Characterizing Periodic Variations of Atomic Frequency Standards via Their Frequency Stability Estimates

Characterizing Periodic Variations of Atomic Frequency Standards via Their Frequency Stability Estimates

The onboard atomic frequency standard (AFS) is a crucial element of Global Navigation Satellite System (GNSS) satellites. However, it is widely accepted that periodic variations can influence the onboard AFS. The presence of non-stationary random processes in AFS signals can lead to inaccurate separ...
