How does all of this work???

Infrastructure The future of the Survey, Mapping and Construction industries.

Server: Central Data Management Infrastructure Server: Central Data Management

Data Flow Reference Station data streams back to server through LAN or Internet

Data Flow Roving receiver sends a NMEA string back to server using cellular modem - VRS position is established VRS NMEA - GGA

Data Flow Server uses VRS position to create corrected observables and broadcasts to rover VRS RTCM or CMR+

Data Flow Rover surveys as in normal RTK survey but getting data as if coming from the VRS VRS

VRS - How does it work? Network Processes Integrity monitoring Geometric correction Correction for tropospheric errors Correction for ionospheric errors Ambiguity resolution Consistency check Delivery of VRS corrections to your mobile location.

Network Multiple Base Station Solution Let B1, B2 B3 be base stations, R be the rover   B1 B2 R B3 Four RTK engines run simultaneously: (1,2) (2,3) (3,1) (1,R)+(2,R)+(3,R)

What’s the advantage???

Advantages of VRS Eliminates dependency on single reference station or base station. Uses established communications. Establishes a single coordinate system.
