Something about Physics and Global Position System(GPS)

  1. Oct 22, 2009 #1
    Hi all,
    Im a international student and studying a project about expain Physics used in the development and use of the Global Position System(GPS)

    I just wanna get some ideas about where I can start to do research. I mean did some one give me some points and infomations for this topic?

    Those are what i know so far:
    1: definition of GPS
    2: 3 satallites can locate a point, then can find out the location and distance.
    3: using clock can find out the location precisely. (Actually i dont understand what's 'clock' technology using in GPS)

    I suggest you read http://en.wikipedia.org/wiki/GPS
    You could include the physics of the satellite orbits. I would be interesting to find the length of time a satellite is above the horizon on each orbit and how that varies with orbital radius.
    The affect of timing accuracy on the calculated position could be calculated.
