English: Gamma-ray burst detectors have been carried by elements of the Franco- Soviet SIGNE program. SIGNE 1 was a package of experiments flown on the Prognoz 2 satellite; SIGNE 2 was aboard the Prognoz 6. SIGNE 3 was a small French-built satellite (also known as Gamma D2B and Sneg-3) which was originally intended to be launched by the French Diamant rocket, but was actually launched by the Soviets when the Diamant program terminated. Other SIGNE packages were carried aboard Prognoz 7, Prognoz 9, Venera 11, and Venera 12.
There were 2 instruments onboard: a gamma-ray telescope and a solar UV experiment. The gamma-ray spectrometer installed on the French SIGNE-3 satellite had 14 differential channels in the 20 keV to 10 MeV range and 256 channels for amplitude analysis in the 200 keV to 2.5 MeV range.
