Frequency Stability Analysis and Noise Identification of BD Satellite Clock
Luo Fa · 2014
The theory of frequency stability analysis and noise identification is introduced. The overlapping Hadamard variance is used to evaluate the frequency stability of four BD satellite clocks. The main noises which affect the performance of satellite clocks are analyzed with Lag1 autocorrelation function. The results show that the frequency stability of the satellite clocks is about the level of 10-13/ d, and the main noises are White FM, Flicker FM and Random Walk FM.
