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.

What is satellite footprint?
A satellite footprint refers to the area on Earth's surface where the satellite signal is received. It is the geographical coverage range of the satellite's signal transmission. The footprint size and shape depend on factors like satellite altitude, beam characteristics, and antenna design.
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 a satellite VPID?
A satellite Video PID (VPID) is a unique identifier that is used to assign a specific video stream within a satellite transmission. It helps receivers to identify and decode the video data accurately from the satellite signal.
What is signal strength loss during transmission?
pch Answer: Attenuation
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
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.
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.
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.
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 Eclipse effect in satellite communication?
The eclipse effect in satellite communication occurs when the satellite passes into the shadow of the Earth, causing a temporary loss of communication signal. This happens during solar eclipses or when the satellite is behind the Earth in its orbit. To mitigate the impact, satellite operators can use battery power or pointing strategies to maintain connectivity during these periods.
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.
