Product Description



Industrial UHF/VHF Modem

Dual-technology RTK transceiver for receiving the GNSS RTK correction data.


The SATEL MCCU-20 LTE / UHF is a unique dual-technology RTK transceiver for receiving the GNSS RTK correction data to a moving vehicle with UHF radio based RTK or NTRIP over LTE. The RTK correction data is forwarded over RS-232 serial communication to machine control system.


Connectivity in harsh environments

The MCCU (Mission-Critical Connectivity Unit) platform is designed to resolve connectivity challenges in harsh environments. It delivers mission-critical signaling from relatively small machine control messages with constant latency to wideband and low latency camera stream. The SATEL MCCU-20 LTE / UHF has IP67 and IP69K classification and it withstands vibration and shock. It is based on field proven mechanics, and all the electrical connections are equipped with surge and ESD (Electrostatic Discharge) protection.

Easy integration

The machine and vehicle manufacturers and machine control system providers can integrate SATEL MCCU-20 LTE / UHF to their offering without knowing what kind of technology is available in the operating area. The vehicle can be operated under varying connectivity environments.

Mission-critical connectivity

  • RTK correction signaling for centimeter level positioning accuracy
  • Collision avoidance signaling (CAS)
  • Machine to machine commands (V2V also V2X)
  • Secure firmware updates
  • Central control signal
  • Safety signaling
  • Mission-critical telematics Type approvals for main markets are to be carried out.
