BATSE (Burst and Transient Source Experiment) was an instrument aboard the Compton Gamma Ray Observatory that detected and located gamma-ray bursts in the sky.
BATSE was a high energy astrophysics experiment in orbit around Earth on NASA's Compton Gamma-Ray Observatory. The primary objective of BATSE was to study the phenomenon ofgamma-ray bursts , although the detectors also recorded data from pulsars , terrestrial gamma-ray flashes , soft gamma repeaters, black holes, and other exotic astrophysical objects.
BATSE responded to, or triggered on, sudden changes in count rates above background levels. It was also capable of detecting less impulsive sources by measuring their modulation using theEarth Occultation technique. View a typical one-day orbit of the Compton Gamma-Ray Observatory.

The Compton Gamma Ray Observatory was removed from orbit by NASA on 4 June, 2000 bringing to an end the successful 9-year CGRO mission. During its operation, BATSE recorded 8000 triggered events .
