Something about Physics and Global Position System(GPS)

[mythguy]

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 want to 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 don't 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.

yes, thank you
