● Explosion warning telescope (BAT), which uses an imaging plate with a coding hole, has an area of 5200 square centimeters and an operating energy range of 15-150 keV.

● X-ray telescope (XRT), which can Gamma ray bursts The position of the gamma ray burst is accurately measured with an error of about 3.5 angular seconds and an operating energy range of 0.2-10keV. At the same time, it can also monitor the light change curve of afterglow in days to weeks.

● Ultraviolet/ Optical telescope (UVOT), operating at 170-650 nm, can Gamma ray bursts Imaging in the afterglow of the optical band can also measure its brightness, spectrum, and long-term light curve.
