Receiver module


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).

Fits for your needs

Please contact manufacturer to have information on available interface and antenna connector options.

The module can be manufactured with an AES128 encryption support on the air interface to ensure the privacy.
