Mysterious Drones Flying Nighttime Patterns Baffle Colorado Officials (thedenverchannel.com) 82

doug141 writes: At least 17 big drones, likely over the FAA limit of 55 pounds, are flying a grid search pattern over NE Colorado (Warning: source paywalled; alternative source), nightly between 7 and 10 p.m. at 40 MPH and about 300 feet. The FAA has no information and the USAF and DEA say the aircraft aren't theirs.

        If I were going to guess, I'd guess whoever it is is looking for leaks in the natural gas infrastructure: wells, collection networks, pipelines. Colorado has new tougher rules in place. Do all the testing out east where things aren't as dense before moving into the areas where wells are much more widespread.

          I've also seen speculation that they could be from the other end of the spectrum : looking for potential drilling sites. Exploration companies have been using aerial photography for decades, I would not be surprised if some are trying out automated mapping with drone swarms, and as you point out, a nice quiet rural area would be a good place to test the process.

For a long time, the market has been in satellite imagery, looking for absorption in the mid infra-red, using solar illumination (i.e., done in daylight, from invisibly high).

            There is probably still a market for aerial photography, but at the level of building access roads (for seismic, for drilling, for extraction trucks or pipelines) and for the purpose of proving the absen

But ... and this is the big "but" ... you need to either pass your light (with a spectrum that you know) through the sample, or you need a bright external source (with a known spectrum) from which you pick up backscatter. One adds considerably to the weight you need to carry (ungood for drones), the other ... flies by day.

      You make a good point. It's tricky to see anything at night during the day.

      • Except that Marijuana cultivation is legal in Colorado.

        Yes, but not all grows are legal. My understanding is that they don't spend so much effort on finding illegal grows in Colorado as here in California where they made the licensing scheme ridiculously onerous and therefore many people attempt to bypass it, but there's always someone.

    Literally.

    • Do you freak out every time you see a plane in the sky and don't know who the pilot is?

      Not knowing who is operating a drone doesn't make it a UFO.

      • Yes, actually it does. It's unidentified (they don't know EXACTLY what kind of drone or who's operaring it, it's flying, and it's an object.

        That's all a UFO is.

    • Not quite - they've been identified as drones, just not who's drones. I think a UFO is when they don't even know what they're looking at is.

      'then they are fair game for anti-drone tech to take them all down'

      No they are not. They appear to be operating legally in class G airspace. The craft aren't required to have externally visible markings. And most likely anyone that has that much money invested in multiple craft likes this has a part 107 waiver. Colorado has issued 72 of waivers https://www.auvsi.org/our-impa... [auvsi.org] . Mear operation doesn't necessarily imply that it is unauthorized.

      Shooting one down would be no different than shooting a car that passed by the street in front of your house because you didn't know the reason for operation. Or, possibly in this case because registration expired.

          You seem to have an odd idea of how the law works.

          if even the FAA & FCC and whatever government entity that is required to be notified of these drones dont know about them,

          What makes you think any notification of any agency is required? Are you required to file a report with the government every time you fly a kite or buy a helium balloon?

          then they could very well be illegal

          "They could be breaking the law." Is no excuse for shooting them down, any more than "He could have killed somebody." is an excuse for shooting a random pedestrian.

          • likely over the FAA limit of 55 pounds,

            There are regulations in that weight class. Something that big falling on someone's head is going to be significantly more dangerous than a kite or a helium balloon.

              You are correct. I deal with larger drones for my job and we can't fly them over public areas. Any testing has to be done over airfields. Oh and they all have tail numbers registered with the FAA. I never gave it much thought until lifting one. 40 pounds falling from the sky is lethal.

              • 40 pounds falling from the sky is lethal.

                From an operating altitude of 300ft (100m), a single 454g mass (I think that's a pound, but I'm not sure if American or Imperial) is sufficient to be lethal, for some shapes. Wearing a hard hat would probably shift the odds considerably in the target's favour - which is why they're required on worksites with "overhead work".

                Actually, at such low masses and long drops, air resistance (and therefore object shape and density) become significant questions.

        • Just because a drone (or airplane for that matter) is properly registered, doesn't mean you'll be able to identify it in the air. Last I checked you're not legally required to carry a transponder, nor register a flight plan, so long as you stay out of restricted airspace (commercial or military)

        The car is probably manned, the drones aren't. On the other hand, shooting at a car will get local law enforcement after you, while shooting at a drone involves the feds.

        Some drones, with which you have some familiarity, may do that. Others may do differently. Unless you can cite all the laws which apply in your country, then all the exceptions. That should take you a few days writing.

        The computational demands of terrain following and dead reckoning are pretty low these days. Even "find a flat area, land and turn on the come-hither strobe" isn't exactly hard to think through, and when your drone's weight is "on it's feet" t

    I don't see anything to indicate that the drones are operating illegally. (thought this may be an indication that rules on drone use need updating). I could imagine all sorts of remote sensing technology tests for some company that for reasonable competitive reasons doesn't want to reveal what it is doing.

    The night time operation is interesting, but could just indicate that the work is being done on the drones during normal work hours.

    Following is an incomplete list of defense contractors in Colorado. Law enforcement agencies, wildlife management [state.co.us], and fire prevention [colorado.gov] are also researching drones. If you take down a drone because you think it is operating illegally, or perhaps beause you just don't like them, you should be prepared to be the center of a shit-storm of legal action.

    Alternately, you could acquire a cheap software defined radio [bliley.com] and run something like dump1090 [satsignal.eu] (don't forget UAT on 978 mhz [stackexchange.com]) and watch very closely what is, or isn't, broadcasting it's location. Online services like Flightaware won't show low and slow little things, and will also filter out signals requested by operators for privacy reasons, so receiving the data yourself is the only way to be sure if something is broadcasting. If a drone is designed to be operated over a municipal area, then it might be broadcasting ADS-B [wikipedia.org] information that will at least tell you it's FAA registration information. If a drone is not broadcasting ADS-B info and it flies outside of class G airspace [wikipedia.org], and you can document it with good photographs and recorded ADS-B data of other, overhead aircraft (airlines are everywhere), then you've just documented a regulation violation that jeopardizes everyone's safety, especially civilian aviation. Please report it to the FAA [faa.gov] and local law enforcement with as much data as you can. But please, don't take the law into your own hands. It would be silly to face legal action because you interfered with an agency legally tasked with counting antelope.

    • The other thing I would add is trespassing on private land used for agriculture (which is almost all of the land in this area) in Colorado is a felony, especially with a firearm and it is illegal to shoot from public roads. Not to mention these drones are too high to shoot down with a shotgun and shooting a rifle into the air is absolutely stupid.

          There's nothing to come clean about, and trying to bring down such drones with fishing line or balloons will land you in a world of hurt from which you cannot hide. High-end drone sensors can see such things quite well. The chances of these drones being operated by local or federal law enforcement is quite high, and if they are being operated by a defense contractor in test and development, then they'll have both federal and local law enforcement on speed dial.
