How do satallites get signals from earth?
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.
What is an instrument sent to space to relay information back to earth?
A satellite.
What happens to the laser light when it reaches the satellite in the ranging system?
When the laser light reaches the satellite in a ranging system, part of the light is reflected back towards the Earth. By measuring the time it takes for the light to travel to the satellite and back, the distance between the Earth station and the satellite can be calculated with high precision. This helps in monitoring the satellite's position and orbit.
What gathers information and sends it back to earth?
A satellite is a device placed in orbit around Earth that gathers information, such as images or data, and transmits it back to Earth. Satellites are used for a wide range of purposes, including weather forecasting, communication, and mapping.
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
What is a communications satellite?
Satellite communication is when a signal gets sent to space, bounces off of a satellite, and comes back to Earth. This is a very common source of communication.
What is a satellite probe?
an unmanned device that uses technology and sends information back to earth
What is the difference between a space probe and the satellite?
Space probes- instrument that gathers data and sends it back to earth, and an artificial satellite is when people go up to space and gather data and then go back to earth to go over the data
What NASA space shuttle recently came back to earth?
discovery
What keep a satellite in its orbit around?
Gravity wants to pull the satellite back to Earth - the speed the satellite travels around the Earth wants to fling it out into space. The two forces cancel each other out, and so the satellite remains in orbit - pulled in opposite directions with equal force.
How does SATCOM work?
An earth terminal transmits data up to the satellite. The satellite can then either shoot it right back down in its footprint to another earth station where the data was meant to go. It can relay it directly to any amount of other satellites and then down to the other earth terminal you were wanting to talk to. Or it can go up to the satellite, back down to another terminal, up to another satellite, and then down to where you wanted to "talk" to.
How does a satellite take a picture?
A satellite takes a picture by capturing light reflecting off Earth's surface with its onboard camera(s). The satellite's imaging system converts the light into digital data that is transmitted back to Earth for processing and analysis.
