Mostly they’re used to enable illegal RF parameters in Europe (FCC hack); DJI disabled strict geofencing in most of the “west” several years ago and that was also enforced in the drone anyway.

Root for these RCs has been available under the guise of “FCC hack” for a really long time now; different groups have different exploits (it’s DJI so there are plenty) that work on different firmware versions. This would almost surely work

Western state agencies and mid-tier bootleg spyware vendors are neutral at best and antagonists overall. At best, bootleg spyware vendors drop exploits which agencies can reverse and use for their own purposes. But in general, these vendors

These generally just use RTK and a base station; nothing interesting and extremely easily rejected by EW (since they need both accurate global positioning signal _and_ RTK signal). Inside-out SLAM strategies and on-device ML are much more i

Walksnail is not 802.11 based. If anything it is loosely 802.16 based. Likewise DJI OcuSync is more like LTE than anything else. 802.11 is not a good fit for FPV video and trying to use it has held non-proprietary-Chinese video systems back

Overall what I'd say about DJI is that they seem to be earnestly trying to make their features work at face value. That is, if you opt out of data collection, they seem to be earnestly _trying_ to disable data collection. Unfortunately

No; this functionality is actually accomplished in a reasonable way, with a local database stored on the drone and checked by the drone's flight control software, and exemptions granted by uploading a signed payload to the drone detail

There's nothing. Skydio exited the consumer market. Their drones had good autonomy and flight characteristics. However, they struggled with wireless link quality due to the use of consumer WiFi, and had much older, inferior camera sens

DJI's no-fly zone database is completely independent from the US government. DJI would have to be compelled to add the US as a no-fly zone, which, if their drones are banned already, seems like a rather difficult thing to compel as the

Sure, but DJI drones already weren't eligible for procurement in US defense anyway, so there's not a major net change there (barring weird edge case loopholes with third-party modifications). Skydio already got their protectionism

DJI OcuSync is based on LTE: https://www.suasnews.com/2022/05/the-dji-p1-and-s1-fpv-chips... is an example of more information. This is a major advantage DJI and other Chinese drone makers have over US based ones.
