INTRODUTION: An artificial body placed in orbit round the earth or another planet in order to collect information or for communication is known as "SATELLITE".
FOUR DIFFERENT TYPE OF SATELLITE ORBITS CAN BE IDENTIFIED,
HEO:- HIGHLY ELLIPTICAL ORBIT
DETAILED DESCRIPTION:-
GEOSTATIONARY EARTH ORBIT:
formula :- for calculating speed for orbit
![enter image description here][2]
ADVANTAGES:-
DISADVANTAGES:-
APPLICATION:- all tv & radio system
LOW EARTH ORBIT:
ADVANTAGES:-
DISADVANTAGES:-
1.SMALL COVERAGE-there is only small coverage of area 2.SHORTER LIFE-the life of antenna is shorter 3.COMPLEX ROUTING-as there is small range ,there is complex routing. 4.FREQUENT HANDOVER-there is frequently handover in the LEO
APPLICATION
They are used in globestar,iridium.
MEDIUM EARTH ORBIT:
ADVANTAGES
1.There is increased n coverage area.
2.there is simple design of antennA
3.fewer handovers
DISADVANTAGES
1.There is high transmission power due to increased coverage. 2.There is special need of special antenna 3.There is significant doppler effect.
APPLICATION:-
