simple question about satellite position

Hello all
anyone could give me an hints (a link to a resource or a site) on how
to obtain satellite position starting from azimuth and elevation from a
site?
thanks all

You need to better explain what you want. If you mean where the satellite
is in space, the azimuth and elevation from a single site are not sufficient
information to find that.

You're true...
I need to know GPS satellite position, i've data of about 10 igs gps
station with relative rinex data and also elevation and azimuth of
every satellite for all stations.
i need to know satellite position for tomographic purposes
Thanks in advance

What are you trying to accomplish?
Free Trimble Planning software might be what you want.
It will allow you to plot obstructions around multiple GPS receivers, and
you can see detailed information about the location of all satellites at a
given point in time.

You "import" the current almanac as an ssf file from the download page.

Are you looking for a geostationary satellite, like DirecTV or Dish?
Their web sites have satellite locators, given your zip code ot lat/long
that return azimuth and elevation.
