Great video, thanks for the info. A couple of questions: I've read in some forums that the accuracy of the handheld mode (3) is not really good. Have you had any problems? Is the D-RTK 2 able to communicate with other GNSS? such as Emlid RS2? Do you know if it's possible to use it as a rover (handheld) while receiving corrections from an RS2 base or vice-versa? (use D-RTK 2 as base to send corrections to RS2).

@prodronesasia5262 Жыл бұрын

We haven't had accuracy issues per se but the usual complain is slow to fix. The DRTK2 does not communicate directly with anything except the remote control. So as long as there is a way to connect the remote to another brand of stick (usually TCP) then it can be done. Cheers!

Fantastic content. Could you explain a little more about using the CORS Station data that you refer to? In my RTKpost app, the rover file window is just titled ‘Rinex OBS’ and the Base window is greyed out and unusable. When I put my converted .obs file in, along with the .nav file created from the RTKconvert that I got from the RTCM files, my error is very large and the points are scattered about. For reference, I located a known point with a GPS receiver, set the D-RTK station on it, changed the base coordinates to the correct ones, and flew my mission. Do I need my local CORS base data that I used via network to locate the base point? Am I missing a step in the workflow?

@prodronesasia5262 Жыл бұрын

A CORS station is a GNSS station that is Continuously Operating. It typically forms part of a service network of GNSS stations that you can connect to as a reference network in real-time or download RINEX data from for post processing. For the issue with RTKpost, check the settings tab and set it to Kinematic. Then you should put your converted data into Rover and the data from reference to Base. Hope this help. Cheers!

I've very new to this and trying to understand. If I want to use the Base station just to mark a know point, do I have to add the height of the antenna to the altitude reading? Or are the values displayed in the controller accurate as is. Thanks

@prodronesasia5262 Жыл бұрын

From testing, you have to subtract the pole height to get the position on the ground. Cheers!

@bnoll712 Жыл бұрын

Can you use the data from Tip #3 method to get good measurements on that point, let sit for 15mins, then enter those values into the base station and connect base station to aircraft for RTK flight? Or just mark GCP's with that mode 3, then switch back to mode q for the flight?

@prodronesasia5262 Жыл бұрын

That's typically what we recommend for a quick measurement of location. And since the pole height basically cancels itself out it makes thing easier to do. You just have to capture the value from the RTK settings menu by taking a snapshot with your phone. There is no automatic way to do this. Hope this helps !!! Cheers !

Excellent video. Why when I connect the antenna to an ntrip service to take points on the ground, when downloading the points from the remote control and viewing them on Google maps they appear more than 1 meter from the actual position, some kind of coordinate conversion is necessary to view them on google maps?

@prodronesasia5262 Жыл бұрын

We have seen this issue before. We suspect this is due to small offsets in the map services because when we place the points into the orthomap, they seem to align pretty well.

Hi. If you have a P4RTK remote, you can use one as a base and one as a rover for real time measurements. If via PPK then 1 or 5 shouldn't matter for both. Hope this helps

Is d-rtk2 on top of a known point? How did you input the known point coordinates onto drtk2?

@prodronesasia5262 Жыл бұрын

So we can actually measure the DRTK2 position in 2 ways. 1) We use the measurement app in the P4RTK remote to measure vs a CORS network 2) We PPK the position of the DRTK2 Then we can switch mode and key in the coordinates. Cheers!

I was reading on a DJI forum and they were saying to ADD antenna height to the Z value after it sits for 15 mins....then connect to rtk p4 drone and fly mission. But I've also seen where you Subtract the antenna height in the Z value to mark points for a GCP. I guess Im confused. If I use antenna only for corrections, let sit for 15, ADD to Z value and fly. IF just marking points for GCP, you minus the height? Any clarification would be helpful. Thanks.

@prodronesasia5262 Жыл бұрын

So the concept is like this. You have an antenna mounted on a pole. And the reading you get is for where the antenna is. So, when measuring the position of a GCP, what you really want is the position of the GCP on the ground not the antenna. So you subtract the pole height so that you virtually place the antenna on the ground to measure the GCP height. The reverse is true when you want to set a reference point. You know where the point at the tip of the pole is but what you want is the position of the antenna. So you add the pole height from the GCP position to get the antenna height. Hope this helps. Cheers :)

@bnoll712 Жыл бұрын

I have also read where if you are using the Drtk2 as a stand alone, no benchmark, no known point, just set up in an open field, and you let it sit for 15 mins and connect P4PRTK, you dont have to adjust anything in the Z value for antenna height and that the software accounts for that automatically so all you have to do is fly mission for accurate data. What are your thoughts on this? Thanks for replying to me. I'm grateful for your help in understanding this.

I have to fly under a bridge. There, the GNSS antenna obviously does not record the position of the drone. I have my D RTK 2 station in a near place where is very well connected and it is recording his correct position. It still communicate with my Matrice 300 and P1. So my question is: Will my photos be recorded with the correct positions and so their geotag ? Please someone answeeeer :)

@prodronesasia5262 7 ай бұрын

Hi, first of all, without going too much into the details of how RTK works, the answer to your question would be maybe. Why? Because the job of the DRTK2 it to provide correction data for the RTK system in the drone to correct itself. So the RTK system of the drone still needs to receive GPS signals itself to be corrected. BUT, the system can work with partial shading and can hold some positioning accuracy with the internal guidance system. It will depend on ow wide the bridge is, how high it is, how close to deck you will be and how fast you plan to fly through the under side. Hope this helps.

Mode 5 is the mode to use the base station to connect to the newer aircraft like the M300, M30, M3E and even the newer Agras models. There is no support for Mode 2 at the moment. Mode 4 is as a base for the M210 RTK V2. Hope this helps. Cheers :)

Yes you can. There are 2 ways. If you have a P4RTK remote, you can record it using RTK. Otherwise, you just need to set it on the point, turn it on and wait for the middle LED to turn green. Give it 15-20 mins then turn it off. You can then extract the data and PPK the point.

Why is there a possibility to manually give the coordinates to the remote when using the base station? Is it necessary to do that and why woul you? wouldn't the base station know it's position?

@prodronesasia5262 Жыл бұрын

A base station fundamentally only has the same accuracy as a standalone L1/L2/L5 GNSS rover. If we were to make it a base station, it would average a number of readings and use that as its current location. This means our centimeter precise drone location is only centimeter precise relative to the base but not in absolute terms like relative to a national datum. To do that, you would need a reference to accurately locate it (usually vs a CORS network or some existing network/database) and then key in the precise coordinates using the remote. Cheers!

Hi. Yes you are right if I were doing it to get a data point. I usually use kinematic to see how much the deviation data as we need it accurate and precise. So using kinematic, we can see the data spread to quickly see how good the quality of data is. Hope you get my point. Cheers!

Every time, you turn it on, it actually records all the GNSS data recorded in the internal memory as RTCM data. So all that was done was to turn it on, give i 15-20 mins then turn it off. The GNSS data was recorded and then stored. Then the DRTK2 was brought back to the office to have the data extracted and processed. So you can use the DRTK2 like a static PPK rover. Hope this helps
