GLONASS Time Server
GLONASS is similar to the US-American NAVSTAR-GPS. The satellites of the GLONASS SYSTEM are called URACAN (Hurricane). The satellites orbit the earth on three orbital planes with an inclination of 64.8° towards the equator (GPS 55°). This fact enables the satellites to reach higher over the horizon, which is important for users in higher geographical latitudes, especially in the polar region, like this a more precise height determination can be obtained over the geoid.Just like GPS, GLONASS needs at least 24 satellites to operate properly and to make sure that a minimum of 3 satellites are visible in any location.

Advantages of GLONASS synchronized time servers:
- Worldwide satellite based synchronization
- High accuracy of up to +/-20ns
- Relatively fail-safe by 24 GLONASS satellites
Disadvantages of GLONASS time servers:
- Always unobstructed "view" to the sky of the antenna
- Cable length for L1 GNSS antenna with low loss is only about 70 m
- Dependency of an operator (Russia Federation)
