In the coming two or three years all Astrakhan river fleet including crafts, motor boats and small-sized vessels will be equipped with GLONASS navigation systems. These navigation terminals will help to continuously track ships in inland waterways. Virtually all large-sized river vessels have already been connected to GLONASS satellite-based navigation system.
GLONASS navigation system is intended to define location and motion speed of maritime, airborne, ground and other kinds of transport. GLONASS comprises 24 satellites located in 3 orbital planes (8 satellites in each plane).
