The new GLONASS-95 satellite, which is now included in the list of GNSS satellites to be tracked by SLR, is one of two new GLONASS-M type satellites. The fact that GLONASS-M represents a third GNSS model generation equipped with LRA makes this particular satellite very interesting for SLR and microwave analyses. The mentioned GLONASS-M satellite is already considered in our SLR Quick-Look analysis (labeled with R07 in the daily reports). CODE uses to perform POD (and associated orbit prediction) for the complete GNSS constellation as long as simultaneous microwave tracking data is available from at least two ground stations. For R07, still marked unusable, this is currently not the case (very probably due to extra testing, or calibration). We start from the assumption that the situation will improve within one or two weeks. Declaration of R07 as ”operational” may be expected by the end of this month.
