Test of GLONASS precise-code time transfer

In a first attempt to evaluate performance of the Global Navigation Satellite System (GLONASS) precise-code time transfer, one-site measurements are used to show that single-channel GLONASS P-code, combined with temperature-stabilized antennas, reduces the noise experienced by time-receiving equipment to a few hundred picoseconds over an averaging time of one day, thus allowing frequency comparison at a level of a few parts in 1015.
