## A Fiber Optic Line to Transfer and Measure 1pps Delays in the RT-13 VLBI Telescope

Transactions of IAA RAS, вып. 50, 73–78 (2019)

Keywords: VLBI, comparison of time scales, comparison of remote frequencies standards, VLBI system of new generation, optical fiber

### 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.
