Sergio,
Thanks for providing more info about your workflow.
This is a good height for a survey.
A single-band receiver loses fix under trees because it doesn’t have enough signals from satellites in these conditions. That is why it needs a clear sky view to acquire a fixed status.
It’s probably a coincidence, but it’s great that you had a receiver ready to work just in time!
Emlid Studio
We recently released our post-processing software, the Emlid Studio. It is still in the beta-testing stage. The screenshots from my last post are from this software. You can try Emlid Studio by yourself.
You can easily inspect the raw data and process your logs there. You can check the workflow and download the latest version in our guide about the PPK workflow in Emlid Studio. A guide about the interpretation of the raw data and PPK results may be helpful for you.
It would be great if you’d check out a public thread about Emlid Studio to be up to date with the latest beta versions and new features.
