How does all of this work???
Infrastructure The future of the Survey, Mapping and Construction industries. The future of the Survey, Mapping and Construction industries.
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 NMEA - GGA VRS
Data Flow Server uses VRS position to create corrected observables and broadcasts to rover RTCM or CMR+ VRS
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 monitoringIntegrity monitoring Geometric correctionGeometric correction Correction for tropospheric errorsCorrection for tropospheric errors Correction for ionospheric errorsCorrection for ionospheric errors Ambiguity resolutionAmbiguity resolution Consistency checkConsistency check Delivery of VRS corrections to your mobile location.Delivery of VRS corrections to your mobile location.
Network Multiple Base Station Solution B1B2 B3 R Let B1, B2 B3 be base stations, R be the rover Four RTK engines run simultaneously: 1.(1,2) 2.(2,3) 3.(3,1) 4.(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.
