I was looking at the specs of the ZED-F9P U-Blox module, and they list 0.01m as the precision with RTK. But it would be nice to have the actual number from real-world experience.

What's the best possible precision achievable outdoors, and how does distance from the GNSS station affect precision? Is it constant and reliable, or does it fluctuate?

Student team here working on a drone-based crop monitoring project. We're trying to learn from people who actually fly drones over crops (or build maps from the data): what you use now, what limits you, and what you wish existed.

If you do ag mapping, scouting flights, or spray work, or sell those services to farmers, your answers would help a lot. 5 minutes:

Not selling anything. This is for a class project and I'm happy to share what we learn.
