Operation hamster
The operation hamster (also measure hamster or action hamster ) was the search for a buried automatic radiosonde in the German democratic republic (GDR). She collected microseismic data from ground vibrations from motor vehicle traffic to and from the Schneeberg ammunition depot of the National People's Army in the area of the city of Beeskow . The data sent the radiosonde every Sunday in a 300 millisecond burst of data on the frequency 306.450 MHz to a US - communications satellites .
The transmitter signal from the probe was first recognized by the GDR authorities on November 6, 1988. After four months of technical investigation by MfS main department III ( radio reconnaissance and radio defense), the radio probe was clearly located on February 26, 1989. After its behavior was further observed, the probe was recovered on October 22, 1989. After further detailed investigation, it was presented to the public on November 24, 1989 at a press conference by the Stasi successor, the Office for National Security . An American intelligence service is suspected to be the still unknown originator of the radiosonde .
The radiosonde had a predecessor in the GDR territory, which was found in May 1985 near the Biesenthal ammunition depot . A successor was revealed in January 1990 near Irfersgrün after only five broadcasts.
