Thanks for watching!

Thanks for watching. This is something we plan to do. We will eventually have another video for in depth processing.

no problem!

@@TerrestrialImaging I would just add one info here, if you’re trying to activate d rtk2 for first time sometimes you may need to update it to the last version 1) connect the d rtk to the laptop( cable in the box) 2) download Dji assist 2 (enterprise) 3) you suppose to see the d rtk2 in the app and should be good to update to the latest version

@@egorchorniy346 All good points!

Check out store.terrestrialimaging.com. We have a few different storage options for the D-RTK 2.

Thanks for watching! The camera on the M3E is great for that and you are correct, the RTK module is not necessary for progression pictures.

@@TerrestrialImaging Right on, I can save 700 bucks. Thank you!!

@@TerrestrialImaging would you say its necessary for construction progress and initial site reports for larger projects? Would it be useful to prevent warping without the need of setting up dozens of GCPs?

Hi Matt, yes you can still fly with RTK enabled even if you aren't flying an autonomous mission. You would do all the steps in this video except you would just be flying manually!

Hey Keith, hope all is well! Thanks for watching. All Typhoon related parts that we have can be found on our store, store.terrestrialimaging.com/search.asp?keyword=typhoon&search= When it comes to the drone itself, we not longer sell Yuneec drones.

Hey man i know you asked this a while ago, but NEVER do a RTK flight without at LEAST 4 GCPs if it is for anything commercial, esp construction related. Preferably 5 GCPs, 4 corners and one in the middle. If you dont do this, you will have huge data loss due to inaccurate measurements. I have tried everything under the sun to avoid doing GCPs, but they are absolutely essential, even with RTK base stations. When i only used the DRTK-2 with no GCPs, it put my entire jobsite off by 1 foot vertically. We ended up just going with a Topcon network subscription because the DRTK-2 wasnt giving us very accurate results, but im sure there has to be something i was doing wrong. For reference, im a full time drone pilot in the construction industry

Google earth satellite imagery is not as accurate as most people expect it to be, and sometimes can be multiple meters off. There is areas though when it could be tighter. The drone imagery collected during the flight is also referencing GPS data collected from the time it was flown where the GPS data from google earth might be a bit older. You shouldn't really expect the google earth data to perfectly line up with your drone data. DJI terra costs $4,000 USD for a perpetual license and If you wish to pay annually it is $1400 USD

I've never tried it with photogrammetry but I have done it with the L1. You have to take your ppk rinex file and name it with a specific naming scheme. From there you would include it in terra and your good to go.

12km or 7.5 miles. This is in perfect conditions with no obstructions. Thanks for watching!

Thanks for watching!

So, there is no additional costs or subscriptions. You will pay $3,600 for the RTK device and $250 for the tripod. From there its plug and play forever. The purpose of it is to utilize two GPS systems in order to make sure your drone is writing the most accurate GPS meta data to the images you are taking. DJI says that if the base station is on a known point, you can expect an absolute accuracy of 3cm and you can achieve this without ground control points, however, on a surveying job I reccomend GCPs Thanks for watching!

@@TerrestrialImaging Awesome. So what GCPs do you recommend? And for really large swaths of land how many would you recommend?

@@baileystark7629 www.amazon.com/gp/product/B07PHLYTCS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 These are affordable enough and get the job done. And I dont really have a true formula, but Id want a minimum of 3. One at the highest point, one at the lowest point and then one somewhere in the middle. But 3-5 should suffice. Again these have to be put on a location that you or a surveyor has marked. These do nothing if you just toss them on the ground.

Thanks for watching! The DRTK-2 will work outside of cell range, however if you wish to use NTRIP (receiving RTK over the internet) you will need cellular/wifi in order to do so

@@TerrestrialImaging awesome thanks!

@@TerrestrialImaging thank you for your video. I'm about to buy the Mavic 3E with an RTK unit, but I work in remote areas 100% of my time (no access to internet) I just wanted to be triple sure that ; 1. I should be able to use the RTK module connected to a D-RTK 2.0 station WITHOUT internet, and connection will be fine, right? and 2.- I noticed in your video how important was the stability of the RTK station, do you know if it works from Boats or Vessels (which are in constant motion?) thank you so much.

@@BorrasRenato 1) The D-RTK 2 can be used without internet connection. 2) The base station will not help if it is in constant movement. It is not supposed to be moved at all and ideally should be on a known point. Please reach out to our team at terrestrialimaging.com if you have more questions and need help purchasing the right equipment.

This is true! For absolute accuracy purposes you would set the DRTK-2 on a known point and then input the coordinates and height offset in the RC. For this video we were demonstrating a general workflow purpose for the DRTK-2 and M3E so people can can an idea of what the general setup and workflow feels like. Anyone using this for survey grade accuracy would input the known point

This for the tripod: store.terrestrialimaging.com/dji-d-rtk-2-tripod-bag And we have now switched to using this case for our M3E: store.terrestrialimaging.com/dji-mavic-3-enterprise-surveyor-case-for-dji-drtk-2.html

@@TerrestrialImaging at 1:01 in the video you are using a case with the tripod and the DRTK2 base station but that's different than the links above.

Hello! Yes you can, you just have to make sure your Emlid base station is set to Local NTRIP mode, at which point on your controller you will have to connect via custom rtk network. You will have to use all of the connection paramaters seen on the emlid app

@@TerrestrialImaging Nice I will try, Thanks Chris.

Dewarping is suggested to be turned off, because enabling dewarping may lose some information on the edge. DJI Terra prefer original photos to create mapping result.

The DRTK-2 can not be used to create GCPS. For this, I would reccomend the Emlid RS3 for its price point and ease of use. The Emlid RS3 can set GCPs, Check points, Known points, and can be used as an RTK base station.

Im sure you have learned the answer by now as this comment is older, but you would need someone to get a point for you, or use the Emlid to get the point. The emlid can sit on a point for a minimum of 4 hours, and then you can run that data through OPUS to get a known point. If you do not have a known point everything will be relatively accurate but not coordinate level accurate.

The Emlid offers more, as it can be used to mark GCPs. The DJI DRTK-2 is super convenient. Just turn it on and go for the most part.

Hey sorry we must have missed your message. It can work with any Mavic 3 Enterprises series drone so long as that drone has an RTK module attached to the PSK port on top

So long as your base station can output RTK corrections over Local NTRIP, you can!

If your device is able to cast RTK data locally, and have a connection based on a mount point, ip, etc. It should work.

That hardcase is a nanuk hard case! Sorry for the delay!

When setting up the base station you need to do 2 things: 1. Put it on a known point for absolute accuracy. If it is not on a known point you will only have relative accuracy, meaning everything in the ortho will be accurate relative to other things in the ortho, but not exactly accurate from a coordinate stand point 2. You need to get the Z coordinate for the known point and go into the rtk advanced settings, and set the height of your pole by adding 1.801m + Z coordinate height in meters. Your coordinates need to be in WGS84 format when using the DJI base station

@@TerrestrialImaging thanks for help

@@BNIRc, no problem!

We are using the Pilot 2 app for mission planning which is the default app to control the M3E. No promises, but we may make another video going into more detail. If you are interested in buying, please reach out to our team and we'd be happy to answer all of the questions you may have.

This video was to demenstrate the workflow for using the RTK module. GCPs will always increase your accuracy so we reccommend using them on a real job whenever possible

@@TerrestrialImaging Excellent. Can you show a full workflow of how all of that is connected. Really trying to gather the entire process

@@roymercer22 It is definitely on the list of videos to make!

@@TerrestrialImaging I'll be looking for it. Thank you for the response.

Yes, we have them in our store. store.terrestrialimaging.com

One D-RTK 2 Mobile Station can link with up to five remote controllers

Do you mean like without the DJI D-RTK2? This drone requires RTK data to perform an RTK flight. It would need a base station/NTRIP account/3rd party base casting locally

@@TerrestrialImaging thanks for the response. So without a base station the flying with rtk module on drone is useless?

@@Kumarswamy_Hosmath Correct. The RTK module does absolutely nothing without an RTK connection to a base station, NTRIP, etc. As a matter of fact, with RTK toggled on, the drone will not even take off and fly without a connection to an RTK service.

@@TerrestrialImaging i am still left some doubt on "connection"....... The source for connection HAS to be RTK Base station? NTRIP or any other services are accessible through internet connection?

@@Kumarswamy_Hosmath Correct the source is any device that can cast RTK data (a base station, NTRIP, etc)

the ground station is $3,600 and the legs for it are $250, the drone itself is anywhere from $3,500-$5,000 depending on number of batteries and other accessories, care policy, etc
