Notes
-----
1.  NORAD Catalog Number is also known as U.S. Space Command (USSPACECOM)
    object number and NASA catalog number.
2.  The numbers listed 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. NORAD switched the designators of GLONASS satellites
    to the Russian ones back to Kosmos 2206 and perhaps to even earlier
    launched satellites.
    In 2006, the GLONASS Control Center switched the Kosmos numbers of 
    GLONASS 796 and 712 to 2411 and 2413 respectively in its GLONASS status 
    reports. It was not known if this was a real change or just a typographical 
    error. However, they have persisted with these changes and so the table
    above has been amended to reflect the changes.
3.  In the "M?" column, modernized GLONASS satellites are indicated with "M."
    "M*" indicates a development or prototype GLONASS-M satellite.
4.  Channel number, k, indicates L1 and L2 carrier frequencies:
       L1   =  1602. + 0.5625 k  (MHz)
         k
       L2   =  1246. + 0.4375 k  (MHz)
         k
5.  Status codes:
    Res = satellite not in service but held in reserve.
    OK  = satellite fully operational.
    UNH = satellite currently flagged unhealthy.
    UNH-DE = satellite flagged unhealthy and being decommissioned.
    CHK = satellite undergoing checkout and commissioning.
    The date listed is the date the satellite was removed from service (Moscow
    Time) as reported by the Information - Analytical Centre, Moscow.
6.  All GLONASS satellites employ cesium atomic clocks.
7.  The first GLONASS satellite was launched on 12-Oct-82.  GLONASS 1 through
    91 are no longer in service.
8.  GLONASS 40 and 41 were launched with the Etalon 1 laser ranging satellite.
    GLONASS 42 and 43 were launched with Etalon 2.
9.  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.
10. 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.
11. The most recent triple GLONASS launch took place on 25-Dec-08 at 10:43:00
    UTC. GLONASS 727, 728, and 729 were set healthy on 17-Jan-09 at 09:30 UTC
    (ref. NAGU 011-090119), 20-Jan-09 at 11:30 UTC (ref. NAGU 015-090121), and
    12-Feb-09 at 07:30 UTC (ref. NAGU 021-090212) respectively.
12. GLONASS 701 has been set unhealthy since 18-Jun-09 at 09:57 UTC (ref. NAGU
    093-090619). Frequency channel switched from 1 to -4 on 14-Sep-09 (no
    NAGU).
13. GLONASS 713 has been set unhealthy since 2-Nov-09 at 13:16 UTC (ref. NAGU
    139-091103).
14. GLONASS 722 had been set unhealthy since 13-May-08 at 21:01 UTC (ref. NAGU
    059-080514). It was set healthy on 6-Aug-08 at 20:56 UTC (ref. NAGU 
    136-080807) however, there appear to be continuing problems with its L2
    signals.
15. GLONASS 726 has been set unhealthy since 31-Aug-09 at 00:31 UTC (ref. NAGU
    107-090901).
16. GLONASS 728 frequency channel switched from 1 to -4 on 14-Sep-09 (ref NAGU
    122-090915).
17. GLONASS 795 had been set unhealthy since 30-Apr-09 at 11:25 UTC and was
    removed from service on 18-Aug-09 (ref. NAGUs 056-090504 and 100-090819).
18. Some GLONASS satellites are temporarily unusable at times due to power
    problems while the satellites are in their eclipse seasons.
19. Number of GLONASS satellites currently in service: 19.
20. Number of GLONASS satellites currently usable: 16.

22. Next GLONASS launches are scheduled for December 2009 and February 2010.
