I did this in my final year thesis at uni. Worked pretty well in the royal college building at strathclyde. Didn't work quite as flawlessley as I would ahve liked but then I was just one under grad not quite the same scale as nokia!
GPS is fine if you just need directions from your office to a restaurant, but it’s not much help for finding your way around a building. So Nokia has developed a form of indoor GPS. According to a post of the Finnish firm’s Conversations website, Indoor Positioning could – potentially – help you find places and items indoors, …
You could ape exactly the way GNSS systems currently work. And without the need to derive out some of the non-dispersive errors it should be pretty accurate.
All the system would need to do is rewrite the almanacs to include stationary ground-based transmitters but I'm pretty sure that's already included in the protocol.
I had a pretty neat prototype working using a combination of solid state giros and traditional GPS 5 years ago when I worked at ****. Of course we had drift, but most of that was down to our crude prototype manufacture and we reckoned on a much greater improvement if we got the giro alignment more true to the orthogonal. Then we all got fired as **** closed their UK research arm. ****
Supermarkets don't want you to find your can of beans. Not immediately, anyway. The layout is designed to make you wander endlessly through all the aisles looking for that elusive can of beans which, this week, is located next to the baking accessories. Next week it'll be across from the salad dressing, just in case you memorised the floorplan. The longer you walk, the more you buy.
You joke about it - but I once had to calm my father-in-law when he found out there was a code that could shut down the entire internets, after the guys in Spooks saved us all from it falling into the wrong hands, had they not planes could fall out of the sky, banks would collapse, the economy would go into meltdown, and countries would be at each other throats preparing for war.
I laughed and explained it was just a TV program, and that it couldn't be that simple otherwise nobody would use it.
But now look... Phorm starts pissing about with ISPs in the UK, and within a year or so the world is in crisis, planes falling out of the sky, banks collapsing, economy in meltdown, and everybody is fighting everybody else..... if only I'd of listened.... if only we all had...........
