RUBIDIUM SOURCE WITH OCXO

– TYPICAL PHASE NOISE PERFORMANCE

GNSS/GPS Disciplined Oscillator (GPSDO)

When the stability of an atomic or crystal source is not sufficient a GNSS

disciplined source is an option. A GNSS receiver is installed and timing
information from the GNSS is used to discipline the timing device. Timing
accuracy to a ~E-12 is readily achievable.

The GNSS is used to provide timing for a control loop that modulates the

OCXO to bring it in alignment with the PPS timing information. A GNSS timing
source has considerable short-term instability due to the numerous radio
effects - multi-path, signal weakness, etc. In order to develop a stable
reference, the GNSS timing waveform is used to discipline a low noise source
with a Kalman Filter. A good example of the improved jitter performance of a
Kalman Filter is shown below:
