Abstract:	While being high-precision satellite navigation systems, GPS and GLONASS enable at the same time a global high-precision user time synchronization with respect to UTC. The simplest synchronization procedure via GPS/ GLONASS signals that does not need to use additional data is the direct synchronization technique, or travelling satellites. Presented in this paper are the results of estimating user clock synchronization accuracy with GPWGLONASS signals on the basis of RIRT’s operational time/frequency reference standard. Commercial navigation receivers, such as GEM SRS-01 (for GPS signals) and ASN-16 (for GLONASS signals), were used as signal receivers. Mea- surement sessions with GPS and GLONASS were con- ducted at the same time over five days. Session duration was 15 min, with the rate of unit count of 15 s. The investigations conducted have indicated that the user clock synchronization accuracy (r.m.s.) was about 55 ns with 20 ns correspondingly.
