改进卡尔曼滤波算法在时钟驯服技术中的应用

Application of Modified Kalman Filter Algorithm in Clock Disciplining Technology

时钟驯服系统中GPS信号存在随机抖动的情况,本文提出了一种改进的Kalman滤波算法,并对算法的原理、实现及实验验证进行了阐述。由实验结果可见,该算法很好的消除了抖动带来的误差,将误差控制在了±2ns之内,具有较好的应用价值。

Aiming at GPS pulse noise in clock disciplining system, a study on modified Kalman filter algorithm is given in this paper. Theory, realization and test of algorithm are surveyed in detail. The rithm can much eliminate the error of pulse noise,which has much application value.
