| Abstract: |
| Periodical calibration of frequency standard for GNSS receiver is an important m
easure to guarantee the positioning preci
sion.
The working principles and hardware structure of frequency calibration system b
ased on GPS disciplining Rubidium clock are introduced. The frequency calibratio
n experiment validates that this system has achieved the preferable long frequen
cy accuracy and short frequency accuracy, which ensures the calibrated frequency
standard precision. |
| Key words: GNSS receiver frequency calibration GPS disciplined Rubidium clock time difference measurement |
