"All-in-view" tracking stations of the IGS tracking network have been receiving its signals since day 118 (28 Apr 2010): http://www.aiub.unibe.ch/download/igsdata/y2010/odata_glonass_d118.txt http://www.aiub.unibe.ch/download/igsdata/y2010/odata_glonass_d119.txt 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. The CODE AC Team
