There is none, we let them fall.
Thousands of pieces of manmade space-junk fall back to earth every year, not one piece has ever harmed a human being. The earth is big, we are small, and most importantly, most of the junk burns up in the atmo : D
Earth and the other members of our solar system are satellites of the Sun.
The system of satellites used for determining location on Earth is called the Global Positioning System (GPS). It consists of a network of satellites that orbit the Earth and transmit signals to GPS receivers, allowing them to accurately determine their location, speed, and time anywhere on the planet.
Communications satellites, launched in the 1960's. There were 2 Echo satellites, which were passive (the signal would bounce back to earth like a mirror). The Telstar satellites were active, meaning that the signal was retransmitted back to earth.
Unfortunately, a GPS is a receiver only. It locates its position on the surface of the earth by determining its distance from a series of satellites. It does not transmit any information back to the satellites, which would be necessary for a satellite to locate the GPS.
The Earth's Moon, Jupiter's four "Galilean" satellites, Saturn's "Titan", and Neptune's "Triton".
the solar system contains satellites that provide "solar power"
Moons are considered satellites, hence several planets in our solar system have satellites: Neptune, Earth, Mars, Saturn, Uranus & Jupiter.
Some well-known satellites orbiting Earth include the International Space Station (ISS), the Hubble Space Telescope, and the Global Positioning System (GPS) satellites. These satellites serve various purposes, such as research, communication, navigation, and monitoring Earth's environment.
The equipment that is sent from earth to distant parts of our solar system is satellites.
Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
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.
Satellites take pictures and accumulate other information into the computer. They analyze the data and send it back to weather stations on earth.
