Hi,
I am looking for a GNSS correction service that I can access without a network connection, with a target accuracy of approximately 30 cm.
The obvious solutions are Galileo HAS or L-band correction services (e.g., Skybridge, Atlas), but we operate many receivers and replacing all of them is not financially feasible. We also frequently work in very rural areas with no cellular coverage.
What I am looking for is an external device that can receive and decode Galileo HAS and then output the corrections in an RTCM-like format over a serial interface or UHF radio, so they can be used by existing receivers.
Do you know of any such device?
Thanks.

Just take a static reading on a base point then use 2 units, Base/Rover.

@landbutcher464mhz Most of the time, there is no benchmark nearby. And my radios are limited to 1W so can't get good reception over 10 km.

Per Google:
"A 4-hour static GPS measurement, when processed correctly using survey-grade, dual-frequency equipment and post-processing software (like NOAA's OPUS service), generally provides very good, centimeter-level elevation accuracy."

A repeater radio broadcasting at 35w should give you 20+km of range. Beyond that RTK is not an option anyway.
