1. 1 SDCM development program status 25 th meeting of Interoperability Working Group Sokos hotel Olympia Garden, St. Petersburg, Russia June 25, 2013 25 th meeting of Interoperability Working Group Sokos hotel Olympia Garden, St. Petersburg, Russia June 25, 2013

2. 2 Content SDCM status –System architecture –Flight tests SDCM development program –Preliminary design review results –Constellation perspectives

3. 3 SDCM components Processing Facilities Main (Moscow, RSS) RIMS network 19 stations in Russia 4 stations abroad Broadcasting channels 2 L1 GEO SiSnet server

4. 4 SDCM service performance June 17, 2013

5. 5 SDCM first flight test Myachkovo aiport Moscow region May 15, 2013

6. 6 SDCM development goals L1 SBAS coverage over Russian territory by 2016 L1/L5 SBAS service and L1/L3 GLONASS precise point positioning service in 2018 SDCM certification for APV-2

7. 7 Future SDCM network 53 RIMS: 46 RIMS in Russia 7 RIMS along the border

8. 8 Constellation development Luch -5A ground uplink station deployment Luch-5V transponder and uplink station upgrade to avoid NSS-6 conflict Luch-5B Luch-5A Luch-5V

9. 9 SDCM development schedule Years First phase L1 full coverage Second phase Certification SV1, Luch-5A, 167 E SV2, Luch-5B, 16 W SV3, Luch-5V, 95 E SV4, Enisey-A1, 95 E SV5, TBD SV6, TBD Constellation Phases Operational Development Service Tests

10. 10 Conclusion SDCM development program is clearly defined. Dynamic PRN mask will be implemented during the second phase There is a possibility to use GLONASS CDMA signals to improve SBAS service for different users SDCM development is impossible without international cooperation
