I’m interested in trying to use GCP and/or RTK/PPK to increase the accuracy of my maps to within at least 5cm, maybe 3cm. Are there any inexpensive solutions for this? UAV-mounted RTK devices, high-accuracy GPS devices to pinpoint GCP placement, etc.
there are some somewhat inexpensive RTK gps devices you buy nowadays. I feel the least expensive of them all would be the ublox zed f9p module which you can get from either spark fun or ardusimple. I personally own a ardusimple rtk kit and it works well using NTRIP for corrections I can get 5cm accuracy… also there is the EMLID line of RTK modules, but will be a bit more pricey. not sure of ppk kits of mavic 2 however.

I wonder if RTK modules added to the UAV w/out GCP is as accurate as a ground-based coordinate finding system w/ GCP. I mean, I understand that attaching RTK to the drone would be easier, but if creating GCPs with a rover or something would be better, I’m not against it if it might require less capital.
Havent had the chance to read it through but this may shine some light.

Uplanddog, are you using the f9p chip in a Drotek head or on its own? I he been struggling with trying to get the Drotek head programmed on u-blox for use as the base against a Yuneec H520E - RTK.
No. i use an ardusimple board with the f9p to geolocate ground control points.
