#122So, they spoofed GPS and jammed the rest of the communications to make it land automatically. Given that there are test transmitters for GPS devices used when consumer devices are being created it's not a surprise that they managed to do this. Not very long ago there was a GPS jamming exercise in the UK done on a military range. I realize that as a Westerner I shouldn't be rooting for the Iranians but if they did spo…
The chances of this machine relying completely on GPS for navigation is closer to none than slim. I'm not saying the article is completely wrong, just that it's probably missing a giant part of what happened.
If course it is missing a giant part of what happened. Do you think the Iranians would tell about all aspects of it to a newspaper?

Sigh.. I hope it was not that insecure.
All of the military GPS receivers also use the civilian signal to initialize their position to lock on to the military encrypted signal. I would assume that in the event that they lose the P code, that they would revert to the C/A code.
Still a horrible security design if that is the case.
Simply jamming something should not by-pass an authentication mechanism.

I am on The List for notification of these exercises, and they are happening with increasing frequency. Someone has decided that a GPS denial scenario is looking probable and is preparing accordingly.

I'd be interested to know who, other than Iranians, considers Iran the "good guys."
Alright, I don't give a fuck one way or the other. You tell me what makes them the default bad guys and what makes US the default good guy or neutral guy?
I don't think the US is perfect by any stretch of the word. I just have a hard time imagining a third party deciding that Iran is the example they'd rather move towards if given the choice.

I don't know their actual hacking mechanism, but a replay attack could be done such that valid but incorrect GPS data is sent to the drone. The gist of it is that one records signals coming from GPS satellites and retransmits them. It could be transmitted with enough power to drown out any signal from actual GPS satellites. There should be a time component in the signal that wouldn't match the internal clock, but may…
Time is literally what GPS satellites are broadcasting.
Yep:
"Radio waves are electromagnetic energy, which means they travel at the speed of light (about 186,000 miles per second, 300,000 km per second in a vacuum). The receiver can figure out how far the signal has traveled by timing how long it took the signal to arrive." -

#127(Prelude edit: A few people seem to be missing the point I'm making here. I know quite a lot about the predator, and a bit about the Global Hawk. I do not know much about the Sentinel. The jab about building a drone with parts on my kitchen table is a joke, meant to illustrate that this is either an absurd level of incompetence on the part of Lockheed Martin [not likely] or the article is incorrect, the latter being…
What becomes really really scary about this is the idea that they're relying solely on GPS to fly. GPS is pretty damn precise, especially once you add local ionosphere corrections (via WAAS or similar) and get to use the military signal. It's certainly good enough for navigating an airplane, because it's more accurate than what was in use before GPS (VOR). Edit: relevant diagram: http://en.wikipedia.org/wiki/File:Acc…
Doesn't everyone get to use the "military signal" now?
The LSB's used to be encrypted, but the codes are public now?
Re: Report: Iran Hacked, Hijacked U.S. Drone
#128Lets flip the tables here and imagine Iran is flying surveillance drones over mainland USA, gathering photos and who knows what else. Would it be unreasonable to think the USA would try with everything they've got to shoot them down and/or capture them? Who would be the bad guy in that scenario? I find it amusing nobody has thought to question what right the US have to fly a surveillance drone over Iran to spy on the…
I don't see anyone saying that what Iran did is wrong, do you? It seems that prevention is expected. The secret of international law is that it doesn't really exist. Or that the "law' in "international law" does not mean the same meaning as the "domestic law" within a country's borders. All you have are agreements between countries but with no true external body that can enforce penalties or punishments without the t…
> the "law' in "international law" does not mean the same meaning as the "domestic law" within a country's borders.
That's true. And also, the "law" in "domestic law" doesn't apply equally as people assume it does. Really, it's a huge fairy tale that "everyone is equivalent in the face of the [domestic] law", which for some reason many grown ups believe.
It's really a sad choice of words that the word "law" is used for both physical phenomena, where it i absolutely applied, and legal situations, where it applies mostly when it isn't inconvenient to the rulers (which is a word that better described what's usually called "leaders")

I believe what happened was that some hackers went to known locations on the planet, listened to the signal, then used these pairings to reverse engineer it.
Eventually it was simply declassified.

#130I've seen a lot of these drone stories and discussion threads. The most interesting thing about them is the assumption that America has the right to violate other countries territory.
