Radio telescopes, and in particular planet-wide simultaneous joint observations, require extremely precise atomic clocks to provide time and frequency reference. In Metsähovi, there are currently three active hydrogen maser -type atomic clocks.
Metsähovi Radio Observatory facilities are being used for experiments almost 100% of the time. To discuss the possiblity of specific experiments, please contact metsahovi at aalto dot fi.
Clocks (1 pcs)
An atomic clock is a clock device that uses a hyperfine transition frequency in the microwave, or electron transition frequency in the optical or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS.
