With the networked SAPOS® HEPS, real-time positioning accuracy of 1-2 centimeters (location) or 2-3 centimeters (ellipsoidal height) can be realised. The correction data derived from carrier phase measurements are transmitted in a 1-second interval via the Internet (NTRIP) and mobile communications (GSM) in the standardised format RTCM.
By connecting the SAPOS® reference stations, distance-dependent errors are minimised and thus improved accuracy and reliability of positioning are achieved.
