Yes, if you just use the DRTK to obtain its coordinates while not receiving corrections or being placed on a known point, your absolute accuracy will be bad. It could be inaccurate as measured in meters.
Your relative accuracy will still be very...
The accuracy is lower with the D-RTK-2 at any random location close to where you are working. Exactly how much depends on a whole lot of factors. If you place it on a known control point, it gets a lot better, down to 5 cm I believe. There are a...
You will need to receive corrections from:
1. DRTK 1 or 2, Emlid GNSS Receiver - both on a known point. (Your accuracy will be as accurate as your known point. An NGS monument or surveyed point can also work well.
2. A corrections service such...
The Mavic 3E (M3E) is an excellent mapping drone.
With the RTK module and using NTRIP you can obtain low centimeter accuracy/precision without any GCPs as long as you don't just use nadir images. The M3E also has a mechanical shutter so you can...
