New receiver module



SATEL-R4+ is a new UHF data receiver module suitable for different uses. 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
  • Extended operating voltage range
  • Moderate power consumption
  • Models with AES encryption support available

Easy configuration and wide compatibility

The radio module configuration can be done with the SATEL SL-commands or SATEL Configuration Manager -software.

SATEL-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.
