Satellite Communications



.ppt  Satellite1.ppt (Size: 202.5 KB / Downloads: 365)
Basics: How do Satellites Work

Two Stations on Earth want to communicate through radio broadcast but are too far away to use conventional means.

The two stations can use a satellite as a relay station for their communication

One Earth Station sends a transmission to the satellite. This is called a Uplink.

The satellite Transponder converts the signal and sends it down to the second earth station. This is called a Downlink.

Basics: Advantages of Satellites

.The advantages of satellite communication over terrestrial communication are:

The coverage area of a satellite greatly exceeds that of a terrestrial system.

Transmission cost of a satellite is independent of the distance from the center of the coverage area.

Satellite to Satellite communication is very precise.

Higher Bandwidths are available for use.


Basics: Disadvantages of Satellites

.The disadvantages of satellite communication:

Launching satellites into orbit is costly.

Satellite bandwidth is gradually becoming used up.

There is a larger propagation delay in satellite communication than in terrestrial communication.

Communication

The technique which helps to transfer information from one place /node /terminal /device to another is called communication.

Why satellite communication?

Microwave band of frequency is used
High frequency waves travel in straight line
Earth is curved
Solution: satellite
An earth station transmits the signal up to the satellite-called the up-link and is transmitted on one frequency.
The satellite receives the signal and retransmits it on the down link which is on another frequency.

Why not moon?

concept proved by naval research lab in Washington D.C.by using moon in 1940’s.
Surface of the moon is tough and uneven that most of the signal scatters back into space instead of bouncing back to earth.
Moon can only reflect signals. Modern communication satellites actively rebroadcast the signal back to earth.
Moon is only available for half of the day, and it keeps moving. Earth based antenna have to move to track it.

Advantages of satellite communication

Provision of service to remote or underdeveloped area.
Transmission cost is independent of distance.
Higher bandwidth is available.
Larger coverage area than terrestrial network.
Independent from terrestrial infrastructure.

Disadvantages of Satellite Communication

Making and launching a satellite is a complex and costly process.
Difficulty in troubleshooting a satellite.
Larger propagation delay is found in satellite communication.

Major problems in satellite communication

Difficulty in designing and positioning a satellite.
Less stability (due to difficulty in alignment and direction of antenna).
Large power requirement.
Harsh climate affect transmission of signals.

Applications

Weather forecasting
VSAT(very small aperture terminal)
Communication
Military and intelligence satellite
Research and development
Observation of distant stars and other objects in space
GPS and navigation
