This satellite is already included in the analysis scheme at
CODE. Starting with our day 292 rapid and day 293 ultra-rapid orbit
submissions, the CODE GNSS orbit products now include 54 satellites (31
GPS plus 23 GLONASS). G24 is unoccupied, G27 is marked unhealthy; R03
is temporarily unoccupied (occupation by former R04 to be expected),
R04 is marked unusable.
