GPS Rover and Base sets
RTK GNSS rover and Base sets are mostly used in rural areas. When you have no access to local correction services or when there is poor internet reception, a rover/base setup is the way to go. The base acts like a remote base station which you can setup to receive RTCM correction data from. This is send via UHF radio to the rover receiver. Most GPS receivers have internal radio modems variating from 0.5W all the way up to 5W. For a higher output an external radio is recommended. The rover is used for surveying purposes like point collection or stakeout.
