First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
SatellitesSatellites orbit in outer space, not in the earth. They are sent to outer space where the gravitational pull of the earth pulls them around, just as the earth is pulled around the sun in a similar manner. The layer is the exosphere. It greatly depends on what the satellite is for and who owns it how far up it orbits. Imaging satellites need to be close to the Earth, so they orbit about 130 miles up. Communications satellites are generally at 23,000 miles up. GPS satellites are up about 13,000 miles.
The remote sensing device that uses a system of 27 satellites transmitting microwaves is the Global Positioning System (GPS). These satellites orbit the Earth and provide location and timing information to GPS receivers on the ground. By analyzing the microwave signals received from multiple satellites, GPS receivers can calculate precise positions anywhere on Earth.
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
Geostationary satellites are the ones used for GPS satellites.
There are currently 30 healthy GPS satellites in orbit.
GPS satellites are in Medium Earth Orbit (MEO) at an altitude of approximately 20,000 kilometers. This allows them to provide global coverage while being close enough to maintain accurate signal transmission to receivers on the ground.
GPS satellites orbit the Earth at an altitude of about 20,000 km in medium Earth orbit (MEO). They move in precise paths to ensure global coverage and are spaced evenly to provide accurate positioning data. The satellites follow elliptical orbits that repeat every 12 hours.
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.

Satellite. Satellites can be natural, like the Moon, or artificial like GPS satellites.

The GPS satellites are not in geo-stationary orbit, but instead orbit twice every time the Earth rotates once. This means that for any observer the satellites appear to orbit once overhead each day. Such an arrangement gives better coverage. It is also clever in the sense that the motion of any GPS satellite will repeat itself each day. The GPS constellation of 24 satellites are arranged in six different orbital planes, each inclined 55 degrees to the equator. To obtain exactly two orbits per day, the satellites are placed at an altitude of 20,200km!!!
Most communications satellites operate outside of the earth's atmosphere. The GPS satellites are about 23,000 miles from the surface of the earth.
GPS was not invented for forty years after WWII ended. GPS depends on satellites orbiting the earth. The satellites get there by rocket. The first satellite did not orbit the earth until 1957.
