24 GPS satellites carry atomic clocks

    Quoted from http://hyperphysics.phy-astr.gsu.edu/hbase/gps.html#c1"

    How do they know which of the points is the correct one? (see sentence in blod)

    Thank you!:approve:

    I took a guess that one of the points doesn't lie on surface the Earth, and it seems that I was partially correct - see http://www.trimble.com/gps/how.html" [Broken].
