Abstract :
It is shown that onboard values of the frequency stability oscillators in the GLONASS mid-orbital navigation system are at the prescribed level, which does not exceed 3 × 10-13, and meet system requirements. Practical agreement between onboard stabilities and those in ground tests indicates the good reproducibility of the oscillators´ performances as well as their fair immunity to destabilizing factors onboard
