How many different GPS satellite networks are there?
jacobica42 asked:
The United States has its network, and I think Russia has one too, but I’m not sure. Is that correct? Are there any private ones? How many are there altogether?

There aren’t any private ones. The Europeans will have the Galileo system, its is testing now.
By the way, the generic name is “satellite navigation”, or Global Navigation Satellite System (GNSS) .
As of 2009, the United States NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS. The Russian GLONASS is a GNSS in the process of being restored to full operation. China has indicated it will expand its regional Beidou navigation system into the global COMPASS navigation system by 2015. The European Union’s Galileo positioning system is a GNSS in initial deployment phase, scheduled to be operational in 2013.
