SATELLINE-M3-TR3 is a UHF data transceiver module in a lightweight single PCB structure. It is designed to be integrated into a host device, for instance for transfer of GNSS correction data in a land surveying rover or RTK base station. 1W output power in conjunction with a very sensitive receiver is the guarantee of a reliable data connection.

The configuration can be done by using the SATEL SL-commands or SATEL Configuration Manager software.


Wide tuning range and selectable channel width

  • 70 MHz tuning range (403…473 MHz)
  • Selectable channel width 12.5 and 25 kHz
  • AES128-bit encryption available for secure transmission
  • Low power consumption
  • Supplied without a housing in PCB format with RF-shielding, facilitating installation into the customer’s own housing or into a host device

SATELLINE-M3-TR3 is compatible with widely used SATELLINE-EASy radio modems and also with other manufacturers’ radio protocols (Pacific Crest-4FSK, -GMSK, -FST).


Customizable to meet your needs

To ensure the privacy, SATELLINE-M3-TR3 can be manufactured with an option for 128-bit encryption on the air interface.

In the radio module the mechanical fastening and its type, interface and antenna connector types can be customized. Also the shape of the PCB can be customized for large orders. Please contact us to learn more about the customization options.
