US GPS, EU Galileo to Work Together

saintory writes "The US and EU are in talks to allow their separate GPS systems to work together. The future uses would allow enhanced location information based on two readings, among other benefits. 'The market probably will drive dual-use receivers. We think probably that single (U.S.) GPS-specific, or Galileo-specific receivers — the market will phase out in time [...] It just doesn't make sense to limit yourself to just one system'."

    Actually, citizens haven't had globally downgraded signals since May 1st, 2000. The US military found it could regionally downgrade signals to protect sensitive locations while allowing people in general to have full access to GPS.

    Misguided or not, the missile shield is not intended to divide you. If you want to argue that will be an unfortunate side effect, that's one thing, but if you seriously believe that it's part of a strategy of divide-and-conquer, then I truly think you're putting motives in there that don't exist.

    Now, assuming that you merely meant that it would be an unfortunate side effect, you also should realize that Poland and the Czech Republic dearly want us to put the missile shield in their countries (or at least their governments do). I'm not arguing that's a sufficient reason to do so - I'm just pointing out that we're not imposing this on them. They want it. This came out quite strongly after Putin suggested that it be put in Azerbaijan instead, if the goal was truly to protect Europe from a Middle East attack.

    How old are your GPS receivers? I use headless (no display) SiRF III-based receivers that sell for under $70 and they work indoors where my older, expensive Garmin units don't, and rarely give a fix less accurate than 30 feet. And that's with the built-in patch antennas.

    I think Garmin's new handheld units (the GPSmap 60CSx I'm sure of) use the SiRF III chipset. If you're going to carry a GPS receiver for backpacking, get one of those, carry a couple extra sets of lithium batteries, and you're set. I still recommend carrying topo quads and a compass, just in case. Also, bring a ruler along and make sure you understand how to plot GPS readings on the map by hand. It's really not that hard, and a 7.5" quad beats a tiny GPS display any day.
