He added that an exception would be made for top-secret facilities.

Defense Minister Sergei Ivanov in February ordered that restrictions be lifted on civilian use of the systems this year, saying the move "would yield a considerable economic and anti-corruption effect."

Experts say that in 10-15 years cellular phones, watches and car stereos will have receivers for satellite signals.

The Glonass system currently has 17 satellites and two laser reflectors in orbit.

The first launch under the project took place on October 12, 1982, but the system only officially came online on September 24, 1993.

The satellites currently in use are of two modifications: Glonass and the updated Glonass-M. Glonass-M satellites have a longer service life of seven years and are equipped with updated antenna feeder systems and an additional navigation frequency for civilian users.

A future modification, Glonass-K, is an entirely new model based on a non-pressurized platform, standardized to the specifications of the previous platform, the Express-1000.

The Glonass-K is a small spacecraft that is considerably lighter than previous models, making it less expensive to put into orbit. Improved weight specifications also mean that more carrier rockets can carry it. The craft's estimated service life has been extended to 10-12 years and a third "civilian" L-range frequency added.
