Russia is planning to launch four more satellites in its Glonass global positioning system in the last months of this year, RIA Novosti reports from Russia's Aerospace Air Defense Forces on June 8.

The most recent Glonass satellite, Glonass -M, was put on orbit by Russia on April 26, when leaving the Plesetsk launch pad on Soyuz 2-1B rocket.

It is known that the Glonass system was developed by Russia to compete with the US global positioning system GPS, with the first satellite entering orbit since 1993.

Glonass is designed to be used for both military and civilian, with data observing the position and velocity of the object on the Earth's surface, on the sea surface and in the air with a resolution in one meter.

So far, Russia has spent $ 4.4 billion on this program and is expected to spend an additional $ 10 billion in the period 2012-2020.

Currently China and Europe are also developing their own navigation system, named Beidou (Bac Dau) and Galileo respectively.
