Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
The ionosphere is the layer in the Earth's atmosphere responsible for bouncing back radio signals. It is composed of charged particles that reflect radio waves, allowing for long-distance communication via radio transmissions.
A Global Positioning System (GPS) is a system that uses signals from satellites to provide precise location information on Earth. GPS receivers can calculate latitude, longitude, altitude, and time data to determine an exact location.
Radio and TV signals are reflected back to Earth in the ionosphere, specifically in the F layer. This layer is located approximately 150-500 kilometers above the Earth's surface and is characterized by its ability to reflect high-frequency radio waves.
Yes, the thermosphere plays a significant role in impacting Earth. It is the layer of the Earth's atmosphere where many satellites orbit, and it absorbs harmful radiation from the sun, protecting us on the surface. Changes in the thermosphere can also impact radio signals and communication systems on Earth.
The Global Positioning System (GPS) is a technology system that uses satellite positions to identify location on Earth. GPS receivers pick up signals from a constellation of satellites orbiting the Earth to determine an accurate position.
None. The Moon itself is a satellite of the Earth.
A satellite is like a mirror in the sky. Only instead of reflecting light, it "reflects" radio and television signals. There are receivers and transmitters in the satellite, so what it receives on one frequency (or channel) can be then re-transmitted back to earth on another frequency. Its like sending out signals from a tower that is many miles high to reach out to a bigger area. Only without the tower!
Because you are in space. If you try calling someone in space, he or she wouldn't hear you.
YES
yes
u tell me
How do THEY get back to earth?!
A GPS uses satallites to identify location
The LM had an antenna array that could beam signals to Earth. When the astronauts were out on EVA, their suits had radios which beamed signals to the LM, which in turn sent the signals to Earth. The LM acted as relay between the Earth and the suit radios.
The moon does not block radio signals sent from Earth, but it can cause disruptions in the signals due to its influence on the Earth's ionosphere. Radio waves can still reach the moon and be reflected back to Earth. NASA and other organizations have successfully sent signals to spacecraft on the moon and beyond.
The far side of the moon would receive the same signals with the exception of Earth originating signals. The radio equipment would not be subject to interference from the Earth signals on the far side so space originating signals would be easier to study.
Earth has been broadcasting radio signals into outer space since the late 1800's.
