SATELLINE-M3-TR4 is a flexible UHF data transceiver module suitable for different uses. It is an updated version of the M3-TR3 module with two modulations to give added speed to the radio interface. The radio module is easy to integrate into a host device, for instance, GNSS correction data transfer in a land surveying rover or RTK base station. The radio module configuration can be done with the SATEL SL-commands or SATEL Configuration Manager -software.

SATELLINE-M3-TR4 can be added to existing systems; it is compatible with widely used SATELLINE-EASy radio modem family members and it supports also other manufacturers’ radio protocols (such as PacificCrest-4FSK, -GMSK, -FST).
