Because of economics. On the ground you an afford to use a big transmitter and a big antenna, while on the satellite both have to be smaller. Therefore most of the power and the gain happens at the ground station.
Communication - Power Station song - was created on 1985-10-28.

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.
wastage of power
To build a satellite, you need to first define its purpose and specifications. Then, design the satellite components, such as structure, power systems, communication systems, and payloads. Finally, assemble the components, test the satellite thoroughly, and launch it into orbit.
A satellite docking station is a place where you can power up all of your electronic devices, such as your phone, PDA, iPod, camera, etc. This will ensure that these items will last so that you may use them for long periods of time.
The Traveling Wave Tube Amplifier (TWTA) is widely used as a power amplifier in satellite communication systems. It amplifies signals in the microwave frequency range and is capable of providing high power output with low noise and distortion. TWTA technology has been utilized for several decades in satellite communication due to its reliable performance and efficiency.
The three basic requirements for a satellite are: Proper elevation, Proper speed, and Proper orbit. If a satellite does not have these three things it will either float into space or crash into the earth.
Auroras can disrupt satellite communication and navigation systems, cause power outages by inducing electrical currents in power grids, and create radio signal interference which can impact communication systems.
Satellites are usually fitted with a re-chargeable battery, and solar panels. The solar panels absorb energy from the sun, and the batteries store the energy for use by the satellite.
Interference in satellite communication refers to the disruption of signal transmission caused by unwanted signals or noise, which can degrade the quality of communication. This interference can arise from various sources, including other satellites, terrestrial communications, or even atmospheric conditions. Effective management of interference is crucial for maintaining the integrity and reliability of satellite links, often involving techniques such as frequency coordination, power control, and advanced signal processing. Mitigating interference ensures clearer communication and maximizes the efficiency of satellite networks.
A type of communication level in which one converses/communicates with spirits or someone of a higher power; GOD. (A divine)
