| 摘 要： | 针对GPS锁定晶振频率标准,提出了一种滑动平均值法滤波方法,通过这种算法建立新的取样值与历史取样值相关性,适当选取取样点数形成滑动滤波窗口,改变滑动滤波窗口大小,能有效克服GPS接收机输出的1×10^-6的波动影响,可以在很短的时间间隔内解算出被控晶振与GPS的偏差值。应用于控制算法,不断修正压控晶振的频率,使晶体振荡器锁定在GPS频率标准上。

| Abstract: | a novel shift average numeric filter method aimed at the GPS Disciplined VCXO frequency standard is invented,through this method,the correlation between the lasted sample data and the frontal data. Given a propriety window sample number,it can reduce the influence on GPS receiver 1 ×10^-6 output. It can determined the error between VCXO output and GPS output, continuously adjusting the VCXO＇s frequency,it can be disciplined by the GPS fast. |
