## Overview

SATEL MCCU-20 is an all-in-one GNSS RTK correction receiver for machine control, precision agriculture, surveying and other positioning applications. It can receive correction data from a local UHF base station or connect to an internet NTRIP caster over LTE, then forward the data to the host system through RS-232.

The two connectivity methods are selectable operating modes rather than simultaneous links. UHF supports work in areas without dependable cellular coverage, while LTE provides access to network correction services where coverage is available. In NTRIP mode, the built-in client can send the vehicle’s NMEA position to compatible casters and pass received correction data to the host without modifying the payload.

The aluminum enclosure and mated connectors carry IP67 and IP69K ratings. Power, serial and RF connections include surge and ESD protection, and the UHF path includes GNSS-band filtering. An ignition-sense input, wide DC supply range and Deutsch power/data connector support installation on vehicles and other mobile equipment.
