However, no correction is applied, FIX is not reached. How is this? I even tried to use the mapping intermediant station as suggested ( SSR2OBS ), as the format might be a problem.
I also switched “send NMEA GGA” on and off, no difference. I also don’t get FLOAT, there are no grey bars next to the satellites.
I too tried to update the firmware to the newest beta, to no effect.
The correction in the Emlid Flow app (status page) are shown to “receiving corrections” but it keeps displaying initial value is 0, no initial position, no satellites displayed (even though > 30 satellites have been found).
We haven’t tested this ourselves, but this is what we see on their webpage:
“The new SSRZ correction data format cannot currently be processed by commercially available GNSS receivers. To still use the service, a special software package called SSR2OBS can be used. The software converts SSRZ data into OSR data, which can be processed by GNSS receivers.”
Our receivers need the RTCM3 format to be able to calculate the corrections. Worth a try to reach out to the NTRIP provider and ask, if it is possible to convert the SSRZ format to RTCM3.
You just have the wrong source, as Zoltan says SSRZ is incompatible. It’s a new complex currently scientific only format.
SAPOS traditional NTRIP with RTCM3 is readily available across Germany but it’s administered and delivered by the individual states.
For example, I have a free account with Thuringia that provides RTCM 3.2 VRS but haven’t tested it as I won’t be there until later in the year and delivery is also geo-fenced to within that state border only.
So you need to make sure the NMEA output is on, so it knows where you are, and location is also needed for a VRS solution anyway. Other states may be different; I haven’t blundered about in them yet.
Which state or states do you need it? I can try my best Aussie-German interpretations to locate the relevant application site for you.
Edit: You can find the state operator sources listed here: https://sapos.de/
And the standard RTK service you need is called HEPS
