GPS 跟踪环路性能分析, TCXO, OCXO, XO,不同机动,动态的比较,对相位噪声的影响, 仿真-GPS tracking loop performance analysis, TCXO, OCXO, XO, different motor, dynamic comparison of the impact of phase noise simulation

对gps的1pps信号进行平滑滤波处理，然后驯服恒温晶振，得到原子钟级稳定度的信号。-1PPS on GPS signals are filtered and then tamed OCXO, get the signal level stability of atomic clock.
