iMAR’s iRRR is a robust, high performance RTK GNSS Base Station dedicated for stationary installation within a 19” rack for professional applications. The iRRR’s integrated GNSS receiver operates in Fix Position Mode and generates RTCM correction data in comparison to its known position.

The iRRR provides RTCM RTK correction data streams via VHF/UHF radio modem output by integrated field proven SATEL Radio Modems as well as via UART interface. These data, generated by the integrated all-constellation / all frequencies GNSS receiver, can be forwarded via the integrated NTRIP Caster as well as via an external one.

As a special feature, the iRRR can be equipped with up to three simultaneously operating dissimilar redundant (!) high performance GNSS receivers – it is the leading hardware solution to mitigate well-known impacts from common mode failures (in usual standard setups known from other manufacturers, only one or several identical GNSS receivers  are operated and common mode failures in the RTK correction data cannot be detected).
