External radio modems


Which external radiomodems would you recommend for the RS3? Must support RTCM v.3 protocol, and 419xxx freq’s.

Hi Fredrik,

I don’t have specific recommendations for external radios for your base. But just wanted to share this post about such integration and sum up the requirements from the Reach RS3 rover side:

  • Working on 410-470 MHz
  • Supports the Trimtalk protocol
  • Sending the correction in RTCM3 format

Perhaps our users can be more specific and share what radios they work with.
