SATELLITE COMMUNICATION & BROADCATISTING
COMMUNICATION PROCESS
• COMMUNICATION-> PROCESS OF CONVEYING INFORMATION
• COMMUNICATION PROCESSES-> PROCESS OF ESTABLISH CONNECTION LINKS
• Eg-> -TELECOMMUNICATION
-RADAR COMMUNICATION
TYPES OF COMMUNICATION
• 1.-> LINE COMMUNICATION
• 2.-> WIRELESS COMMUNICATION
• SIGNAL
• A FUNCTION OF TIME, TEMPERATURE, PRESSURE etc.
• TYPES-> CONTINUOS TIME SIGNAL
DISCRETE TIME SIGNAL
SATELLITE COMMUNICATION
• SATELLITE-> A BODY WHICH REVOLVES AROUND A PLANET
• EARTH IS THAT PLANET
• KNOWN AS SATELLITE BECAUSE OF THE TIME PERIOD OF REVILVING IS 24H.
• COMUNICATION SATELLITE
ARTIFICIAL SATELLITE
• USED FOR TELECOMMUNICATION
• IT IS MODE OF COMMUNICATION OF SIGNAL B/W TRANSMITER & RECEIVER
• SATELLITE RELAY SYSTEM
• UPLINK & DOWN LINK
• UPLINK-> GROUND STATION FROM WHERE THE SIGNAL SEND TO SATELLITE
• DOWNLINK-> TRANSMITER END FROM SATELLITE WHERE THE SIGNAL IS SEND TO RECEIVING END ON EARTH
• ACTIVE & PASSIVE SATELLITE
• ACTIVE SATELITE-> INCLUDING TRANSMITER, RECEIVER, POWER SUPPLY & MICROWAVE REPEATERS
• PASSIVE SATELLITE-> THESE ARE NOTING JUST LIKE A METAL REFLECTOR
HOW SATELLITE WORK
SATELLITE ELEVATION
• LEO
480 MILESABOVE FROM EARTH
FREQ. 1G Hz to 2.5 G Hz
• MEO
FREQ. 1.2G Hz TO 1.66G Hz ORBIT IS B/W 6000 MILES & 12000 MILES
• GEO
FREQ. 2G Hz TO 18G Hz
ORBIT 22300 MILES ABOVE EARTH SURFACE
ANTENNA LOOK ANGLE
• USED FOR MAXIMUM GAIN OF EARTH STATION
• ANGLE OF ELEVATION
• AZIMUTHAL ANGLE
TYPEOF COMMUNICATION
• UNICAST -> WHEN ONE COMPUTERIS CONNECTED TO ANOTHER
• BROADCAST-> ON COMPUTER IS CONNECTED TO MANY COMPUTER
• BROADCASTING
• DISTRIBUTION OF AUDIO & VIDEO SIGNAL
TYPES:
- RECORDED BROADCASTING
- LIVE BROADCASTING
• ANTENNA
• BASICALLY IT IS ELECTRONIC EAR , EYE & MOUTH
• DEVICE WHICH IS USED AS TRANSMITING AS WELL AS RECEIVING PURPOSE
PARABOLIC ANTENNA
• ->HIGH GAIN REFLECTOR ANTENNA
• ->USED IN
• TV COMMUNICATION
• RADIO COMMUNICATION
• DATA COMMUNICATION
WORKING OF PARABOLIC ANTENNA
• TELEPORT
• COMPLETE SOLUTION FOR BROADCAT & SATELLITE NETWORKS
• IT IS SIGNATURE FOR A BROADCAST
• BY IT WE COVER ALL PRESTIGIOUS LIVE EVENTS
• WORKING OF TELEPORT
