Drone sniping

At least where I live, little Billy would have to be about 1/4 mile from his house (closest neighbors) to fly it over my property, the last thing it would record is a muzzle flash from my 12 gauge. Let him and his dad come down to ask me if I had seen it !

I'm suspicious of that lemon farmer video. That guy on the hill behind the house looks awfully far away to be controlling a drone at the front of the house. My DJI would come back to me if I sent it that far away, and that copter looks a lot like a DJI. Anyone in their right mind would get the hell out of Dodge as soon as that guy came out with a shotgun, not hover there in front of him.

The technologies associated with UAS (they are not "drones", which are targets: History Tuesday: The Origin of the term Drone | Intercepts | Defense News) are leaping ahead faster than Moore's Law.

A friend of mine and soon to be partner in UAS demonstrated an 11 miles plus range with a small quad rotor last week to Office of Naval Research.

I've heard of RC planes being controlled by short wave. I just don't think the guy in the video could do what he was purported to have done with an out of the box copter.

This one was certainly a target!

BTW I think the term "drone" is going to go the way of "nucular" vs "nuclear." I used to cringe when I heard Jimmy Carter and GW Bush say "nucular." But it seems widely accepted now. I still cringe.

I find it all rather humorous but can't see how anyone could defend the drone user flying over someone else property. That airspace ruling is nonsense. Things do go wrong and maybe the private neighbor has other concerns.

What if something goes bad, potential crash landings, POS dropping out of the sky onto someone, take an eye out, whatever?

It's one thing to have little Jimmy flying his RC vehicle and going over your house and another to have one with a camera distinctly watching your property. Little Jimmy I would dismiss the same as I would a car driving by but to sit there with a camera over the property would be the last flight it took.

My nearest neighbor is 1/4 mile away and I doubt they would be flying it over our property so I don't really give it a thought.

This is very cool.

Ft. Carson Says Downed Drone Found in Man's Yard Lost Communication With GPS

[wdfifteen]

"The Gazette say when it was found in that neighborhood about 11 miles away, that's nearly double the drone's projected range of just over 6 miles."

A six mile range for a little thing like that. Seems like it could easily run out of propulsion power just getting out that far and back.

The range is 10 kilometers for control of the aircraft, line of sight. The endurance of the vehicle is 60 to 90 minutes. It can fly many more linear miles than 6.

You can find the spec sheet here: Raven UAS (UAV) - AeroVironment, Inc.

I bought a whole bunch of these things for the USMC when I was in uniform. The battery technology advances (much more to come) have greatly increased endurance.

The Department of Interior and other government agencies are using the old A Model Ravens.

Here is what you're looking for a quad rotor with a full auto M16 mounted underneath
This dude is cool.

meh. My expectation...

People are going to take out drones about as much (or less) as people take out red-light cameras. ...which is to say they're not.

Electromagnetic pulse
From Wikipedia, the free encyclopedia

An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse may occur in the form of a radiated, electric or magnetic field or conducted electrical current depending on the source, and may be natural or man-made. The term "electromagnetic pulse" is commonly abbreviated to the initialism EMP (which is pronounced by saying the letters separately, "E-M-P").

EMP interference is generally disruptive or damaging to electronic equipment, and at higher energy levels a powerful EMP event such as a lightning strike can damage physical objects such as buildings and aircraft structures. The management of EMP effects is an important branch of electromagnetic compatibility (EMC) engineering.

The damaging effects of high-energy EMP have been used to create EMP weapons. These are typically divided into nuclear and non-nuclear devices. Such weapons, both real and fictional, are becoming known to the public by means of popular culture.

I guess there is now a market for Barrage Balloons.

Funny.

There really is no visual privacy in the macro. Let us not forget the manned aerial surveillance/photo folks take amazingly detailed photos as well. When I leave my farm I have no expectation of visual privacy. None.

That aside, the real in your face UAS will not be the quads: Small, fixed wing UAS that fly at 400ft agl (you cannot see or hear them) on reprogrammed flight regimes without operator intervention are what I use for most commercial applications.

They are for all intents and purposes, invisible.

Boo.

OK, we'll go paint ball then.
Some of them paint-ball spoons can rapid fire. Legally.
Even if it doesn't bring it down it will blind it with paint within a few seconds, and make a royal mess of it.

Member that cheech and chong movie where they camoflaged their growing facility so it would look like a swimming pool from the air?

EMP or ElectroMagnetic Pulse Transformer (EMPTy) bombs are not directed, not a great choice unless you want your house to go dark or you live in a yurt. Usually those are deployed in the air to quiet the neighborhood below.

High Energy Radio Frequency (HERF) or Tesla guns can be ground based and as a directed energy weapon they can be a lot less powerful and be very effective, especially against a commercial drone. They don't disrupt communications between the drone and controller like others have discussed but instead create voltage spikes and sparks that can disable the electronics on the drone itself. think fry the camera, fry the communications, fry the controller circuitry all at once.

Most stuff is shielded nowadays to prevent even small spikes but I doubt they are putting any of it in cheap drones. And even if they did, it's counterproductive to shield communications back to the controller so there will always be an achilles heel.
