Abstract:	GLONASS orbit constellation renewal is at a final stage, 24 navigation satellites will be operational by the end of 2010. These satellites will provide continuous global service with two civil navigation signal in L1 and L2 bands. Russian system for differential correction and monitoring (SDCM) space segment deployment will start in 2011. It has a special payload installed on “Luch” satellites on geostationary orbit (GEO). However GLONASS developing is not limited on deployment of navigation satellites and SDCM. The most important task is a development of future GLONASS design, which could ensure that GNSS users requirements will be fulfilled in a long term perspective. First step in GLONASS evolutional development is a new satellite “Glonass-K” with civil CDMA signal in L3 band. Flight tests of this satellite will start next year. Second possible direction is GLONASS augmentations (including SDCM) development. Augmentations could be used for creation of regional precise service system on satellites, located on geostationary (GEO), geosynchronous (circular (GSO) and elliptical (GISO)), and highly elliptical (HEO) orbits. Different aspects of GLONASS CDMA civil signals evolution and GLONASS precise positioning services development are discussed in this paper.
