+FitzgeraldFamily Posted April 24, 2010 Share Posted April 24, 2010 (edited) Okay, below is the information about the new IIF satellites that will soon launch which will provide us with much improved accuracy... do you think this will make the sport of geocaching to easy and eliminate a good portion of the hunt? I personally enjoy getting in the vicinity of a cache then hunting for it, rather than being within 2 feet and grabbing it right away... With this new system overhead tree's/brush wont affect signal... I hadn't seen much talk about this so i figured id start a topic. The global positioning system works fine if you’re trying to persuade your phone to point you to the nearest bar or untangle a freeway interchange. But it’s not exactly accurate — GPS can be off by 15 feet or more, and the signal degrades when confronted with tall buildings and trees. It even gets screwed up by the slightest electromagnetic interference, like stray radio waves or storms in the ionosphere. Hopefully this will soon be a distant memory. In May the Air Force will begin launching the so-called IIF generation of GPS satellites, which will eventually replace half the existing armada. The new birds each transmit three civilian GPS signals — we’ve typically been making do with just one for years — including a military-strength transmission that should enable autopilots to land with zero visibility. A three-signal world will mean always-on GPS that’s accurate to within 3 feet, even indoors and in concrete urban canyons. Forget finding the bar; you’ll be able to geolocate your stool. source: http://www.wired.com/magazine/2010/04/st_gpsreboot/ Edited April 24, 2010 by FitzgeraldFamily Quote Link to comment
