  14. How does all of this work???

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

  16. Infrastructure Server: Central Data Management

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

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

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

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

  21. 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.

  22. 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)

  23. What’s the advantage???

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

  25. VRS & You Questions???
