He uses a 4G connection in both of these videos, but it is impressive anyway.That same YouTube Channel posted another video where he takes off deep inside what seems to be an underground garage, goes out flying in the city, descends to like 20 feet above ground somewhere far away, in between a bunch of buildings, and initiates RTH. The 3S then comes all the way back even though as soon as it enters the garage, GPS goes to 0 and it still needs to fly a few more minutes to get to the home point! Really incredible!
I would hope it gets smarter than that. If you fly for 20 minutes and you only have 5 minutes of battery left, you cannot simply retrace your steps so I hoping the improvements this new type of smart return would be able to adjust for battery strength as well as wind conditions, objects that move, and other unexpected situations. If a pilot can fly the drone home, the perfect RTH process can do it to...without a pilot.It looked a lot like it was just retracing it's steps. There was a much more efficient route to "home".
Yes indeed! My post wasn’t about the signal, just about the new RTH capabilities.He uses a 4G connection in both of these videos, but it is impressive anyway.
Honestly hard to believe even though I’m seeing it with my own eyes.
The Air 3/Air 3S has a spot on the top underneath a cover where you can install a special DJI cellular dongle and insert a SIM card inside. The drone itself connects to a cellular network. If your RC doesn’t have Wi-Fi, it needs another, separate, cellular dongle to connect to the USB-C of the RC. These are not available in the US.Very impressive.
Does it rely on having a 4G or mobile connection inside?
Is it getting the mobile data connection through the controller or it has a 4G modem on the aircraft?
What would it have done if it encountered cars or pedestrians in that tunnel?
Public garages wouldn't allow flying inside probably?
Nor flying within a city with high rise buildings potentially blocking GPS?

Anytime you see the RC single drop completely in the video, the drone is relying solely on the cellular connection for sending telemetry and video data and receiving commands from the RC.
The RC signal and the cellular 4G single each have their own separate signal bars on the top right corner.
LOL I mean I think that’s because that goes without saying in this case. It is very very very clear it is BVLOSCame for the BVLOS comments. Was disappointed...![]()
This video is causing a lot of misunderstanding. The RTH or “positioning” has nothing whatsoever to do with the 4G signal. This can be done without 4G at all.Amazing that a 4G signal is enough for stable positioning without GPS. This is a case of don’t try this at home ( unless you have access to this 4G feature).
No. Mapping is done completely in the drone. It does not need any connection to anything in order to RTH. It would work in the same exact way with only the RC2 and no 4G connection and even if the drone disconnected from the RC entirely, and had no connection to anything. It would still Smart RTH to home point.OK, so it has to be connected to some data stream, either via the controller or directly, in order to navigate, especially if it loses GPS once it enters the building?
Obviously impressive that you could get a strong signal in the garage. In some cities, I've seen subways with strong mobile network signals but it's not universal.
Really surprised that there's good 4G signal in the garage and that the radio connection between the drone and the controller was strong.
Hell, even flying in the middle of all those high rise buildings, I'm not sure there wouldn't be signal strength problems, since the aircraft will go around the corner and no longer have VLOS.
I know with my M2P, I'd at least get warnings about low signal strength and probably warn you to have the drone RTH.
But the transmission system is several generations older than O4.
Flight path recording and 3D mapping technology.So no GPS and no 4G and it would find the Home Point how?
