摘要:

定期对GNSS接收机的外部频率源进行校准是保证定位精度的重要措施。介绍了GPS驯服铷钟频率校准系统的工作原理和硬件组成，通过频率校准实验验证了该系统达到了较好的长期频率准确度和短期频率准确度指标要求，保证了被校准频率源的精确度。

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
