NORAD Catalog Number is also known as U.S. Space Command (USSPACECOM) object number and NASA catalog number. 2. The numbers listed first in the "Kosmos Numbers" column are the designators assigned by the Russian Federation. Formerly, NORAD had sometimes assigned different designators due to confusion in first tracking tripple-launched satellites. Recently, NORAD switched the designators of GLONASS satellites to the Russian ones back to Kosmos 2206 and perhaps to even earlier launched satellites. Recently, the GLONASS Control Center has switched the Kosmos numbers of GLONASS 796 and 712 to 2411 and 2413 respectively in its GLONASS status reports. It is not known if this is a real change or just a typographical error. 3. Channel number, k, indicates L1 and L2 carrier frequencies: L1 = 1602. + 0.5625 k (MHz) k L2 = 1246. + 0.4375 k (MHz) k 4. Status codes: Res = satellite not in service but held in reserve. OK = satellite fully operational. UNH = satellite currently flagged unhealthy. CHK = satellite undergoing checkout and commissioning. The date listed is the date the satellite was removed from service (Moscow Time) as reported by the Coordinational Scientific Information Center, Moscow. 5. All GLONASS satellites employ cesium atomic clocks. 6. The first GLONASS satellite was launched on 12-Oct-82. GLONASS 1 through 82 are no longer in service. 7. GLONASS 40 and 41 were launched with the Etalon 1 laser ranging satellite. GLONASS 42 and 43 were launched with Etalon 2. 8. The GLONASS numbering scheme used in this table includes the 8 "dummy" satellites orbited as ballast along with "real" satellites on the first 7 GLONASS launches. The second number in the "GLONASS Numbers" column is that assigned by the Russian Space Forces. 9. New GLONASS channel allocations were introduced in September 1993 aimed at reducing interference to radio astronomy. Note the use of the same channel on pairs of antipodal satellites. 10. The most recent triple GLONASS launch took place on 25-Dec-06 at 20:18 UTC. GLONASS 715 and 717 became usable on 3-Apr-07 at 03:30 UTC (ref. NAGU 043-070404 and 044-070404). GLONASS 716, transmitting on frequency channel 0, is not yet operational. 11. GLONASS 701, 712, 713, 714, 715, 716, and 717 are GLONASS-M satellites. 12. GLONASS 711 is a development or prototype GLONASS-M satellite. It has been set unhealthy since 9-Jul-06 (ref. RSA). 13. The frequency channel for GLONASS 712 was switched from 4 to 5 on 12-Feb-07 (ref. Czech Technical University). 14. GLONASS 783 has been set unhealthy since 25-May-07 at 02:44 UTC (ref. NAGU 066-0705250. 15. GLONASS 787 had been set unhealthy since 12-Sep-06 at 16:39 UTC (ref. NAGU 147-060913) and was withdrawn from service on 16-Apr-07 (ref. NAGU 052-070425). 16. GLONASS 791 has been set unhealthy since 5-Feb-07 at 21:11 UTC (ref. NAGU 023-070206). 17. GLONASS 793 had been set unhealthy since 21-Sep-06 at 21:45 UTC (ref. NAGU 148-060922) and was withdrawn from service on 16-Apr-07 (ref. NAGU 053-070425). 18. GLONASS 794 has been set unhealthy since 19-Apr-07 at 21:38 UTC (ref. NAGU 048-070420). 19. Some GLONASS satellites are temporarily unusable at times due to power problems while the satellites are in their eclipse seasons. 20. Number of GLONASS satellites currently in service: 16. 21. Number of GLONASS satellites currently usable: 12. 22. Constellation plot: . 23. Next GLONASS launch is expected in September 2007. 24. Status of satellites compiled by Richard B.
