Check known controlpoint with ntrip?

Hi there,

i just fixed the issue I had with not receving corrections via ntrip.
So now i get fixed solution in the field.
Should I still check my coordinates at a fixed known controllpoint?
I have seen some yt videos where people did that an had about 2m error when checking on this points. How could this happen?

Best regards.

Hello. by making a measurement on a known point, you can be sure that the GPS fits into the system correctly. please provide links to these videos. I will present my observations regarding the correct fitting of emlid instruments in work with ntrip in some time when I gather a lot of information on this subject, but I can say that I have had several cases where the fix coordinate was shifted by 0.8 meters.


Hi @Archeo,

If you work with an NTRIP service, such an error may appear because of different coordinate systems.

To not face this, make sure your NTRIP provider sends corrections in the coordinates system required for your Emlid Flow project. When you create a project in Emlid Flow and choose the coordinate system and vertical datum, there is a tip saying in which coordinate system the base should be.

If you need any help with that, please let me know.
