|
Antenna Subsystems
|
the larger the satellite in space, the smaller the earth station, to be efficient the antenna should be designed to focus its signal on the location to which it transmits.
|
|

|
|
Parabolic dish design, principle of
|
the parabolic dish concentrates the power of the incoming signal on to one focal point
|
|
|
Low noise block converter (LNB)
|
sits at the focal point of the earth station and its main purpose is to amplify signals and suppress noise factors.
|
|
|
Footprint
|
the area of coverage within the satellite signal
|
|
|
Geosynchronous
|
operates at 22,300 miles above the earth's equator. The satellite rotates at the speed of the earth, hence it appears to be stationary.
|
|
|
Global Positioning Satellites (GPS)
|
the use of three satellites to eliminate possible locations to determine where you are.
|
|
|
Low Earth Orbiting Satellites (LEOs)
|
operate at 200 to 500 miles above earth, can capture detailed images of the earths surface for weather, geography.
|
|
|
Mobile Satellite Communication
|
involves using satellites for flexible transmission to moving vehicles or remote platforms
|
|
|
Point-to-Multipoint Distribution
|
term used in broadcasting, a satellite allows the transmission of a single signal to multiple receivers.
|
|
|
Polar Orbits
|
they have a circular orbit that takes them almost directly over the north and south pole. it scans continuously and therefore never sends a complete image.
|
|
|
Satellite communication advantages / limitations
|
economies of scale, provides wide area coverage, rapid installation of the ground network.
delay factor because a transmission takes a quarter second to complete, signal piracy a television signal can be intercepted by anyone equipped with a proper earth station. |
|
|
Satellite communication applications
|
