Pulsar clock : ウィキペディア英語版 | Pulsar clock
A pulsar clock is a clock which depends on counting radio pulses emitted by pulsars. ==Pulsar clock in Gdańsk== The first pulsar clock in the world was installed in St Catherine's Church, Gdańsk, Poland, in 2011. It was the first clock to count the time using a signal source outside the Earth. The pulsar clock consists of a radiotelescope with 16 antennas, which receive signals from six designated pulsars. Digital processing of the pulsar signals is done by an FPGA device.
