    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.

    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.

      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.

    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.

      These guys don’t care. They’re a bunch of gangsters trying to profit by dismantling the government and selling corporate replacements for its services.

      We’re either headed towards long term fascism or a massive civil backlash.

        Yeah, imma have to go through our equipment to find out if they go through with this. If we do have to replace it, this shit is not cheap.

    That’s weird, I always viewed GPS as a form of American Imperialism. Sure, it’s a bit extreme maybe, but America does own and operate it and jam it when enemies try to use it.

      Calling GPS part of imperialism is a stretch. It was put in the air at no cost to another country and can be used without cost by anybody, but nobody has to use it. Other countries can launch their own satellites if they want, but they don’t because that’s expensive and GPS is free. The US isn’t making money off of it or exploiting another country with it.

      Yes, the US can jam it regionally when in conflict but of course why wouldn’t we? No reason to help the enemy.

        They do, and they did:

        EU (not a country, but still) - Galileo

        Russia - GLONASS

        China - BeiDou

        They all have their own.

        technically, originally the GPS system was private, until made public, where it had error obfuscation, until semi recently it was released fully.

        It was originally funded by the US government, still is, it’s just publicly accessible now.

        (the original usecase being for shit like ICBMs and what not, obviously)

      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.

    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

    I really hope this means another attempt to use the magnetosphere itself. MAGNAV might actually be possible at this point.

    Edit: better article. AI advancements make MAGNAV a real possibility now. https://www.af.mil/News/Article-Display/Article/3408951/magnav-project-successfully-demonstrates-real-time-magnetic-navigation/

      How does that handle high tension lines and the like, doesn’t it disturb the magnetosphere far too much? Kinda the reason even compasses don’t work anymore in town?

        this would also be susceptible to magnetic field switching as well, shouldnt be a huge technical limitation, but im not sure accuracy is going to be quite as good.

        No idea. I think there’s a lot of machine learning - enabled mapping up front.

    I hope I’m not reading into this too much and thinking he just wants to use Russias standard of satellite technology. L5 GPS is better accuracy. Also if you look at 3GPP’s future planning and goals, the game is to utilize all RF technology together. 5G broadcast and LoRaWAN will make sensors happens within cities and highways and that working together with GPS and cell, you can get readings about a foot or less.
