  • GPS (USA) - 75 Global Positioning System navigation satellites have been launched, 31 of which are operational, 9 in reserve, 3 being tested, 30 have been retired and 2 were lost at launch

  • Beidou (China) - 42 or 35

  • GLONASS (Russia) - 128 reached the correct orbit and 24 are currently operational

  • GALILEO (EU) - 26 Galileo (and 2 GIOVE) satellites have been launched, 22 of which are operational, 2 being tested, 2 (the GIOVE) have been retired and 2 were unavailable.

  • NAVIC (India) - 7

  • QZSS (Japan) - 4

Total operational: 92 + 35/42 = 127/134

Are there any more such satellites? Maybe for military purposes

    $\begingroup$ You may have missed QZSS. Of course there may be other I don't know (otherwise I would have post an answer). $\endgroup$ – Manu H Aug 6 '20 at 14:55
  • $\begingroup$ My bad sorry. I was thinking about those dedicated exclusively for military uses $\endgroup$ – Joe Jobs Aug 6 '20 at 14:56
