	The Luch 5A was launched on December 2011 and the Luch-5B on November 2012, having reached the geostationary orbit in December 2012.		The Luch 5A was launched on December 2011 and the Luch-5B on November 2012, having reached the geostationary orbit in December 2012. Luch 5V was launched on April 2014.

	~~The~~ Luch ~~family is expected~~ to be replaced by "~~Enisey~~" in ~~the scope of the SDCM evolution~~<ref name="~~SDCM_ION_2012~~">~~SDCM Program Status, Sergey KARUTIN, Deputy head of division, Russian Space Systems, presented at ION GNSS 2012~~</~~ref~~>.		All current Luch satellites were to be replaced by the Luch 5M variant starting 2021 but their launches have been delayed to 2022 in the first place and again to 2025<ref name="Luch">[https://space.skyrocket.de/doc_sdat/luch-5m.htm Luch M information]</ref>. These satellites will broadcast SBAS data in L1 and L5 signals<ref name="SDCM_2019"/>. The ground stations network is also expected to grow in the next years<ref name="SDCM_2019"/>.

	SDCM system tests have been completed and system certification has been planned for 2020. Initial service will be SBAS L1 over Russian territory. L1/L5 SBAS and L1/L3 GLONASS precise point positioning service are under planning<ref name="SBAS_2020">[https://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/library/briefings/media/SBAS_Global_Status_Feb_2020.pptx Global SBAS Status (FAA)]</ref>.

	The positioning performance provided by SDCM will be of 1 to 1.5 meters in the horizontal plane and of 2 to 3 meters in vertical. In addition, it is expected to offer a cm-level positioning service for users at a range of 200 kilometers of the reference stations.<ref name="SDCM_INGNSS">Glen Gibbons, [http://www.insidegnss.com''Russia Building Out GLONASS Monitoring Network, Augmentation System''] Inside GNSS News, September/October 2009</ref>		The positioning performance provided by SDCM will be of 1 to 1.5 meters in the horizontal plane and of 2 to 3 meters in vertical.

	In 2014, the observed accuracy of the system oscillated between 0.44 m and 2.19 m in the plane and from 0.23 m to 4.77 m in the vertical along most of the Russian territory. Plans beyond 2020 consider a 0.5m accuracy<ref name="SDCM_2019">.
