| NAME |
Gamma Ray Burst Detector (OGBD) for Pioneer Venus
|
| TYPE |
Gamma Ray Detector
|
| DESCRIPTION |
The Gamma Ray Burst Detector (OGBD) was an omnidirectional gamma-ray detector designed to observe high-energy gamma-ray bursts from astronomical sources, operating from 1978 to 1992. It utilized two Phoswich scintillation spectrometers sensitive to photon energies ranging from 0.1 to 2.0 MeV, enabling rapid data collection upon detecting gamma events. The instrument featured a full sky field of view and was capable of achieving source location accuracy of under one arc minute by leveraging long-distance data from Earth to Venus. With a total mass of 2.8 kg and power consumption of 1.3 W, the OGBD included multiple energy channels and utilized a pretrigger memory to capture transient data. Its data was compared with other satellite experiments for valid event confirmation.
