Hi All
I have been struggling a little lately . It seems that sometimes when i lose my RTK connection in the field , it will reconnect and show high accuracy …. But when i carry on surveying i can see a-shift in location of around 10 m and maybe 2 m in height difference . If i refresh the unit and reconnect to rtk it returns to the original survey datums ?? I understand that it is rtk but the softwares shows as full green fix with around 15mm accuracy as would be hoped for ( although its metres wrong )
All help hugely appreciated as it worrying me for future projects , Thanks Stu

Hi Stuart,
Good to see you back!
A 2-10 meter elevation difference indeed seems odd. Let’s figure it out together.
First, it’d be helpful to know if the discrepancy is consistent across multiple points within the same project. If it is, it might be related to a vertical datum mismatch.
Could you share how you determined that the points are off by that much? Are you comparing the points to known control points, or retracing the same spots over time and noticing the shift?
If possible, please send over your CSV and comparison data to support@emlid.com or via PM.
To help pinpoint the cause, I’d also like to better understand your setup. Are you using your own base station or an NTRIP service? If it’s the latter, which service are you using?
