  • Description

    The United States Naval Observatory, the nation's official time-heeper, has a new standard of accuracy for broadcasting time signals which is ten times better than any previously used system of measurements.

    The new standard was made possible by work done with this dual rate moon camera as for back as 1948. Through international cooperation, accuracy has been increased.

    High precision broadcasts of time and frequency will permit more accurate tracking of artificial satellites, improved naval communications and improved radio navigation.

    Control is achieved in the following manner. Time signals are transmitted continuously from radio station NBA in the Canal Zone. The frequency of the carrier wave is compared at Washington with the Naval Observatory's atomic clocks. If upon comparison, Observatory scientists find the frequency varies from atomic time by more than one part in 10 billion, NBA is directed by radio message to correct its transmission frequency.
