Russia plans to launch six GLONASS navigational system satellites in 2015. All satellites will be launched by Proton-M booster.

As Reshetnev information Satellite Systems Vice  General Designer  Yuri Vygonsky reported the first three Glonass-M satellites are planned to be launched from Baikonur spaceport in Aril-May next year.

In case of success three more space devices will be launched late 2015. Currently 5 of the satellites are ready for the launch.

Besides Russia is going to launch second new generation navigational satellite Glonass-K from Plesetsk spaceport in November-December this year. The satellite will be orbited by Soyuz-2.1b booster.

At the present time there is only one Glonass-K satellite (launched in February 2011) in GLONASS orbital group passing flight tests. It is distinguished by higher accuracy of navigational data and reliability,  its service life was increased from 7 to 10 years.

GLONASS is a Russian analog of American GPS navigational system. According to Roscosmos the accuracy of this system will amount less than 1 meter (at the territopry of Russian Federation). So GLONASS will be comparable to GPS.
