Estaunie, an engineer & novelist.
Combination of Greek prefix ‘tele’ meaning
‘far off’ & Latin word ‘Communicare’
meaning ‘to share’.
14. COMMUNICATION stands for

33. CONCEPT OF SATELLITE
COMMUNICATION
Satellite is a solid object
which revolves around some heavenly
body
due to the effect of mutual gravitational
forces.
35. It is the communication of satellites in
space with large number of earth stations
on the ground.
36. A Communication Satellite is a
Microwave relay station placed in outer
space.
These satellites are launched either by
rockets or by the space shutters.
These are positioned 36000 Kms. Above
the equator with an orbit speed that
matches the earth’s rotation speed.
38. Introduced the idea of
Satellite Communication.
He stated: “ If a satellite
were positioned high
enough above the
equator & its speed was
1945, Arthur Clarke
controlled to match that of earth’s rotation,
it would appear stationary in its geostationary
orbit in the sky.
39. EARLIER TIMES
LARGE SIZED ANTENAES were used
because of the receipt of very weak
signals.
40. PRESENT TIMES
Satellites have become
stronger
Bigger &
More powerful therefore antennas used
have become automatically smaller in
size.
42. ACTIVE SATELLITES
Active Satellites:
Complicated in structures.
Processing equipment: Transponders,
which plays important role in the
functioning of the Satellite.
Transponder provides amplification of the
incoming signal.
It is also useful in avoiding interference
between the two signals.
43. PASSIVE SATELLITES
These are relay stations in space.
These are sub-divided in 2 categories:
1. Natural Satellites: eg. The Moon.
2. Artificial satellites: eg. Rohini, Spherical
balloon with metal coated plastic.

47. BASICS:
TERMS & VOCABULARY
1. Satellite Channels: Every satellite has 4
transponders/channels. Each of these
channels can transmit one TV signal or
thousands of simultaneous calls.
2. High Frequency Band: Satellite signals use
C-band & KU-band.
52. KU-BAND
The new generation of satellite is now
using a bit higher frequency ranging from
11.7 to 12.3 GHz.
53.
54. SATELLITE DISH
It is primarily an antenna that selects &
focuses the satellite signal
55.
56. SATELLITE ANTENNA
Also known as a ‘footprint’ directs its
signals to all destined reception areas on
the ground in a particular shape.
The signal is strongest at the centre of that
area which makes it possible to use
smaller dishes from reception.
As one moves from the center, the signal
diminishes in intensity, therefore large
dishes are needed.
57.
58. UPLINK & DOWNLINK
UPLINK:
It is a ground station that sends signal up to
the satellite.
DOWNLINK:
The satellite changes the signal’s frequency &
transmits it to downlinks.
