GPS disciplined oscillator (GPSDO), is a combination of a GPS receiver and a high-quality, stable oscillator such as a quartz or rubidium oscillator whose output is controlled to agree with the signals broadcast by GPS and GNSS satellites. GPSDOs work well as a source of timing because the satellite signals must be accurate in order to provide positional accuracy for GPS in navigation. These signals are accurate to nanoseconds and provide a good reference for timing applications. GPSDOs are used as the basis for Coordinated Universal Time (UTC) around the world.
