visit trimble and mercator sites.

In principle it is detemination of intersection of circles and you are given the centre and radius of each of the circles(minimum 3 max - 14)

How to know each GPS satellite position from DoD?
Something equipments on GPS satellite?

The DOD has placed it in the known orbits. There for they know the satellite positions fairly each secons. Then they have observatories that they use for adding small corrections to the orbital parameters. These params are passed by navigation message and user can caluculate the satellite postion very accurately.
