Overview
Ready for the jobsite.
SATEL RTK Bridge Kit carries GNSS correction data from an internet NTRIP service into a local UHF radio network. The MCCU-20 receives corrections over LTE, then passes them to the kit’s radio for broadcast to compatible RTK rovers. This architecture extends precise positioning into areas where individual machines have weak or unavailable cellular service, without requiring a local GNSS base station.
The standard kit pairs MCCU-20 with the rugged SATEL Proof-TR489 for a compact 1 W installation. The extended configuration uses SATEL-EASy Pro+ for up to 35 W of transmitter power where local regulations permit. Both versions include cellular and UHF antennas, interconnection cabling, power leads and installation hardware; SATEL NARS-BT is available for optional Bluetooth configuration.
The equipment can be installed on a surveying tripod, a work vehicle or a fixed structure. Correct radio licensing, antenna placement, grounding, surge protection and power-system design are essential to dependable operation. Use the installation guide for configuration and mounting requirements.
