ginga carried three different instruments that allowed it to see the sky in X-rays ranging from 1 to 500 keV. The Large Area Proportional Counter (LAC) and the All-Sky Monitor (ASM) were both proportional counter detectors, with the LAC being the largest X-ray detector flown in space up to the time of Ginga.
Large Area Proportional Counter (LAC): the main science instrument on Ginga, it is made up of 8 proportional counter units that can detect X-rays from 1.5 to 37 keV.
All-Sky Monitor (ASM): two proportional counter units that observe a large portion of the sky for X-rays in the range of 1 to 20 keV.
Gamma-ray Burst Detector (GBD): two detectors, one proportional counter and one solid state detector, to detect and record the spectra of gamma-ray bursts in the energy range of 1.5 to 500 keV.
