The up-and-down propagation delay for a satellite link is primarily determined by the distance to the satellite and back to Earth. For geostationary satellites, this distance is approximately 35,786 kilometers, leading to a round-trip propagation delay of about 240 milliseconds. Consequently, while the link operates at 1 Mbps, the effective throughput will be impacted by this latency, especially in applications sensitive to delay, such as real-time communications.

How do airplanes communicate?
Most planes have VHF radios. Military planes have UHF radios, and some planes have satellite communications.
How do you communicate with sattellite?
For example when you send a text message your message gos up to satellite and then bounces off towards the recipient.
How do people on Australian sheep stations communicate with the outside world?
People on Australian sheep stations often rely on a combination of satellite phones, two-way radios, and, increasingly, mobile phones to communicate with the outside world. Given their remote locations, these technologies are essential for daily operations, emergencies, and staying in touch with family and friends. Some stations also use the internet via satellite connections, although connectivity can be limited and intermittent. Overall, these communication methods help bridge the isolation of rural life.
What is first communication satellite?
The first communication satellite was Echo NASA
What is the frequency range in satellite communication?
The satellite transponder typically works in either the C-band (4-8GHz) or the Ku-band (12-18GHz) and these are for the downlink (from the satellite to the earth station).
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.
Did tv stations air their brodcasts from space?
No, TV stations do not broadcast their programs directly from space. Satellite communication technology is used to transmit signals from Earth to satellites in space, which then retransmit the signals to users on the ground.
How does a satellite and an object work together?
A satellite orbits Earth and can be used to monitor or communicate with objects on the ground. For example, a weather satellite can track storms and communicate weather data to ground stations for analysis and forecasting. In essence, a satellite and an object work together through information exchange and monitoring capabilities facilitated by the satellite's orbit around Earth.
How do you communicate an area affected with earthquakes?
Your best chance of communication is by a satellite enabled device .
Does skype offer a good quality satellite phone?
Skype phones are not satellite phones. They are phones which connect to Wi-Fi and then run the Skype program to communicate with other phones. You can use them to call satellite phones, but they do not offer satellite phones.
What has the author Warren L Flock written?
Warren L. Flock has written: 'Propagation effects on satellite systems at frequencies below 10 GHz' -- subject(s): Artificial satellites in telecommunication, Engineering meteorology, Radio wave propagation
What exactly are satellite phones?
Satellite phones are powerful portable phones which communicate directly with a satellite, eliminating the need for a cell tower. Satellite phones are extremely useful in areas that are desolate, like the desert or at sea where phone signals from towers will not reach.
When were satellite phone systems invented?
According to multiple websites of information on satellite phone system, satellite phone systems were invented in the year of 1979. Satellite phone systems make it possible for people to use their cellphones and communicate to each other.
What is look angle?
the look angles are the angles to which an earth station must be pointed to communicate with the geosynchronous satellite
What do satellite engineers do?
If the company has to communicate with satellites up in space, then the engineer would be the one to help it happen. They are the ones who access the satellite and make sure that all of the information that is relayed is correct and what they are after.
Why are ground stations in continuous contact with satellite in geostationary orbit?
Since the satellite appears fixed in the sky, antennas can also stay in a fixed position to communicate with it, and don't need to be continuously guided.
How do airplanes communicate?
Most planes have VHF radios. Military planes have UHF radios, and some planes have satellite communications.
