Hey all,
I flew today using the D-RTK2 base and M210v2 RTK.
Using an X4S camera, I believe it does encode accurate coordinates to each photo..
Rundown of methodology:
* Coordinate base marker (Aluminium Plug In Conc.) using CORS corrected GNSS unit.
* Coordinate a few GCPs
* Export Base coordinates in Decimal Degrees Geographical (Lats/Longs)
* set up D-RTK2 base and turn on.
* measure height of D-RTK2 pole + add the 142mm for antenna.
* turn on M210v2 RTK and Pilot App (CS)
* wait for “RTK” setting to change to “FIX”
* Change D-RTK2 coordinates to my new ones via the advanced options tab.
* save this change, reboot M210v2RTK
* wait for re-initialisation of M210v2RTK.
* set a waypoints mission (mapping) via Pilot app.
* choose camera (I had to enter a custom one for the x4s - had to search internet for all the random specs.)
* choose the overlap and all the usual..
* fly as usual.
Now, with regard to the post flight..
I need to look to see where to find the RINEX data which DJI say should have been written for the flight.. (not sure given I didn’t use the x7)
- when I dropped the photos (straight off the SD Card) into a Pix4D project, the photos had GPS accuracies under 0.1m. And when I processed the data, final output numbers were sitting at XYZ
I’ll re-process and check all the options and settings again tomorrow (a-bit distracted this afternoon) just to ensure it wasn’t a lucky click..
Ultimately, this was just a quick 12min flight, ~220photos and 5 GCPs, over 200sqm..
When the weather improves later this week, I’ll have another crack and see how it performs.. might extend to a larger area/GCPs/check points.
But, all in all.. happy with initial data.. flight planning in Pilot could be better.. (All functional DJI cameras should be choosable)
Will keep you all updated.. see how it goes..
