I emailed them. They said SBAS correction would only work with an internet service. It is pretty much useless as a standalone.
Hi Michael,
Julie is here. Thank you for reaching out.
Reach RX was designed to work as a network rover. So the only way for it to get the corrections is via NTRIP. It can be a correction stream from an NTRIP Service or your own base. It’ll allow you to work in RTK and achieve centimeter-accurate coordinates with the receiver.
Reach RX tracks signals from SBAS satellites. However, it uses them for RTK only, as it can’t read the corrections info from the signal itself. That’s why the accuracy of the receiver in standalone mode is several meters.
If you want to work with the receivers in areas with no cellular coverage, I recommend you take a look at Reach RS2+. They are also multi-band but support passing the corrections for RTK via radio as well. So it may be an option for you. Here you can find the comparison of Reach RX and Reach RS2+.
Feel free to ask me if you have any additional questions.
