| Abstract: | 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. |
