Does entering the coordinates reported by the D RTK 2  into the advanced settings of DJI Pilot 2 - RTK settings screen help improve accuracy or repeatability on future missions in the area if I don't know the "real" coordinates?

Looking to use Mavic 3M + D RTK 2 station for field mapping/crop scouting.  Wisconsin has an NTRIP network available (WISCORS) but connecting to it seems to be an issue for me - maybe poor cell phone reception/internet in the boonies.  I ordered the D RTK 2 station and am trying to use it correctly.  From videos, it looks like I should always position the station at the exact same location each time I fly a mission in that area.  Would it make things more accurate or maybe more repeatable if I also entered the coordinates reported by the D RTK 2 in the Advanced Settings in DJI Pilot 2 RTK settingsthe 1st toime I set it up in an area when I don't know the real coordinates for that point?


Thank you,
Stu

If you have the possibility to do so, return this crap to where you bought it and ask for a refund. With the money, buy serious equipment from Emlid for example.

Otherwise yes when we do not know the coordinates, placing the antenna at the same position and entering the same coordinates each time (no matter what is displayed by the DRTK2) should theoretically work to ensure repeatability in the positioning of the raster.

But it is theoretical, it remains a DRTK2, which is the worst possible positioning solution.

Good luck.

Thanks for the comments on reliability!  Looks like is is going to be part of the cost of learning.  This is a sideline for retirement - not high volume but I do want accurate data for the folks that I work with.  I have time to see if this will be good enough and have the time to upgrade.

If you do the same field regularly, forget the DRTK2 setting, put it in broadcast random on the coordinates it chooses, wait for a FIX its important.
Place markers (GCP) on the ground around the plot. With paint it is quite effective.

The rasters will have an offset that corresponds to the DRTK2 error, but you will be able to align the rasters with the marks on the ground.

To get more at the root of your question, and agnostic to the RTK-capable GNSS unit used: If you want your imagery to be both repeatable (high precision) and accurate to real world coordinates, then having your local on-site base set up over precisely known coordinates is a best practice.
There are many ways to achieve precision and accuracy, but if your worlkflow involves setting up a local base station then having it on known coordinates is optimal.

Yes, the D-RTK 2 is a POS in many ways. Yes, there are other ways ("find the shift", PPK, use GCPs, etc.) to reach the goal. But if the question is whether or not it is better to enter known coordinates into a local base or not, doing so is generally better (assuming the coordinates are high quality).

As to whether entering the same lower-quality coordinates consistently on subsequent setups over the same point: yes, in theory that should help precision but not accuracy.

If you must use the D-RTK2, set it up at the very start of your arrival on site and let it start finding it's position. It's ok if you only want relative accuracy but as the two legends have already said, unless you can measure a precise location OR stand it on a previously known precise location, it's not great for truely accurate positioning. If you operate in the same place often, you might be able to get a friendly surveyor to shoot a point for you using their highly accurate GNSS reciever - you can then use that for the D-RTK2.
Don't beat yourself up though, I did exactly the same as you and LV quickly tuned me in. I now use an Emlid RS3 to both set GCPs and then act as base station for the drone - but it's expensive!!
If I had zero signal for streaming corrections, I'd probably use the Emlid to measure a point, set the D-RTK2 on that point, enter the custom coordinates into the RC and then use it for positioning. I might test that....
