I have been running a reach PPK system on a UAV and I am struggling to get accurate results, with offsets circa 2m when comparing against checkpoints. The offset across a project is typically 2m in y, 0.3m y and 1m z. The offset is roughly constant across a project… so its like its a fixed error??
Im sure it is an error somewhere due to processing but I am at the limit of my understanding and looking for some suggestions.
I am experienced with PIX4D and confident that its not the photogrammetry processing causing the issues.
The base (reach RS+ is positioned over a known survey point (sub 10mm accuracy).
Survey point coordinates (+53.60437489, -1.0291630077, 54.750)
The RS is mounted on top of a 2m pole with the brass adaptor (I believe this is 22mm)
The M+ antenna is mounted on a ground plane, 10cm vertically above the sensor origin.
I am following the PPK processing document from the Emlid website.
If its of any help, please see link to UBX data:
When processing I am inputting the base coordinates into RTKPOST as well as the antenna offsets.
Welcome peoples thoughts.
