The Burst and Transient Source Experiment on board CGRO. BATSE made all-sky observations of gamma-ray bursts and flares, as well as observing many other objects between 10 k eV and 5 MeV.

Burst And Transient Source Experiment. One of four experiments aboard the Compton Gamma-Ray Observatory. BATSE observed nearly the entire sky for transient sources, and could position these sources more accurately than earlier experiments.

Acronym for Burst and Transient Source Experiment on board the Compton Gamma-Ray Observatory. The BATSE experiment consists of 8 detectors operating together as an all sky monitor. It has accumulated more GRB data that all previous GRB experiments combined. Interpretation of this data, available starting in 1992, has fueled several different schools of thought on GRBs.
