So what does my Chinese made drone actually send to the CCP? An Ortho mosaic of a typical warehouse construction site? I guess it is better quality than what is already available on google earth. We can't fly in restricted military airspace as it is so why shut down all use of a quality product?

I recently prepared a proposal for an EPA site that specifically says "no foreign made drones" can be used on site. Makes no sense since most of our surveying gear is also foreign made.

That is a safe move and one I wished I had done at first. Autel did give me a way to go back to a usable version which is what others have done. Since then, the smart controller upgraded to a newer stable app version which does have the Corridor mission and smooth controlled turns which I wanted...

So your version of the app does not have the Corridor Mission? It was implemented in the past year and other than a few problems with current version of firmware, it is working pretty good. I have been able to upload a kml file and run the Corridor mission without issues since. I run the SC 2...

I have been a surveyor most of my life so traverse points and monuments are like oxygen to me. Every site we work on has good control, so some of those then become GCPs. The limited testing I did early on when I got the drone using RTK only was a mixed bag of success and troublesome data. So...

Sorry to hear that, must be specific to that unit. Other than the latest firmware update headache, our V2 has been pretty reliable. I have noticed a drift or fold so to speak of the final ortho along edges that did not have a GCP close by. But the elevations have been consistent with typical gps...

Are you using ground control points to process your images?

Is the drone outside? Unfortunately, RTK network services only work outside with clear sky. The drone RTK will need to receive the corrections from the network through the smart controller but still needs clear open visibility to the satellites.

You do need a real time network provider for the RTK if you are not using a separate base station. We use Smartnet but it is a yearly subscription of $2400. You can find your local state DOT networks which I know here in MA is free. The stations in the MADOT are spread out and not as dense as...

It's odd Emlid does not give you that option. Most RTK GPS units today easily transform between datums. It's a matter of being careful what you enter. When we get control coordinates from another surveyor, we check it right "out of the box" with our system and if we see a difference of...

See if you can do a reverse through https://geodesy.noaa.gov/NCAT/ You will need to know your zone

Possible. I know I have had weird things happen under high tension lines, but that was back when I was using early version of UHF gps base.

Try different mount point. When I switched mine I got quicker fixes. I went from RTCM_NEAR to MSM_IMAX.

I did a reinstall and same issues with app crash. Autel support came back with a link to the "beta" version which I installed but still end up with app crash issues. What is interesting is the version number they sent seems to be increased in sequence (Explorer_V2.0.24-tablet7_9-release) Not...

I submitted a support request too. They said their engineers are working on it.
