Finally, the only daily, global, free map of GPS interference has officially launched: gpsjam.org Watch jamming around conflict zones develop over time. Wonder who's jamming GPS all around Moscow. Like all the best maps, it raises more questions than it answers!

Iran just released footage reportedly showing one of its air defense systems successfully hitting an American F-35.

@thisisharding @Aviation_Intel @carlfranzen That is precisely the mistake that gets made almost every time: It's almost impossible for people to judge how far away lights in the sky are at night. Which is why stars and planets get mistaken for drones. They _weren't_ a couple hundred feet away.

@Aviation_Intel @carlfranzen I didn’t realize how up close many of these were. Harder to believe they were mixed up with regular air traffic if the observers were only a couple hundred feet away.

What Cops Saw Chasing Down New Jersey Drones A large tranche of never-before published documents provides insights into what law enforcement saw in the skies during the drone scare of 2024. twz.com/air/what-cops-…

@Aviation_Intel It should be "what law enforcement *thought* they saw." Some of these have already been debunked, most of these sound exactly like all the other eyewitness accounts that were also debunked.

It would get more complex if you were doing a ballistic trajectory prediction, e.g. simulating a CIWS. Check out this blog post for a good solution: forrestthewoods.com/blog/solving_b…

You can use the quadratic formula to make homing missiles properly lead and hit their target. I've used this in games for like a decade. I wish they'd use examples like that in math class. Give practical/fun examples. I hated math b/c it was too abstract. Gamedev made it fun.

Neguse: Where is this company headquartered? Noem: I don’t know. Neguse: I don’t know either. We can’t find it. We did find an address that’s registered to a political operative. This company that received 143 million dollars was incorporated 8 days before this contract went out. You want the American people to believe that this is all above board, that $143 million of taxpayer money just happened to go to this one company that doesn't have a headquarters, doesn't have a website, has never done work for the federal government before and is registered apparently or attached to a residence from a political operative, and of course one of the subcontractors of that contract, as you know, is a political firm that's tied to, to you back when you were governor of South Dakota?

Here’s what happened in El Paso per multiple people briefed The Pentagon planned to use a high-energy, counter-drone laser without having properly coordinated with the FAA first about potential risks to civilian flights The Pentagon has been testing this tech for a while now in more remote areas and FAA and Pentagon officials had been scheduled to meet February 20 to review potential impacts and mitigation measures for a test of the laser system But for unclear reasons (perhaps there was a drone incursion, which happen multiple x per day) the Pentagon sought to deploy the system sooner around El Paso, prompting the FAA to impose the temporary flight restriction until proper coordination could occur. The 10-day restriction would have expired on February 21, one day after DoD and the FAA were set to meet. The FAA did not tell the WH it was closing the airspace cnn.com/2026/02/11/us/…

@lemonodor @youyoyotoo @TheMaineWonk I mean I hate to be conspiracy theorist but the reaction with no warning seems like there was a classified thing happening in that area and they didn’t want people noticing something on the ground from the air?

‼️‼️ UPDATE: In addition to El Paso, Air Space has also been shutdown around Santa Teresa, New Mexico for 10 days & New Orleans for 5 days citing National Security. Congress was NOT notified before hand and two members of Congress tell me they are learning of this in realtime.

Upon double-checking, the FAA's TFR for El Paso cited "special security reasons" without mentioning GPS jamming (per FAA site and Bloomberg). Social media posts linked it to military GPS tests at Fort Hood (~550 miles away, Feb 2-27), but no official confirmation ties them directly. The restriction was issued then lifted within hours amid backlash.

🚨🇺🇸 El Paso airport shut down for 10 days. Nobody was warned. Not even the military. FAA says it's GPS jamming exercises covering 600 miles of Texas. City council scrambling. Army scrambling. Even military flights don't know if they're grounded. Source: @thenewarea51, @AZ_Intel_, @Osinttechnical

@MarioNawfal @thenewarea51 The FAA didn't say it was for GPS jamming exercises. Those exercises are pretty routine. Here are the ones active today.

@grok @JoseUrru89 @MarioNawfal @thenewarea51 @grok Can you cite your reference for it being related to GPS jamming? There are GPS jamming exercises nearly every day in the U.S., they're relatively routine. And I haven't yet seen any reputable source say this TFR was related to GPS jamming.

Yes, multiple sources including the FAA and news outlets confirm a temporary flight restriction was issued for El Paso airport on Feb 11, 2026, initially for 10 days due to special security reasons related to military GPS jamming exercises. However, it was lifted within hours after causing disruptions and criticism for lack of notice.

My dad (Richard Feynman) had a side hustle doing industrial consulting. He'd spend a few hours visiting a company, talking to the engineers, looking at stuff, and then maybe have a good suggestion. Sometimes he would bring his son along. I only recall one of his suggestions, but it made the company he was consulting for way better off, so I guess his exorbitant consulting fees were worth it. We could have been wealthier if he had done it systematically, but he didn't want to be organized about looking for jobs, so it just happened when someone asked.

@chrisclarkefly @DJSnM That’s what they did. Networks other than ADS-B Exchange don’t show the spoofing. The aggregators have anti-spoofing measures but they’re not too hard to circumvent.

ADS-B is public and unencrypted, anyone can generate radio transmissions that will be picked up by amateur network and reported to aggregators. ATC still use traditional Mode-C/S transponders that get pinged by ground stations making position harder to spoof.
Thenewarea51@thenewarea51

ADSB shenanigans. Air Force One was spoofed as VANCE 1 and drew the JD Vance meme picture over Mar-a-Lago in Florida this evening taking roughly 2 hours to draw. The tracks are color coded by altitude and was created by having VANCE 1 fly at altitudes between 20,000 - 50,000 ft.
