These receivers mostly don’t have gps and it’s very common for people to put in the wrong coordinates.

A transponder in a car is not an "aircraft station" (§ 87.5), therefore it is not covered by aircraft "license-by-rule" (§ 87.18(b)), so transmitting would be operating without a valid authorization (§ 1.903(a)). https:

Imagine your boss doesn’t like you looking at ADS-B sites because it’s not data from an FAA approved system but as long as you’re discreet and not actually breaking a reg they don’t yell at you. Then they come in and see that you installed

Just because I don't often get a chance to talk about this, I'll mention that there was a malfunction/accident/bug that caused what you might call spoofed signals to go out around Long Island and New York. Really interes

There are non-radar towers that don't have scopes. They may have a traffic display, or maybe not. They might choose to use a public ADS-B aggregator site because it gives them situational awareness, but they don't use it to provid

That's not true. And if you click almost anywhere else on the spoofed track it will show as Source: ADS-B.

Maybe not "rely" on, but some definitely use public ADS-B aggregator sites.

(Of course if you were spoofing ADS-B RF signals you wouldn't necessarily need to be anywhere near the spoofed locations. Just like with GPS spoofing.)

As other commenters noted, this is almost certainly not RF spoofing, just sending bad data to an aggregator (ADS-B Exchange) over the internet. This instance of spoofing is notable for being the first that I know of that wasn't primiti

This is a fun project that combines a cheap PTZ camera + OpenCV, Kalman filtering, PID control, and digital stabilization to not just snap photos of aircraft flying past, but do rock solid, pixel-level tracking as long as they're in si

They do seem to be jamming GPS around Tehran at least, as seen on GPSJAM. https://bsky.app/profile/lemonodor.bsky.social/post/3mcak43p...

If they were doing that, that would be a criminal conspiracy, not terrorism. Authoritarians often like to call ordinary criminals, political opponents, and dissenters terrorists to delegitimize them and justify harsher behavior against them

The CEO of Flock, Garrett Langley, called Deflock a terrorist group. It's unhinged. https://www.youtube.com/watch?v=l-kZGrDz7PU

They're not usually doing surveillance on people, they're mostly used as a quick way to get eyes overhead when something else is happening--foot pursuit, high speed pursuit, just about anything really where an aerial perspective m

In today's NTSB briefing they said as far as they know the aircraft was not delayed and there was not maintenance work done immediately before the flight. https://www.youtube.com/live/Rw6CtQJckzE?si=9Q98BLIVDJbfZ1Q

It seems like the article has been updated: "Sources told AVweb Sunday that the focus of the investigation is on a weather balloon payload." This is far more likely than a meteor.

Back when this first launched, I said it was like writing webgl shaders for ADS-B with SQL. And I made a custom GPT that could translate natural language queries to Clickhouse's query language: https://chatgpt.com/g&#x2

It's good to be careful. A popular ADS-B network used to distribute a raspberry pi image that let the maintainers ssh into your machine whenever they wanted.

Same here. I knew BASIC very well and had done some 6502 assembly, but the COMAL disk I picked up somewhere for the C64 was my first exposure to structured programming, and it definitely expanded my young mind.

I talked to a woman who worked for the Los Angeles Dept. of Water and Power (LADWP) at a party once and she told me about some of the things they find in the sewers. The ones I remember are tampons, a dead horse, and money.

In the 90s I created a site with XSLT that rendered to HTML. I was tempted by its promises, but in practice I found it hard to use, hard to debug, complicated and extremely verbose. I was glad when I gave it up.

I have pleasant memories of using SpeedScript on my C64 to write several papers in high school. What an amazing piece of software: a word processor in 5 KB.
