System for Transmitting Reference Frequency and Time Signals to Measurement Resources of the Glonass Ground Complex by Optical Cable

We present a system of transmission of reference frequency and time signals to non-interrogating and interrogating measuring facilities of the ground-based GLONASS complex for control of onboard time scales of the navigation system spacecraft. The proposed transmission system is implemented using fiberopticcommunication lines. We present results of experimental studies of the error in the transmission of reference frequency and time signals using fiber-optic communication lines.
