Which is it, GPS, GlONASS or GALILEO?

Does anyone know if the Evo 2 chip uses data from all 3 of these or just the US GPS satellites. Curious as I was using the UAV Forecast app and it showed 17 satellites visible with GPS and GlONASS on. When I included Galileo, 22 showed visible. I then used my IPAD with the previous version of Explorer, (still showed the actual number of Satellites, now since upgrading, only see the bars) and could see 18 on the Explorer App. I can assume that the Evo 2 chip therefor sees all 3 countries sats. Anyone have thoughts on this?
