Comparison of GLONASS and GPS Time Transfers Between Two West European Time Laboratories and VNIIFTRI

Abstract

The University of Leeds built a GPS/GLONASS receiver about five years ago and since then has provided continuous information about GLONRSS time and its comparison with GPS time. For the last two years VNIIFTRI and some other Soviet time laboratories have used Soviet-built GLONASS navigation receivers for time comparisons. Since June 1991, VNIIFTRI has been operating a GPS time receiver on loan from the BIPM. This offered, for the first time, an opportunity for direct comparison of time transfers using GPS and GLONASS. This experiment shows that even with relatively imprecise data recording and processing, in terms of time metrology, GLONASS can provide continental time transfer at a level of several tens of nanoseconds.
