There are quite a few alternative systems that provide the same functionality (http://en.m.wikipedia.org/wiki/Global_Positioning_System#Other_systems http://en.m.wikipedia.org/wiki/Global_Positioning_System#Oth...). Most aren't global, but the Russian one is, and the Chinese and EU ones are planned to be one. Many phones can use GLONASS, the Russian system, so, for example, the 'GPS' in your iPhone or Lumia may not always be using the GPS system to compute your location.
