  1. GPS Journals and Conferences by highways · · Score: 2, Informative · on Best Way To Publish an "Indie" Research Paper?

    Vincenty http://en.wikipedia.org/wiki/Vincenty's_formulae is the current benchmark for distance between two points. If you think you've done better, you've got two real options:

    (1) A GPS/Navigation Journal, or
    (2) Surveying journal

    Forget computer science - not really interested in this problem.

    As far as conferences are concerned, it's worth trying to get into one of the following:

            * IEEE PLANS http://www.plansconference.org/

            * ION PLANS http://www.ion.org/meetings/

    If you think it's still good for a journal, look for who has cited Vincenty's paper in Google Scholar - it will give you a good indication as to what journals to chase.

  2. It sounds as if it's not just GPS by digitig · · Score: 1 · on Best Way To Publish an "Indie" Research Paper?

    From your description it sounds as if it's an algorithm that's more general than just GPS. Maybe it works for all hyperbolic positioning systems, or maybe even for all positioning systems. I'd look at the journals and conferences of the Institute of Navigation and Royal Institute of Navigation.

  3. Re:Seems silly to use this. by MichaelSmith · · Score: 1 · on Batteries To Store Wind Energy

    In a stationary mount, you don't have to worry about gyroscopic affect

    Not completely accurate. The rotation of the Earth will cause a stationary gyro to put some torque on its bearings, depending on your latitude, just as a Foucault pendulum veers over time. It's not a big effect, but there are no "small effects" when we're talking about gigawatts of kinetic energy :)

    You just need to align the axis of rotation of the flywheel with the axis of rotation of the Earth. As a bonus you get a way to avoid adding leap seconds to UTC.

    About half of my conference papers were written in various versions of OOo, dating back to build m645 or so. The other half I did in TeX.

  6. Autonomous Lawn Mower Competition by Tekmage · · Score: 5, Informative · on Building A Homebrew Robotic Lawnmower?

    There was an Autonomous Lawn Mower Competition going on earlier this month - saw it mentioned on robots.net

  7. I hope this passes. by thogard · · Score: 2 · on Oregon Considers GPS-based Road Taxes

    I've been wanting to get my hands on a GPS constellation simulator (like this one)ever since I saw one at GPS ION years ago. The problem is US$20k is a bit over my price range for a toy that would provide such a small window of entertainment. If this law happens, then I expect an open source sim within weeks complete with schematics, borad layouts and of course code.

    on a semi OT note: There will be a civil GPS users meeting Downunder in Feb if anyone has any feedback they want to give the US govt about the system.

  8. Radar Detectors, Laser Detectors, Now GPS Jammers by cybrpnk · · Score: 4 · on Using GPS To Catch Speeders Found Illegal

    So what if you rent a car with an onboard GPS. With massive research like this underway, it's just a matter of time before you can get a local jamming unit that would wipe out a cheap GPS receiver's ability to pick up the satellite data. (Actually this has already been done...and discussed on Slashdot!) Then, of course, the rental car companies would get into anti-jamming technology so the thing to do is just wait until NOT having a GPS onboard becomes a market differentiator (and way to charge more)... What would really be cool is locally spoofing a GPS signal set so the record showed you went to places (at speeds) that you really didn't....
