Communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Wireless communication uses electromagnetic waves to carry signals. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated points. To avoid signal interference, international organizations have regulations for which frequency bands certain organizations are allowed to use. This allocation of bands minimizes the risk of signal interference.

Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are "geostationary and "polar." A geostationary satellite travels from west to east over the equator.
Applications:
·         Fixed Service Satellite: FSS is the official classification for geostationary communications satellites used chiefly for broadcast feeds for television and radio stations and networks, as well as for telephony, data communications, and also for Direct-To-Home (DTH) cable and satellite TV channels.
·         Direct Broadcast Satellite: DBS is a term used to refer to satellite television broadcasts intended for home reception, also referred to as direct-to-home signals. It covers both analogue and digital television and radio reception, and is often extended to other services provided by modern digital television systems, including video-on-demand and interactive features. A "DBS service" usually refers to either a commercial service or a group of free channels available from one orbital position targeting one country.
·         Satellite Broadband: In recent years, satellite communication technology has been used as a means to connect to the internet via broadband data connections. This is very useful for users to test who are located in very remote areas, and can't access a wire line broadband or dialup connection.
Satellites are used for many purposes. There are weather satellitescommunications satellitesreconnaissance satellitesastronomy satellites and many other kinds. Arthur C. Clarke popularized the idea of the communications satellite. The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union on October 4, 1957.
Man-made satellites have several main uses:
·         Scientific Investigation
·         Earth observation - including weather forecasting and tracking storms and pollution
·         Communications - including satellite television and telephone calls
·         Navigation - including the Global Positioning System (GPS)
·         Military - including reconnaissance photography and communications (nuclear weapons are not allowed in space)

Electronic communication can take place in one-way or two-way transmission mode. One-way communication mode is a simple communication wherein a receiver lacks the ability to communicate back. The two-way communications may be half duplex or full duplex communication wherein a receiver can communicate with the transmitter. A Satellite communication is a technology that is used to transfer the signals from the transmitter to a receiver with the help of satellites. It can be used in different mobile applications that involve communication with the ships, vehicles and radio broadcasting services. The power and bandwidth of these satellites depend on the specifications like complexity, size and cost.

Earth observation satellites are satellites specifically designed for Earth observation from orbit. Most Earth observation satellites carry instruments that should be operated at a relatively low altitude, The Earth observation satellites ERS-1, ERS-2 and Envisat of European Space Agency as well as the MetOp spacecraft of EUMETSAT are all operated at altitudes of about 800 km. Spacecraft carrying instruments for which an altitude of 36000 km is suitable sometimes use a geostationary orbit. Such an orbit allows uninterrupted coverage of more than 1/3 of the Earth. Three geostationary spacecraft at longitudes separated with 120 degree can cover the whole Earth except the extreme Polar Regions. This type of orbit is mainly used for meteorological satellites.

Global positioning system is space based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more GPS satellite. Official name of GPS is navigational satellite timing and ranging global positioning system. GPS provides specially coded Satellite signals that can be processed with GPS receiver, enabling the receiver to compute position, velocity and time. A minimum of four GPS satellite  are require to compute positions in three dimensions and the time offset in the receiver clock. Accuracy and precision of data increases with more satellites.

Digital elevation model (DEM) is a digital model or 3D representation of a terrain's surface commonly for a planet (including Earth), moon, or asteroid created from terrain elevation data. The DEM could be acquired through techniques such as photogrammetry, lidar, IfSAR, land surveying, etc. DEMs are commonly built using data collected using remote sensing techniques, but they may also be built from land surveying. DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps. While a DSM may be useful for landscape modeling, city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies, geological applications, and other applications

Climate change is a change in average weather conditions. Climate change is caused by biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions .Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Weather warnings are important forecasts because they are used to protect life and property. However, satellite imagery can also undergo various types of quantitative processing to obtain information on important meteorological variables such as wind speed and direction, cloud height, surface temperature, sea ice cover, vegetation cover, precipitation, etc.

MEMS are made up of components between 1 and 100 micrometres in size (i.e. 0.001 to 0.1 mm), and MEMS devices generally range in size from 20 micrometres to a millimeter (i.e. 0.02 to 1.0 mm), although components arranged in arrays (e.g., digital micromirror devices) can be more than 1000mm2. They usually consist of a central unit that processes data (the microprocessor) and several components that interact with the surroundings such as micro sensors.
Applications:
· MEMS gyroscopes  used in modern cars and other applications to detect yaw; e.g., to deploy a roll over bar or trigger electronic stability control
· MEMS microphones in portable devices,e.g., mobile phones, headsets and laptops.The market for smart microphones includes smartphones, wearable devices, smart home and automotive applications
Inkjet printers, which use piezoelectrics or thermal bubble ejection to deposit ink on          paper.

 

Materials science in science fiction is the study of how materials science is portrayed in works of science fiction. The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no basis in science. Critical analysis of materials science in science fiction falls into the same general categories. The predictive aspects are emphasized, for example, in the motto of the Georgia Tech's department of materials science and engineering – Materials scientists lead the way in turning yesterday's science fiction into tomorrow's reality. This is also the theme of many technical articles, such as Material By Design: Future Science or Science Fiction? Found in IEEE Spectrum, the flagship magazine of Institute of Electrical and Electronics Engineers.

Initially available for broadcast to stationary TV receivers, popular mobile direct broadcast applications made their appearance with that arrival of two satellite radio systems: Sirius and XM Satellite Radio Holdings. Some manufacturers have also introduced special antennas for mobile reception of DBS television. Using GPS technology as a reference, these antennas automatically re-aim to the satellite no matter where or how the vehicle (that the antenna is mounted on) is situated. These mobile satellite antennas are popular with some recreational vehicle owners

Satellite broadcasting is the distribution of multimedia content or broadcast signals over or through a satellite network. The broadcast signals usually originate from a station such as a TV or radio station and then are sent via a satellite uplink (uploaded) to a geo-stationary artificial satellite for redistribution or retransmission to other predetermined geographic locations through an open or a secure channel. Downlinks are then received by base stations such as small home satellite dishes or by base stations owned by the local cable network for redistribution to their customers.
