Satellite communication involves the use of artificial satellites in orbit around Earth to facilitate communication between different points on the planet. These satellites receive signals from ground stations, amplify them, and then retransmit them back to Earth. This technology enables a wide range of applications, including television broadcasting, internet connectivity, and global positioning systems. Satellite communication is crucial for connecting remote locations, disaster relief efforts, and providing communication services in areas with limited infrastructure. However, challenges such as signal latency, signal interference, and high costs persist in satellite communication systems.
Satellites use a variety of imaging techniques, including visible light, infrared, and microwave imaging, to monitor weather patterns from space. These images help meteorologists track cloud cover, precipitation, temperature, and other weather features around the globe in almost real-time.
Indian satellites are launched primarily through the Indian Space Research Organization (ISRO) using its Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) rockets. These launches take place from the Satish Dhawan Space Centre in Sriharikota, India. Over the years, India has successfully launched a variety of satellites for communication, weather monitoring, navigation, and scientific purposes.
There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.
The main type of satellites are:
1) Geostationary
2) Polar
The name of the second satellite can vary depending on the context. It could be any specific satellite's name, such as "Hubble Space Telescope," "GPS satellite," or "ISS (International Space Station) satellite."
There is an orbit called a geosynchronous orbit (GEO), which is a satellite that travels around the Earth in the Earth's exact speed, so it's always in the same position as the Earth. GEOs are used for communication nowadays, and so ground stations are always in contact with the satellites. That means that your T.V. programs and phone calls are never interrupted! :D
A rocket has three parts all have tanks containing rocket fuel and oxygen. The first part lauches from earth than the secon part brings you closer the the targerted spot in space, The oxygen is needed because spase has no oxygen. Later the second part is released than the top containing the people is left with enough fuel to finish the job.
India has the best spy satellite...... Most people do not know this..........
i dont know. i dont even know what a moral issue is!
Generally unguided rockets used as weapons do not travel as far as missiles, which is the term for guided weapons. Rockets used as fireworks only travel a few hundred feet vertically. Model rockets may reach a height of a mile or more. Rockets used to launch satellites propel the payload above the atmosphere, which expends most of their fuel.
Because satellites lack the geographic constraints of terrestrial systems, they are better suited for long-distance, point-to-multipoint transmissions such as television broadcasts
