I’ve been using the Reach RS2+ on some recent survey work, and while it does great with NTRIP, I’m having issues with LoRa corrections. Base and rover at about 700 meters (open shot), I’m dropping fix or floating too often. Locking back up to fix takes several minutes, and this kills my productivity.
I’ve checked antenna placement, updated firmware, and played around with LoRa frequencies and air data rates — still no solid improvement. I’m wondering if it’s a configuration detail I’m overlooking or maybe external interference?
Also, as someone coming from a DevOps background, I’ve been documenting this experience as part of a larger DevOps Tutorial I’m putting together on integrating GNSS data into automated workflows. Any insight from the community would really help make that guide more robust and beginner-friendly.
Has anyone run into this and found a stable setup? Would love to hear how others are managing LoRa connections reliably in the field.
Thanks for sharing all these details. I agree that 700 meters is quite a short distance for LoRa. Let’s go over the setup together and see what might be happening.
To start, would it be possible for you to share a photo of the environment where you’re surveying? Since LoRa is a low-power radio, it’s pretty sensitive to environmental conditions. There is a need for a line of sight between the base and the rover, and the absence of any other electrical disturbance.
To check this in more detail, I’ll need some raw data logs from your units:
Update your RS2+ units to firmware version 33 Beta 3. This version adds a radio signal strength indicator that might give us more clues.
Once you replicate the issue, finish logging, download the logs, and generate a Full System report. As the files are sensitive, please send them to support@emlid.com. I’ll review everything in detail to check what your rover receives.
I’d also like to mention another alternative. Since you noted that NTRIP works well for you, you could also consider using our free Emlid Caster. It transmits corrections over the Internet between your base and rover. This setup can be reliable in areas with good cellular coverage.
