Abstract:	The main phase of GLONASS system developmenthas been coming to the end in 2011. At the moment there are twenty seven navigation satellites, including twenty three regular, three reserve Glonass-M satellites and one Glonass-K. Launches of five Glonass-M and one “Glonass-K” are planned to carry out by the end of this year. It will allow to create the conditions for continuous global navigation service to GLONASS users. Development of GLONASS space complex will be continued by creation of the following generation satellite - "Glonass–K2" which will transmit additional CDMA navigation signals in L1 and L2,L3 bands. In the second half of 2011 year the launch of GEO satellite "Luch–5A" is planned with the system of differential correction and monitoring (SDCM) transponder on-board. SDCM is the first SBAS system which transmits the corrections to ephemeris and clocks for GLONASS and GPS satellites. These facts create a strong basis for the further GLONASS development. Main directions of this development are the implementation of new CDMA navigation signals and improving precise positioning technology on GLONASS and SDCM basis."
