Bleien Radio Observatory, Radio astronomy observatory in Gränichen, Switzerland.
Located 5 kilometers south of Gränichen at 469 meters elevation, the facility contains two parabolic antennas measuring 7 and 5 meters in diameter.
The ETH Zurich established the observatory in 1979 under Professor Arnold Benz's leadership, introducing the first fully digitized remote-controlled receiver system.
The observatory stands as a center for scientific education where students and researchers conduct radio astronomy observations and develop new technologies.
The facility maintains two radio telescopes separated by 100 meters, operating across frequencies from 10 MHz to 5 GHz for astronomical measurements.
Between 2005 and 2015, the observatory possessed the largest bandwidth capacity worldwide for conducting solar radio observations.
