SATELLINE-M3-R4 is a flexible UHF data receiver module suitable for different uses. It is an updated version of M3-R3 module with two modulations (16- and 8FSK) 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.

  • 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-R4 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-R4 the mechanical fastening and its type, interface and antenna connector types can be customized upon request. The module can be manufactured with an option for 128-bit encryption on the air interface to ensure the privacy.
