Abstract

We have proposed an optical and electronic time transfer method for the RT-13 VLBI telescope of the new generation. The main feature of this method is that it uses a fiber optic line to transfer 1pps signal and to measure 1pps signal delays from the ground part of the telescope to its antenna simultaneously. The scientific novelty of the proposed method is that the accuracy of the active measurement of the signal pulse delays is only a few dosens of picoseconds, which has never been achieved before inside the VLBI telescopes. The method is realised with a single bi-directional fiber optic line connecting the ground part of the radio telescope and its antenna. The line uses the signals multiplexed with the wavelength division of channels.

AB  - We have proposed an optical and electronic time transfer method for
the RT-13 VLBI telescope of the new generation. The main feature of
this method is that it uses a fiber optic line to transfer 1pps
signal and to measure 1pps signal delays from the ground part of the
telescope to its antenna simultaneously.  The scientific novelty of
the proposed method is that the accuracy of the active measurement of
the signal pulse delays is only a few dosens of picoseconds, which
has never been achieved before inside the VLBI telescopes. The method
is realised with a single bi-directional fiber optic line connecting
the ground part of the radio telescope and its antenna. The line uses
the signals multiplexed with the wavelength division of channels.
