Uplinking and Downling frequencies.

[SENTHIL KUMAR]

UPLINKING AND DOWNLINKING FREQUENCIES.

A satellite receives, television broadcast from a ground station from different locations .
This is termed as “Uplinking” because the signals are sent up from the ground Station to the satellite.

These signals are modified in to another level frequency and amplified by satellites.
Then the signals delivers to the footprint area , a process called “Downlinking”.

Uplinking and Downlinking are shown .

​

Both the uplink and downlink signal are travel in the same space.
To ensure that the signals do not interfere with each other, separate frequencies are used for uplinking and downloading
