This PRN is already included in the analysis scheme at CODE. Starting
with our day 298 12UT ultra-rapid and day 298 rapid orbit submission,
the CODE GNSS orbit products include 42 satellites (31 GPS plus 11
GLONASS). 3 of these satellites are currently marked unhealthy/
unusable: G15 (just launched), G32 (reactivated), R24 (currently
tracked by only a handful of receivers). Currently inactive are: R02,
R03, R05, R18, R19, R22. G29 was decommissioned from active service on
day 296 (23 Oct 2007).
