Actually, DJI's anti-drone tech is NOT news and has been covered ad nausem. I was advised that investing in companies on the stock market: developing anti drone tech is a bigger growth opportunity than those making drones. That said, DJI is very clever and recognizing their own strengths. And yes, cashing in on both sides of the coin. While their customer support has vastly improved from several years go, there is still a disconnect between the various customer service agents , the DJI "senior engineers" and accessibility as well as information flow among the hidden other entities. My Inspire should get frequent fly miles for the number of trips I've had to re-send it back because the repair people go by a script and do not read enclosed documentation of issues. That is changing but instead of building a huge ego twin tower in schenzen, they should provide an east coast service center with well versed technical folks who actually fly drones and can think outside the box. It may come....if nothing else but to service the anti-drone technology and treat drone pilots as an adjunct. LOLI wasn't aware until today that DJI was making Drone Detection systems for the FBI and others to track drones. My Mavic 3 was detected and id'd by the FBI using Aerial Armor and Aerial Armor's main detection system is DJI Aeroscope. DJI Aeroscope | Premier DJI Drone Detection Technology | Aerial Armor
Kind of like the guy who invented radar inventing the radar detector and cashing in on both sides of the coin. They knew everything, where I was standing, where I flew, how I flew who I was etc... Without disclosing pertinent information, I was not in any trouble nor did anything wrong, however as someone who frequents these forums I had no idea that this ability of tracking was already in play.
I don't know how "enforced" federal agencies are prohibited from buying DJI...tho the drone companies now operating with the vaunted "BLUE LIST" are marketing their non Chinese manufacturing. I suspect the Bureau of Land Management, surveying wild horses and burros don't give a horses *** about which drones they buy. I have seen videos of their using Phantoms.....The feds have it in for Chinese companies. There was a chance they'd ban DJI projects like they've banned Huawei equipment.
I don't believe federal agencies are allowed to buy DJI drones for official use.
The thing is, all these sensitive installations like military bases and such can all be seen in satellite images. We probably have those satellites and so do the Chinese.
How did they know where the OP was operating the drone from then?Neither Remote ID nor Aeroscope have anything to do with any internet connection, nor a connected phone. All the information they require is coming from the drone itself. Detection of a radio signal broadcast from the drone also has nothing to do with radar. However, Aerial Armor also uses radar, according to their website, cited in post #4 above.
The remote pilot GPS location is being transmitted continuously just like the drones GPS location. Also the home point is being transmitted as well.How did they know where the OP was operating the drone from then?
It must be able to detect the controller in some way. Is it emitting that much RF?
You are. I had forgotten that you were testing Night Mode over Philadelphia, which was only available after .0900, so you definitely were broadcasting RID, which no doubt assisted them in tracking all your flights, in addition to Aeroscope. RID is not mandatory for pilots until September this year, but DJI has proactively started broadcasting it from all Mavic 3's that have installed .0900 or later FW, as well as all Mini 3 Pros that have updated, despite the fact that the Mini 3 Pro is permanently exempt from all RID requirements when used recreationally with the original battery.Have no idea? I have the latest firmware, how do I know if I'm broadcasting RID?
I am still learning about drone flying but TFRs for aviation are always put up whenever there are large gatherings. I believe that their ceiling is 3000'. There was a VIP at the last Eagles game and I would not be surprised if that resulted in higher security measures. I don't believe that all the laws in the country could stop an evil doer and I have thought about what one could do to a stadium full of fans, with a drone.What exactly is the rationale for putting an exclusion zone around sporting events?
Is it terrorism concern?
Or sports teams just have that political clout and they didn't want swarms of drones getting unauthorized pics and videos of games?
Interesting that they get law enforcement to deploy so many resources to enforce it.
The Aeroscope can be more than twice as far as DJI's specs. I have seen a detection system using RF signals detect drones from several tens of miles away; if you think about it the drone is transmitting it's location probably hundreds of time a second. A detector only has to received and decode one or two of those signals to get a good track data for the drone. So they can cover a fairly wide geographical area.I am not a conspiracy theorist (tin foil hat guy) but I don't doubt the OP one bit. What I would like to know is the coverage area for this 'service'. And as far as RADAR goes, based on my private pilot experience, that is very limited but I am open to a wising up if I am wrong.
