New PRN29/SVN57, launched on day 354, is active as of day 360 (26 Dec
2007). This PRN was declared operational on day 002 (02 Jan 2008).

This PRN is already included in the analysis scheme at CODE. Starting
with our day 360 24UT ultra-rapid and day 360 rapid orbit submission,
the CODE GNSS orbit products include 45 satellites (32 GPS plus 13
GLONASS). 3 of these satellites are currently marked unhealthy/
unusable: G07 (decommissioned from operational service on day 354, but
still active for testing), G32 (reactivated), R23. Currently inactive
are: R02, R03, R05, R21, R22. None of the 3 GLONASS-M satellites
launched on day 359 (25 Dec 2007) are active yet.
