GPS Slowly Changing How Things Are Done
Hemos forwarded me a link to a story at Fast Company about how GPS is changing the way people do business. Several good examples are used, from farmers in Alabama to anti-theft devices. Some notes on GPS' military origins as well. Also worth noting is how GPS, like computers, wasn't adopted overnight, but rather over time as applications were found.
I have a Garmin GPS V and LOVE it. The turn-by-turn routing has been a huge help. We started looking to buy a house and would print out a ton of MLS listings. Without the GPS we'd have to spend a lot of time planning our route. With the GPS we just punch in the address of the next house and off we go. Very accurate.
My father and I use GPS receivers as often as possible. We are both Geocachers.
For those of you that don't know what Geocaching is, here is a quote from the geocaching.com FAQ:
"What is Geocaching?
Geocaching is an entertaining adventure game for gps users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a gps unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet. GPS users can then use the location coordinates to find the caches. Once found, a cache may provide the visitor with a wide variety of rewards. All the visitor is asked to do is if they get something they should try to leave something for the cache. "
Wardriving is a perfect example of how GPS has changed the way we look at computer security, especially where wireless LANs are concerned.

Can someone enlighten me as to why a farmer driving a tractor would need to know their location to a 1' accuracy?
The mind boggles. How many people are going to accept a system that lets their insurance company track everywhere they drive? Yes, I'm surely more obsessive about this kind of thing than Joe Average, but surely you don't have to be a privacy nut to have some issues with this.
Any sufficiently advanced technology is indistinguishable from a rigged demo

Like utility infrastructure. I work at a water company, and before a contractor burries pipeline, we use RTK (realtime kinematic) GPS to record its location down to 0.04' (or 1cm). So when line locators need to mark facilities its much more accurate. Normal GPS isnt that accurate, but we use base stations and radios to send correction data in real time out to the GPS collection devices.

If you're not outraged, then you're not paying attention.
We had to pay $60,000 for a rack mount GPS unit for the research ship I was on. We only got 2 or 3 satellite fixes and even then that was for only a handful of hours a day because the constellation wasn't complete. But by cracky we loved it! It was good enough then and by god ... by god... what we wouldn't have done for one of those modern sub $200 contraptions. Oh yea and a full constellation of satellites.
Navigation for scientific research (gravity & magnetic surveys) was interesting. We'd post process and combine a few hours of GPS a day, Transit Sat Nav (crude sat fixes + dead reconing), plus ARGO ranging navigation. The cool thing about ARGO was that it required shore stations where someone had to be by the transmitter for several weeks. And since the cruises were in the Carribean and off Brasil, sitting around a shore station (aka "the beach") for several weeks was pretttty fine.
