DIY Drones

There's a provocative piece in the current issue of the AUVSI's offical magazine, Umanned Systems. It asks how likely it it is that terrorists will use UAVs, which is as you might imagine is a question that comes up quite often for those of us in the open source UAV world, where we don't restrict who uses our technology.

The article notes that UAVs are not the best choice for terrorists delivering explosives, given their complexity and relatively low carrying capacity, but does raise the issue of UAV-distributed chemical and biological weapons. It quotes Vann Van Diepen, then the Department of Defense's acting deputy secretary for nonproliferation, warning in 2002 that UAVs "are a potential delivery system for weapons of mass destruction and indeed and ideally suited for the delivery of chemical and biological weapons, given UAV's ability to disseminate aerosols in the right place at the right altitudes."

But others quoted in the article are less concerned. Wayne Morse, president of American Dynamic Flight Systems, a UAV maker, said it's unlikely that terrorists would choose UAVs. "It doesn't make sense. UAVs are very complex and terrorists want to terrorise. How can you best do that that? If you have people willing to kill themselves, that's what terrorizes. So why aim UAVS at the Super Bowl when you can have somebody walk up and self-detonate before they go through stadium security and cause mass panic?"

Renting a Cessna would allow a terrorist to carry a much larger load, much more simply, Morse said.

The article is available as a pdf to AUVSI members. BTW, joining AUVSI costs just $50 a year for individuals, and comes with a free Unmanned Systems subscription. Highly recommended!

Interesting article, but I tend to agree with wayne morse, in terms of destructive purposes, but what about if terrorists used them for basic aerial surveillance?

If up against a regular army, I assume it might have worked the first time used. The second time I would suspect one of two things to happen:
1. UAV brought down, by bullets, electronic warfare, lasers or other means,
2. Terrorist blown away when picking up UAV

War on Terror = Hoax

There is evidence that contradicts the premise of this notion.

Patrick, what notion?

When people can fly airliners into buildings without hindrance - I dont think an amateur UAV is a major threat...

IMHO, Why add fuel to fire now? Have enough hinderance and opposition from faa , aaf, abcd and who knows who else, but we all know the available tech in public forum is still far from presision targeting solution required for Mr. T's intentions, futher more other simple and almost zero failure tech is availble to them which we see/hear every now and then. So pls, lets move on, however keeping periferal vision open.

The "notion" is that this tech is beyond the scope of adversarial interest. This is the old fuel that started the fire. The technology is low hanging fruit when viewed as a threat and exacerbated by the lack of a powerful lobby.

High powered rockets are a better delivery vehicle to something like the Superbowl where the target is enormous. Just getting over the wall into an open-air stadium & landing anywhere is effective. It's easier than UN sugar motor Qassams from Gaza, most of which hit nothing. The Prototype This TV show built autonomous life ring delivery systems that react to a GPS-tagged distress call from a beach swimmer's armband. They had a *much* easier time with a compressed air mortar that used the location and wind sensors to adjust azimuth & elevation than they did with a fixed wing UAV.

Let me suggest another target for terrorist UAVs: other UAVs. There are more threats than jihadis. For instance, Mexican drug cartels have killed more Americans than were killed by the 9/11 Pentagon attack and more people than all 3 9/11 planes. UAVs for interdicting smugglers isn't a big deal yet, but it's poised to become significant. Jamming might be an easier than shooting down, but autonomy beats that.

My first take on an anti-UAV UAV that's capable of targeting electric MAVs that don't have the heat signature of a Predator would be an electric glider that could fly high to watch for targets, then swoop down unpowered and use sound for targeting. Analysis would be needed to find a motor's drone in a sea of wind noise. UAVs aren't armored to save weight. If they need to survive a mid-air collision (don't even need explosive), they'll become less attractive to border county sheriffs' departments.

I'd ask that the usual rules of DIY Drones apply in this discussion: no politics (let's refrain from talking about "Republican" views), no nationalism (or antinationalism) and no personal attacks. This is a sensitive topic, which is all the more reason to stress the need for a constructive and respectful discourse.

80+ lines of text above could be= 150+ line of AP/IMU code
and surely Jordi & other coders/debuggers would appreciate such help , wish I could help with some coding. :)
BTW I was impressed with one of OSD recently. downloaded and tried to read the spanglish manual , felt so sorry that some day soon , I will try to translate it to some thing better that ppl like me can make some sense out of the manual. No Pun or disrespect intended but I am sure our energy & time could be better spent than debating on non AP hardware/software related R & D .
