Hi there,
I'm flying my new M4E in GDA2020 / Zone 54, getting corrections from the government NTRIP service (baseline about 10kms).
I have flown this site many times with my P4RTK and have just rechecked the permanent GCPs, I've never had any issues.
I'm getting large variations in the results from the photogrammetry, so much so that I borrowed another M4E to check and it behaves the same. See RMSE values below.
I'm connected via starlink and it says fix for the full flight. The flight settings were the same between the three drones, overlap, height etc.
I have run this through in Terra and Virtual surveyor, both show large inaccuracies in the M4E location data.
Has anyone else run into this type of problem? I've attached a screenshot of the RTK data in the M4E while it is saying 'FIX', but there is a large variation...

The RMSE of each flight is detailed below:
P4RTK: 0.013m
Hire Drone (M4E): 0.313m
My M4E: 0.218m
