Need for base station?

Michael,

Sorry for the delayed comments.

@mlangford

So, if I’m just using a rover receiver (say an RS3), then I am required to have access to a local NTRIP service provider to get accurate georeferenced data points?

Yep. You can work with real-time corrections or, as @daygeckoart mentioned, in PPK. For the latter, you’ll need to process the logs from the drone and the logs from the NTRIP service.

@mlangford

But if I’m not using a local NTRIP service, am I still able to obtain relative accuracy instead? Especially if I set my first data point as a zero benchmark point and take further levels using your Castor of Flow apps?

Emlid Flow doesn’t support working with arbitrary coordinate systems for now. But you can use localization to work in a coordinate system with a false origin. It’s possible both when you receive corrections from the NTRIP service or your own base. Here is a post to learn more about the workflow.
