GPS interference crashes survey drones in the UK. Will the debate resonate in the US? | Instant News

An expensive drone crashed into a house in December when it lost its GPS signal due to interference, according to one accident investigation by the British.

Drone, DJI M600 Pro was surveying the construction site when the accident occurred. The DHI M600 Pro can weigh as much as 34lbs (15.5kg) and is listed at a price of $ 5,699 on the vendor’s website.

The accident has provided additional impetus for those in the United States who oppose the decision of the Federal Communications Commission (FCC) to allow Ligado Networks to transmit on frequencies close to GPS frequencies. US government tests show that high-precision GPS receivers, such as those used in some survey drones, may not have a reliable signal every time they are within 3,400 meters (2+ miles) of a Ligado transmitter. Drones with inappropriate general-purpose GPS receivers can be affected within a distance of 1,040 meters (0.6 miles).

Unreliable GPS drones can roam unauthorized areas and end up stuck. The bigger and heavier the drone, the more dangerous it is. Most commercial drones weigh less than 100 lbs (45kg), although some models can weigh 200 lbs (90 kg) or more.

While drones should remain in the operator’s line of sight, when GPS navigation is lost, many enter “attitude mode.” This results in the aircraft maintaining its altitude above the ground and its wing level using barometric and inertia sensors. It cannot hold its position above the ground, without GPS and will be washed away by the wind. Unless the operator takes manual control immediately, the drone can drift out of the operator’s view. That usually also means it cannot receive radio commands sent by the operator.

This is what happened in this case, according to British Aircraft Accident Investigation Agency Report.

A survey of construction sites by drones was on the second day. The first three flights without incident. On the fourth flight, the drone took off and reached about 65 feet above the ground. The pilot controller then shows the GPS compass error. At that moment, the drone stopped climbing and began to blow in the wind about 15 miles per hour. The pilot repeatedly selected the “return” function without success before the plane flew over the tree line and was not seen. It crashed into the roof of a house a few hundred meters behind the trees and fell in the backyard.

After informing the police about the missing drone, the pilot prepares another drone to look for the missing one. However, shortly after takeoff, the controller again showed an error message and the pilot immediately landed it.

Analysis of the accident report cites signal interference with GPS as a cause for the malfunction of the fallen drone and the second is to look for it. It said the source of the interference was not identified.

The report also observed that serious injury or death could occur.

… analysis shows that a mass of more than 2 kg falling from the roof of a house can result in serious or even fatal injuries to people if they are hit. The aircraft’s mass, 12.8 kg, far exceeds this figure and it is therefore very likely that serious injury will occur even if the person hit is wearing a hard hat for protection.

Interest in aviation in the United States for years has opposed the FCC giving the Ligado Networks application. Despite this and official and strong opposition from the executive branch of government, the FCC approved Ligado’s request in April.

Speaking of this accident, Brian Haynes, head of corporate strategy at the commercial drone company Airo Drone LLC, voiced concerns that seemed to represent the industry as a whole.

“As a commercial drone operator, this is a clear example of why the FCC’s decision regarding Ligado Networks must be reconsidered. We expect this type of accident, and incidents to interfere with other services, to increase dramatically with Ligado interruptions – with potentially dangerous consequences. An upgraded receiver will be expensive, if even feasible in size / weight of the drone requirements; who will take the bill, if and when repairs are available? “

FCC approval of the Ligado Network application has not silenced the opposition. But has caused opposition to spread in many industries and sectors. Vocal opponents now include agricultural, maritime, vehicle and industrial interests.

Legislation is being considered in Congress that will cause the FCC’s decision to be reexamined and prevent the Department of Defense from doing business with any company that interferes with GPS signals. Some proposals will delay FCC approval.

Senator Jim Inhofe, R-Okla., Has promised to introduce a law that will continue to get FCC approval until Ligado modifies or replaces all equipment throughout the country so that operations will have an impact.

While the drone crash in the UK can be seen as a relatively minor event, as a sign of things to come, it is likely to have a large impact in the United States.

AI Super Smart Autonomous | Instant News

It might force me to communicate with nature unexpectedly, but I still want a new drone. DJI: The Mavic Air 2.

I am a video producer, looking beyond camera equipment is my starting line. But it wasn’t the compact design of the Mavic Air 2 that allowed me to put the body in a crossbody bag, or it was a slightly larger 1/2-inch Bayer Quad sensor that made me fall in love. Nor is it due to the slightly longer flight time, which is about 34 minutes, giving or receiving wind conditions, and which flight mode you choose.

That’s because of the autonomous AI.

DJI updated the autonomous AI feature set for Air 2. But what caught my attention was ActiveTrack 3.0 and Advanced Pilot Assist System 3.0 (in short APAS). Both of these features are designed to make tracking subjects very easy – no need to fly fancy. ActiveTrack locks onto a particular subject, which in the previous version loses its target if it moves behind an object, and APAS maps the drone environment to avoid obstacles in its flight path, which is said to be better than its predecessor.

I have spent some time with drones to see how good those features are, and all of you, these two features combine to make an autonomous drone that is pretty sweet. I’m a little conflicted. AI of course increases flying but also this is how we get it Terminator. But when I put Air 2 to work, cycling through Downtown Oakland while following me, it was easy to forget the potential of killing future bots chasing me in the apocalyptic desert and was only impressed by Air 2’s ability to avoid objects in complex environments. It handles the curves and turns of the city well. I also speed up a long way to see if this bad boy can keep up while avoiding some rather than complex obstacles.

But … I did have a few hiccups during the test. Ie Mavic Air 2 is not as smart as I thought; stuck in a tree during one of my trips. When I see Air 2 flying right into a tree – you can monitor the flight cam on your smartphone – I have to switch to the map on the DJI application and use the ping location to track it. Unfortunately, the ping is not very accurate; it’s similar to Google Map. So I still have to do some detective work to narrow down the number of trees where the tree is trapped. After I thought I found the tree where Water 2 was stuck, I had to leave all the rest of my equipment, including me. stupid expensive bikes, on the ground and climbing trees for 20 minutes. Bless it is the true tree. That can take longer.

This can happen to anyone – and I can bet the cash you have in the history of flying drones. But Air 2, which does not pay attention to objects that come face to face, occurs on several occasions in certain modes. I can tell you more, but this is very cinematic and I worked very hard on the video above, so look at this and also some sweet drone shots from me that are over my fixie, bruh.

Even with this accident, I still want Mavic Air 2, especially when I’m out on the field as a video producer. Having this in my repertoire would be a blessing if I was doing solo shoot, which is increasingly common now. If you’re not in the business of making videos it’s a little more difficult to justify the $ 800 price tag of Mavic Air 2 when the adorable and more affordable $ 400 Mavic is there. But if you are looking for cinematic shots and don’t have time to learn how to fly Mavic Air 2 smart enough to make it valuable.

DJI Mavic Air 2: The value of their best drones | Instant News

The new DJI Mavic Air 2 drone won warm reviews for good reason. It was incredible.

Not only does it capture beautiful, stable, very detailed videos and super sharp 48 megapixel images, but it is also very easy to fly.

With a new propeller, it is much quieter than any other drone we’ve ever flown, so you can barely hear it so little above you.

Now offers a 34 minute flight time – much better at the 21 minutes promised to Mavic Air. Importantly, it also has a larger ½ inch camera sensor which is a very noticeable improvement.

I took my photographer partner on one of our test flights and he did not believe the quality of video streaming over my phone.

Mavic Air 2-fold offers many of DJI’s larger drone features but in something that can be easily inserted into a small camera case or backpack. Weighing just over 500 grams so it’s easy to carry throughout the day.

At the front of the video, it offers 4K at 60 frames per second and 120 fps.

You can also record HDR video, 4K slow motion video in 1080p at 120 fps or 8x slow motion at 240fps.

On the photo side, you have the option of 12 megapixels or 48 megapixels for an 8000 x 6,000 pixel image that is about 20 megabytes in size. Even in reasonable winds, the three-axis gimbal manages to keep the camera steady.

The technology around taking pictures and videos is also getting smarter with the new SmartPhoto feature to better analyze what you take.

COMPACT: Mavic Air 2 is folded to a decent size but small enough to carry all day.

In the HDR photo option, Mavic Air 2 captures seven different images from the same scene, at various exposures, to increase dynamic range, which means more detail.

We test it in the middle of the day, when it is cloudy and at sunset, and the results are consistently good.
In low light, the Hyperlight mode takes several photos and combines them to produce a decent image with less noise than you expect.

Mavic Air 2 recognizes five categories of scenery including sunset, blue sky, grass, snow, and trees, then optimizes settings. To fly, it has a new motorbike, a new electronic speed controller (ESC), improved battery technology and an aerodynamic design.

Incredibly, the OcuSync 2.0 transmission technology has been upgraded to provide stable HD video feeds from drones at a maximum distance of 10 km. Of course, that is much further than the Australian rule that says you should be able to see your drone.

One big danger with drones, of course, is crashing into obstacles, like trees or tree branches.

Air 2 has new safety features including obstacle sensors on the front and rear of the drone.

We tested them against fences and people and they worked very well in stopping the drones from moving further.

Additional sensors and additional lights at the bottom of the Mavic Air 2 help landings even in difficult lighting.

It also has a geofencing solution to help keep drones away from high-risk locations, such as busy airports.

Advanced Pilot Assistance System (APAS) 3.0 goes further to provide autonomous flights. When an obstacle comes to the drone’s path, it will create a new path around, below or above the object to avoid a collision.

Mavic Air 2 features an advanced tracking system that offers three different modes.

  • ActiveTrack 3 allows you to choose a subject that your drone will automatically follow, including the ability to re-engage the subject quickly if it moves temporarily behind an object.

  • Point of Interest 3.0 allows you to set automatic flight paths around certain subjects.

  • Spotlight 2.0 locks the subject in a frame while the user has a free operation from drone movement.

Mavic Air 2 has an 8K hyperlapse feature where you can choose an area for a series of time-lapse photos to be taken, even when our drones are moving.

You can choose Free movement, Circle, CourseLock, and WayPoints.

One of the best features of the DJI drone is QuickShots, which allows amateurs to create supersmooth cinematic videos. Pilots can choose Rocket, Circle, Dronie, Helix, Boomerang or Asteroid.

If you are completely new to drones, DJI offers a new tutorial that shows everything from the basics of its settings to more advanced flights.

The DJI Fly application offers several great quick editing features so you can make fast videos with music, text and transitions directly on your mobile.

Mavic Air 2 is available in two choices: a standard package that includes Mavic Air 2 aircraft, one battery, remote control and all cables and cables needed for AUD $ 1,499.

The Fly More Combo, which includes all items from the standard version as well as a shoulder bag, ND filter, charging center, and two additional batteries, sells for $ 1899.

This will definitely be my Christmas 2020 wish list now.
