Dear colleagues, 
 
The GLONASS tracking problems reached in the course of D171 a point  
which is more than alarming. We had to stop orbit determination with  
respect to an active GLONASS satellite just because of a lack of IGLOS  
tracking data! Only five IGLOS stations, 
 
  dwh1, 
  khaj, 
  os0g, 
  spt0, 
  zimj, 
 
are currently able to provide R08 tracking data. All other IGLOS  
stations, 
 
  bogi, 
  cagz, 
  conz, 
  darr, 
  davr, 
  drej, 
  ffmj, 
  godz, 
  gope, 
  helj, 
  hert, 
  hueg, 
  irkj, 
  joz2, 
  kr0g, 
  lhaz, 
  leij, 
  mat1, 
  metz, 
  mr6g, 
  mtbg, 
  mtka, 
  ohi3, 
  reyz, 
  thu2, 
  titz, 
  unb1, 
  wroc, 
  wtzj, 
  wtzz, 
  yarr, 
 
seem to simply ignore this transmitting GLONASS satellite:
