There are over 1000 operational satellites orbiting the Earth, and probably 10,000 pieces of "space junk" also orbiting the Earth.

We don't need to protect our satellites because their is not yet warfare in space where our satellites are.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
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.

The Sputnik satellites were the first sucessful satellites, launched by the Soviets in the 50's.
Natural satellites, we only have one - the Moon - helps us by providing a bit of moonlight at night, and also plays a role in stabilising the Earth on its axis. Artificial satellites helps us with navigation, communication, weather forecasts, pictures of the Earth and surveying.
