As a private pilot, this is the kind of thing that makes me scared to fly without being well versed on radio nav aids. I feel like i know them well, but honestly i use them so rarely in practice it would likely be an uncomfortable situation.
- edraferi 9y agoWhich is exactly why the military is knocking out GPS Afro the exercise. Gotta train for the worst.
- lutorm 9y agoYeah, it makes you wonder about NextGen and the retirement of radio navaids.
- danaliv 9y agoUse them on trips when you don’t need them so you’re prepared. I flew home over New Years via VORs and pilotage just to keep it sharp.
- sliken 9y agoMost GPSs these days support GLONASS as well, my previous generation pixel phone does. Not that one shouldn't have a backup plan in case of a disruption of both.
- nraynaud 9y agoMy understanding is that it might be the gps system sending fake data, not being shut down or completely scrambled. So you might not know you are wrong.
- rdtsc 9y agoThough if you get GLONASS and Galileo you could compare and see if one is all of the sudden off? Of course if they are faking GPS, they'll probably get the capability to fake the others.
- dmurray 9y agoNormally by "jamming" they mean broadcasting noise that downs out the GPS signal. It's a lot more technically difficult to "spoof" the signal and would require transmitters throughout the region, or control of the satellites themselves. Of course the US military has both of those things, but I'd still expect jamming rather than spoofing.
- fisian 9y agoWould jamming GPS also render GLONASS or Galileo unusable?
- PeterisP 9y agoThey're similar but separate. You could jam just GPS, or you could jam all three and still call it in common speech as "jamming GPS".
- developer2 9y agoThere's no chance the U.S. military doesn't have the ability to selectively knock GPS out nation-wide. Odds are the American government has infrastructure in place to do the same in dozens of countries worldwide. GPS would never have been made available to the consumer market without this level of absolute control having been put into place. It's frightening to see how casually the American government takes disrupting GPS. The fact is, there is risk in performing these tests near civilian populations. It takes one pilot - or someone else who depends heavily on GPS - to make a fatal mistake. It's not physically necessary to black out GPS for training... just take away the trainees' hardware, or program the firmware/software to act in the desired way. "How do we train our troops not to rely on GPS? I guess the only way is to disrupt GPS for a thousand miles around the training site!"
- phil21 9y agoI think these tests should happen military excersizes or not. In fact turn the entire constellation off for 24 hours at random periods once every few years or so. The over reliance on the GPS system is downright scary, and I doubt we even have a real idea of where the second-order effects lie. What happens when all the CDMA towers lose clock sync? Are airmen still able to actually navigate? Etc. etc. Civilian preparedness needs to be part of national security "training" as well - and GPS is one of the largest vulnerabilities we have as a nation no one talks about.
- chrisper 9y agoAs a private pilot you would look at NOTAMs before flying, no?
