If you thought that the GPS signal on your phone was just there for you to find your way around in a new town or country then think again. The GPS service is the worlds most accurate public clock and as such has found its way into almost every way of life and business.
So what might happen if it were to disappear one day?

  1. We did just fine for thousands of years before GPS and computers and cellphones. It'd be an Inconvenient nuisance, not the end of the world. None of this stuff was even widespread before the 80's. We'd be fine.

  2. Youve been doing good so far thus far huh? and look how far youve flown…. good thing there is a universe space ship refuel station like space a giant race track… with pit stops…..

  3. Thank you for the video. I watched it already some time ago, but YT proposed it again and I watched it again.
    I'm a mechanical watch lover, so I watched the ad, too. Nice mechanic solutions for the watches in the ad.
    Thanks,

  4. 03:18 – that will be general relativity.
    Special relativity relates to velocity while general relativity relates to gravity.
    Although they have to compensate for both special relativity – the velocity of the satellite and general relativity – the gravity of Earth.

  5. I remember growing up when I wanted to set my Casio watch I would call the landline phone number 853-1212 and the digitized female voice would say..
    AT THE TONE THE TIME WILL BE…
    And you could zero your seconds to this tone and be synchronized for a couple weeks or less.
    Now my GPS watch is synchronized every time I use it.

  6. I am a shade puzzled by your appraisal at the end. If LORAN could be used to replace GPS for a timing mechanism, …I should think VOR could too. Granted, VOR serves airborne craft, yet I should think a person could use it on the ground in a pinch.
    We have VOR stations all over the place in the States…. I've generally understand they're still there in no small part in case GPS has trouble for some reason…..

  7. we got along for thousands of years without gps. if it failed like it does alot how hard would it be to buy a map and use a map. maps never have signal issues or run outta juice

  8. Excellent and super-informative video. I'd really like to see a follow-up on what changes may be possible going forward. It is entirely possible to do extremely precise reckoning, entirely ground-based, using lasers and other means. This would have its own set of major advantages. Overall, the best approach will end up being a highly distributed system, using both satellites and ground systems, with very sophisticated co-ordination between the different components. If done right, this would be far more reliable in the face of various possible disasters, and much more precise under normal circumstances.
