This document discusses satellite communication, including that satellites orbit large objects like planets, communication satellites transmit radio and television signals from space, and they can be thought of as microwave repeaters in the sky. It also outlines different types of satellite orbits (GEO, LEO, etc.), modulation techniques (ASK, FSK, PSK), multiple access methods (FDMA, TDMA, CDMA, WCDMA), applications (weather, broadcasting, navigation), and was submitted by 3 students for a communication electronics course.

1. • A satellite is an object
that orbits another large
object like planet.
• A communication
Satellite is a station in
space that is used for
telecommunication,
radio and television
signals.
• In Simplest form, a
satellite communication
can be thought of as
microwave repeater in
the sky.
i. Geostationary or
geosynchronous
earth orbit (GEO).
ii. Quasi-Zenith
Satellite.
iii. Low Earth Orbit
(LEO).
iv. Medium Earth Orbit
(MEO).
v. Highly Elliptical
Orbit (HEO).
Working:-
Modulation:
1. Amplitude Shift Keying
2. Frequency Shift Keying
3. Phase Shift Keying
Multiple Access Technique:
1. Frequency division Multiple Access
(FDMA).
2. Time Division Multiple Access
(TDMA).
3. Code Division Multiple Access
(CDMA).
4. Wideband Code Division Multiple
Access.
Application:-
1. Weather Forecasting.
2. Radio and TV
Broadcasting.
3. Military Application.
4. Navigation Application.
5. Connecting Remote
Areas.
6. Global Mobile
communication.
