For most of the time, the only loss is the small amount absorbed by the atmosphere, which isn't significant. There is somewhat more loss temporarily, when the RF signal goes through rain. The major cause of the apparent loss in signal strength at great distances is the fact that the transmitted signal spreads as it covers more distance. So the farther you are from the source with an antenna of a certain fixed size, the less power your antenna collects, because the power is spread thinner.

How do you convert analog signal to digital in satellite transmission?
You sample the signal to get a number, base that number in binary, and store it. Do it often.
What is the speed of a satellite signal?
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
What is signal strength loss during transmission?
pch Answer: Attenuation
Why No signal from satellite?
There are many reasons why you may have no signal from your satellite. Your service could have been disconnected for example.
Why is satellite communication not widely used for mobile communication.?
In satellite communication uplink (transmission of signal from earth station to satellite ) & downlink (reception of signal from satellite to earth station) takes place TX & RX involves a finite amount of delay which is acceptable in data communication, but i audio & video TX this delay is unacceptable, overlapping/ alaising causes errors which demodulated by qpsk.
What causes the sporadic loss of satellite signal?
The satellite signal uses microwave radiation and water absorbs microwaves. So when it rains or there are thick clouds the signal from the satellite gets absorbed and if enough is lost by this process your Dish Network receiver will lose signal
Why does satellite radio fade out?
The satellite signal can be blocked by various things.
What is satellite receiver?
A satellite receievr, is a tv receiver, which connects to the satellite anntena, than to your tv, and decodes the information coming from the satellite signal into video and audio signal, so you can watch tv channels.
Do satellite dish covers affect reception?
strong rains and thunderstorm slightly affects signal blizzard covers the satellite dish with snow strong wind dislocates the position of the satellite dish strong heat, sometimes, can melt components of the satellite dish such as the surface of it
What is the purpose of a satellite antenna?
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
What are telecommunication links?
In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.
How does gpss work?
It sends a signal directly to the satellite and the satellite pinpoints the location of it.
