One interesting alternative would be the Visual Positioning System (VPS) that Niantic has built from Pokemon go player data. Basically you can take a picture outside and your phone will know exactly where you are:

Too bad they’re getting close to being bought out by a company that’s notorious for squeezing out every penny from their player base.
Would this work in a war zone if everything that used to be there was gone now?
I doubt it would work well, but with enough training data it would be able to pick up on some areas. Especially if there are large landmarks in the frame (mountains/hills/rivers, etc.).
It’s also what Google Maps live view is using. Street view imagery plus rough location plus on-phone camera sensor calibration data allows it to compute highly accurate positions relative to surroundings.
Yeah so good luck using that in the middle of the woods
Understood! Anyway, thanks to the ruzzian GPS, I made a left over the canyon. Currently dangling. I think its wrong!..oh wait, it’s because I didn’t tell it to not fly or avoid bodies of water. Got it!
The article is pretty vague, but I bet stellar navigation is a strong contender. Although, it works best only when there’s good visibility of the night sky
Wait til you hear about radio astronomy:
The brightest discrete radio source is the Sun (Figure 1.10), but the Sun is much less dominant than it is in visible light. The radio sky is dark even when the Sun is up because atmospheric molecules and dust particles don’t scatter radio waves whose wavelengths are much larger than these particles. Most radio observations can be made day or night. Clouds are also nearly transparent at wavelengths λ>2λ>2 cm, so long-wavelength radio observations can be made even when the sky is overcast.
They’re called maps. I have several in my glove box.
How many gloves are in there?
Used to be 6, now 4.

I’m kind of surprised that Musk hasn’t proposed turning Selective Availability back on.
This is going to kill people in order to enrich SwastiKet.
Most receivers already use GPS, GLONASS, Galileo and beidou.
Also QZSS, but that’s just GPS not run by US (it uses GPS signalling, but it’s designed to look directly down when over a small arc of Japan (which covers Tokyo) so you can get more accurate GPS inside the ‘urban valley’
We get slightly better GPS in Australia (esp. Adelaide) due to it too, since the other end of the orbit is over AU.
We see it over the pole here in Sweden too!
as opposed to what? can’t exactly say we should use something else if the government is intent on firing everyone that isn’t actively engaging in the tariff war
Maps still work without GPS though. I wonder how many people could find their location on one?
A good 5 years ago or so I was getting a breakfast burrito when an older couple came in asking for directions. They had an old school mapbook. It took a minute to orient myself, but I found they were on the wrong page.
Its one of my bucket list items, but an old school road trip with nothing but a mapbook and a compass. No real destination, no time frame. Just the open road and exploring. And no GPS to make it efficient or optimized where I’ll soar right past everything.
Don’t really need a compass for a road trip given you are just following roads. I went on a bike ride somewhat recently following a similar idea, using a tablet instead of a book but I just had an offline map and it doesn’t support GPS. I followed various paths and roads going around. Was a nice day trip.
And this is why the EU should have ignored the US when they whined that our Gallileo system used different frequencies from GPS.
As it stands now Gallileo was built to using frequencies that the US can jam using GPS.
there’s a significant difference in jamming capability between different frequencies? Are you jamming them from space or something?
That doesn’t really seem like a significant technical limitation to me.
Ooh i did not know about that, interesting. However they could just have built their GPS sats in such a way that allows a wide range of frequency jamming anyways.
Corruption?
My phone uses the Graft Positioning System to tell me where I can go and who I can talk to.

he should explore seppuku with musk
GPS? You mean the technology that we as a country collective maintain? And have continued to maintain since it’s immediate inception?
Yeah, ok.
Call me when you start using glonass.
🤣
Who’s “We”? The Government?
“Government is too reliant on Government?” (GPS is run by the US Government)
So they want to rely less on government, but relying on a corporation.
🤔
Sounds like the FCC chair is taking his orders from Musk
