The GPS-controlled frequency standards are especially suited for use in calibration departments, providing continuous traceability with no need for external calibration. The stability/24h is excellent; one part in a trillion.

Long-term frequency stability is provided from the built-in Cesium-controlled standards in the GPS-satellite. Very high short-term stability comes from the built-in oven controlled crystal oscillator found in the GPS-88; or the built-in Rubidium atomic clock installed in GPS-89, as its local oscillator.
