SATEL-TR4+ is a UHF data transceiver module in a lightweight single board structure. It is designed to be integrated into a host device, e.g. to transfer GNSS correction data in a land surveying rover or RTK base station.

  • 70 MHz tuning range (403…473 MHz) and selectable channel width (12.5, 20 and 25 kHz)
  • Extended operating voltage range
  • Moderate power consumption
  • AES128 encryption support as default, AES256 as an order option
  • Polling Protocol as an order option

Easy installation and configuration

SATEL-TR4+ is supplied without a housing in PCB format with RF-shielding, facilitating installation into the customer’s own housing or into a host device. The radio module configuration can be done with the SATEL SL-commands or SATEL Configuration Manager software.

Compatible and customizable

SATEL-TR4+ is compatible with widely used SATEL radios, such as SATELLINE-M3-TR4, -EASy, -Easy Pro and SATEL-EASy+, and also with other manufacturers’ radio protocols.

SATEL GO radio modules match all the needs of OEM customers. Please contact us or our nearest distributor for various possibilities to create a customized solution for you.
