SATELLINE-M3-TR4 is a flexible UHF data transceiver module suitable for different uses. It is an updated version of M3-TR3 module with two modulations more 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.

  • 70 MHz tuning range (403…473 MHz)
  • Selectable channel width 12.5 and 25 kHz
  • Low power consumption


Easy configuration and wide compatibility

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).


Customizable for your needs

In SATELLINE-M3-TR4 the mechanical fastening and its type, interface and antenna connector types can be customized upon request. For large orders also the shape of the PCB can be customized. The module can be manufactured with an option for 128-bit encryption on the air interface to ensure the privacy.
