Hi,
How many GPS satellites are there ? some web sites say that they are 24, while others like the
"US Naval Observatory" web site say that they are 32.

Quotes from Wikipedia:

The U.S. Department of Defense (DoD) developed the system, which originally used 24 satellites.

As of February 2016, there are 32 satellites in the GPS constellation, 31 of which are in use. The additional satellites improve the precision of GPS receiver calculations by providing redundant measurements.
