摘要:
我们提出了一种简单方法用于估算惯性辅助全球导航卫星系统(GNSS)接收机中晶体振荡器的g灵敏度。该方法不需要任何特定设备,如GNSS信号模拟器或速率表。该方法基于分析闭环相位跟踪误差。这使我们能够利用实际的GNSS信号作为频率参考,尽管其中存在未知的多普勒频移。该方法已成功应用于振荡器的校准。
英文摘要:
We propose a simple method for estimating crystal oscillator g-sensitivity in inertially aided Global Navigation Satellite System (GNSS) receivers. It does not require any specific equipment, like GNSS signal simulators or rate tables. The method is based on analyzing closed-loop phase tracking errors. This enables us to utilize the actual GNSS signal as the frequency reference, despite the presence of an unknown Doppler shift in it. The method has been successfully applied to the calibration of an oven-controlled crystal oscillator.
