It uses 66 small satellites in low earth orbit
Yes
Every GPS unit needs a minimum of four (4) satellites to compute a 3-dimensional position, and performs more accurate calculations with more satellites. I think my TomTom is capable of using 12 simultaneous satellites if it can see that many. Yours may be different.
GPS satellites are used to help us accurately determine the current time and our location. GPS satellites are not directly used to help us predict the weather. Weather satellites use many imaging and sensing technologies to help us predict the weather, but they are not useful in helping us determine our location. They are two different types of satellites with two different purposes. There are many other types of satellites too, such as communication satellites (such as used with Direct TV), space telescopes (such as Hubble) etc.

It is a $4 billion system that was developed to connect calls around the world via 66 small satellites in low earth orbit

Calling an iridium satellite phone depends upon which country one is calling from. If one is calling from the United States, he/she must dial the prefixes 011--8816 followed by the eight digit phone number. However, if one is calling from a country such as Germany or Mexico, he/she would instead use the prefixes 00-8816. Australia, for instance, uses the prefixes 0011-8816 to dial an iridium satellite phone.

You need 4 to locate a position. There are 24 satellites in use in the sky with 8 spares.
There are many satellites that Dish Network uses.
