    GPS isn’t just for google maps. I’m a land surveyor and we literally use GPS every single day. Without it we’re basically fucked. We do hydrographic surveying and without GPS we’d have to basically go back to analog as 90% of the equipment on our boat would be useless. Good luck figuring out how much water is left in the Colorado river without it.

    Im not exactly an expert on this, but i am very familiar with what my job requires. The National Geodetic Survey (NGS) will be completely fucked without it as it’s built on decades of data and monitoring. You can’t just look for “alternatives.” Whatever Elmo has is not robust enough for the precision that is required for what we use GPS for. And without shit like that you couldn’t hit the broad side of a city.

    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.

      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.

      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.

    There’s already a startup trying to get the FCC to give them half of the 915mhz band (meshtastic, smart home stuff, ELRS, ham radio) for a pay to win GPS alternative.

    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

    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:

    https://www.nianticspatial.com/locate#vps

    https://arstechnica.com/ai/2024/11/niantic-uses-pokemon-go-player-data-to-build-ai-navigation-system/

    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.

      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.

    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.

    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.

      My phone uses the Graft Positioning System to tell me where I can go and who I can talk to.
