Dominion Radio Astrophysical Observatory

The Dominion Radio Astrophysical Observatory (DRAO) is an internationally known facility for science and technology research and development related to radio astronomy. Home to NRC astronomers, astrophysicists, engineers and technologists, as well as visiting researchers and students from universities and astronomical observatories around the world, these facilities support the design and development of leading-edge instrumentation for new and existing telescopes. Operating several telescopes on its extensive radio-quiet site near Penticton BC, DRAO also features laboratories and specialized equipment for design and construction of all aspects of radio-frequency instrumentation, from highly sensitive antennas and receiver systems to high speed digital signal processing hardware and software.
