GNSS (global navigation satellite systems) (GPS is GNSS)
GPS (Global Positioning System) and RTK (Real-Time Kinematic Positioning)
As of 2019, there are three functioning GNSS systems, US NAVSTAR GPS, Russian GLONASS, and Chinese Compass BeiDou. There is a fourth one with 30 satellites, called European Galileo, that is nearly fully operational
