GPS时间比对数据的Vondrak平滑和三次样条插值处理

Processing for GPS Time Comparative Data with Vondrak Smoothing and Cubic Spline Interpolation

介绍了Vondrak平滑方法和三次样条插值方法。利用国家授时中心时间频率基准重点实验室的GPS时间比对数据,先进行预处理和规范化处理,再采用Vondrak平滑方法和三次样条插值方法进行处理,得到的结果表明:在实际中利用Vondrak平滑方法和三次样条插值方法对GPS时间比对数据处理是可行的,减弱了随机噪声的影响。

It expatiates the method of vondrak smoothing and cubic spline interpolation. It uses the method of Vondrak smoothing and cubic spline interpolation to processes GPS time comparative data which is pre-processed and standardized belonging to Time ＆ Frequency Standard Key LAB of NTSC. The result shows that processes for GPS time comparative data with Vondrak smoothing and cubic spline interpolation is feasible and reliable. So random noise is weakening.
