essay on human life enrichment on satellites
Answers
Answer:
Satellites are launched into the space to do a specific job, There are satellites that are launched to monitor the cloud patterns for the weather station, There are satellites that launched to send television signals for Sky TV, and every satellite has to be designed specifically to fulfill its function.
Satellites
Satellites are used for many things such as communication, oceanography, astronomy, the surveillance, They help many scientists get a perceptive view of all kinds of objects anywhere in the world.
Satellites send television signals directly to homes, They send the signals from a central station that generates programming to smaller stations that send the signals locally via the cables or the airwaves, The news broadcasts are sent from the field to the studio via the satellite.
Satellites offer the flight phone communications on the airplanes, They are the main conduit of voice communication for the rural areas and the areas where the phone lines are damaged after a disaster, And they provide the primary timing source for the cell phones and the pagers.

Communications satellites have the ability to rapidly communicate between a number of widely dispersed locations, They help the big manufacturing companies and the department stores to perform inventory management, They provide the instant credit card authorization and automated teller banking services to even small towns, They pay at the pump gas at the freeway gas stations, and video conferencing for the international corporations.
Astronomy satellites are the new technology that is mounted on earth-orbiting satellites or on the deep space probes, and they can give us an unobstructed view without the earth’s atmosphere interfering, They carry the detectors to record the electromagnetic radiation at wavelengths shorter than visible light.
Satellite-based navigation systems like Navstar Global Positioning Systems enable anyone with a handheld receiver to determine his location to within a few meters, They are known colloquially as GPS.
GPS locators are increasingly included in the car direction services, GPS based systems are used by the civilians and the military for navigation on land, the sea, and the air, and they are crucial in the situations like a ship making a difficult course in a harbor in the bad weather or the troops lost in unknown regions.
There are surveillance or spy satellites, There are four kinds of major satellites (White 100) which is the most commonly used, The reconnaissance use cameras to take the pictures of a particular place from up above, and they also have radar and infrared detectors, so, they can detect the things in the dark of the things that are covered by something or camouflage.
Reconnaissance satellites are used to spy on other countries, They provide intelligence information on the military activities of foreign countries, They can detect the missile launches or the nuclear explosions in space.
Reconnaissance satellites can pick up and record the radio and radar transmissions while passing over a country and they can be used as an orbital weapon by placing the warheads on a low orbit satellite to be launched at a ground target.
Ocean surveillance satellites are used to search for the ships or the submarines, They can spot the nuclear vessels, and new advancements may allow them to scan the depths of the ocean, Early warning and Elint satellites are primarily used by the armed forces, These basically protect the countries from the sneak attacks, and they can be used to detect if other countries are building or storing the nuclear warheads.
Elint is the basic spy satellite that picks up the radio transmissions, and the maps location of countries defense bases, It is the most important military satellite because it does not let another country to put together an attack without another country knowing.
Satellites today have a variety of uses. They are progressive and have enriched human life.
- Satellites in our routine lives possess many forms, applications, and uses. Technology for satellites has been developed to expand the use of active satellites to be used for various purposes
- Satellites help in various military and non military operations and also those serving the needs of humans to make life simpler and better.
- Satellites of communication encourage us to interact with individuals all over the world.
- To help forecast weather conditions, weather satellites help in observing the World from space.
- Satellite radio and television beam our favourite music albums, movies, and TV shows to Earth to enjoy.
- GPS is now a frequently used tool for global navigation and is useful for mapping, trading, land surveying, testing, tracking and surveillance applications.
