GLONASS-714, a GLONASS-M satellite launched on 28 Feb 2006 (as R23),
has been reactivated (as R06). "All-in-view" tracking stations of the
IGS tracking network have been receiving its signals since day 118
(28 Apr 2010):

Remark: The reported GNSS tracking failure concerning Leica GNSS
receiver models seems to be related to this GLONASS satellite
reactivation.

This reactivated satellite is already included in the analysis scheme
at CODE. Starting with our day 119 12UT ultra-rapid and day 119 rapid
orbit submission, the CODE GNSS orbit products now include 52
satellites (31 GPS plus 21 GLONASS). G01 is marked unhealthy, G25 is
unoccupied; R06 is marked unusable. Once more, it should be emphasized
that current data of R09 (722) is considered useless and is therefore
generally excluded from our analysis.
