  • Page 5: Overview

    The Intuicom Wireless RTK Bridge - Cellular expands access to GNSS network RTK corrections for rover users in the field. The RTK Bridge - Cellular combines an embedded GPS and cellular (CDMA or GSM/GPRS/EDGE) Internet connectivity with an Intuicom Wireless Data Radio with to support a wide range of deployment configurations.

  • Page 7: Example Applications

    Typical installations have the RTK Bridge configured to connect to an NTRIP Caster where it provides mountpoint and authentication information. Once connected to a mountpoint, it will stream its GPS point position (from its internal L1 GPS) allowing the Network Correction Server (such as Leica Spider) to generate individualized corrections or create a virtual reference station.

Users simply connect a third party base radio to the Data Out port on the front of the unit to broadcast a copy of the correction stream.
  • Page 9 Bridge. Furthermore, if the distance between the RTK Bridge and the rover users is great – the RTK Bridge can be configured to report its position to the GNSS Network server as if it were in the location of the rovers – further optimizing the network correction generated by the GNSS network server.
