First modernized GPS satellite Launched

Posted by Hemos on from the keeping-up-with-the-neighbors dept.

A reader writes "The first GPS 2R-M satellite has launched from Cape Canaveral, Florida on top of a Boeing Delta 2 rocket. The government is now competing with Europe's Galileo system, and has added two additional military channels and one civilian channel, which will increase the accuracy and performance of GPS - as well as increase its resistance to jamming."

  1. How do you compete with vaporware (Galileo)? by Anonymous Coward · · Score: 5, Insightful

    " The government is now competing with Europe's Galileo system "

    Lets see :
            Galileo has not launched yet.
            Galileo will not be free.
            The 2R-M was planning before Galileo was anounced.
            Galileo operational capibility is not planned until 2008.

    I'm failing to see the link to the vaporware...

    You have to remember that they're overengineering these things by terrestrial standards, because the satellites have to withstand some fairly harsh conditions while in orbit (such as radiation, EM storms from solar flares, etc). I imagine they're also hardened to some degree against human-generated interference, given all the worrying the Air Force has been doing lately about space warfare. Given all that, I'm not surprised that they seem excessivly bulky by the standards of present technology.
