Advantages of artificial satellite

Satellites provide invaluable services to society. They have brought together people from different continents by providing an instantaneous link through satellite telephone and television signals. Another important application of satellites, perhaps one we think less about, is the continuous monitoring of the global environment. Recently, the world has seen shocking pictures of the BP oil spill from Yet, as this article will illustrate, the range of environmental uses for satellites goes far beyond weather forecasting and human-made disaster monitoring. Evolution and types of satellites Satellites have come a long way since the Soviet Union launched Sputnik 1, the first ever The Sputnik 1 launch elicited interesting reactions, most of which turned out to be wrong. At the time, military experts said that satellites would have no practical application in the foreseeable future. On 1 April 1960, the US launched TIROS-1, the world’s first weather satellite. It spent only 78 days in orbit, but its impact endures today. [quote quote=”From 1960 on, there have been continuous improvements in instruments and technology and the number of uses for satellite data has also increased.” type=”image” image=”2208″ ] “This satellite forever changed weather forecasting,” says Dr. Jane Lubchenco, Administrator of the US National Oceanic and Atmospheric Administration (NOAA). TIROS-1 had very limited capabilities: two cameras and two video recorders. But from 1960 on, there have been continuo...

Advantages and Disadvantages of Satellite Communication We occasionally see some intriguing lights travelling gradually and in a linear fashion through the night sky without blinking or sparkling. It could be a satellite. There are many distinct sorts of satellites that orbit or travel around a planet or star. The moon is an innate example of a satellite in view of the fact that it spins around the Earth. However, in most instances, when individuals refer to satellites, they refer to manufactured objects sent into orbit. Satellites orbit the Earth like spacecraft and are typically equipped with a computer and solar panels that draw power from the Sun. In 1957, a satellite was launched into orbit for the first time. It was named as Sputnik and was roughly the size of a ball. Tons of satellites are currently present in the sky. They occasionally also have cameras or other research gear to aid data collection. Let's examine in greater detail what satellite communication is, how they operate, what they are employed for, and their benefits and drawbacks in this post. Satellite Communication System What is a Satellite? Any entity that orbits a planet in a curved route is considered a satellite. Another way to think of a satellite is as a tiny object in space that orbits a bigger one. Classification of Satellites When it comes to categorizing satellites, there are two main categories: • Natural Satellite Natural satellites are natural objects that orbit other, larger natural obje...

On October 4, 1957, the Soviet Union inaugurated the "Space Age" by sending the first artificial satellite to space called Sputnik. According to , the name is derived from the Russian word for "space traveler." Over 60 years later, various sizes and types of satellites are now already in orbit. Scientists have also innovated into making smaller satellites called nanosatellites, which are believed to be the future of satellites to deliver information on Earth's ionosphere. Nanosatellites vs. Conventional Satellites According to One of the advantages of nanosatellites is their size and cost. Since they are smaller than the conventional satellite, they are cheaper to make. A conventional satellite with an average size could cost more than US$575 million, whereas an average nanosatellite can only cost around US$575,000 to launch. Moreover, conventional satellites have individual designs and custom-built parts. However, nanosatellites have similar set designs and use "off-the-shelf" commercially available parts. They can be reproduced in a shorter time and can be launched from a standardized Nanosatellite Launch Vehicle ((NLV). Spanish company , which designs, constructs, and develops nanosatellites, shared on their website that telecommunications technologies are constantly changing and updating, but it is hard to constantly update large satellites. Unlike large conventional satellites, nanosatellites only take about eight months to develop. More so, nanosatellite constellatio...

Satellites, Non-Governmental High Resolution High-resolution satellites, generally understood to be those with a spatial resolution of 2 meters (6.6 feet) or less, have the capability to provide forensic information from areas that are otherwise inaccessible to law enforcement officials. Resolution is a measure of the ability of an image to depict detail. When used in reference to digital images such as those produced by remote sensing satellites, resolution generally refers to size of the pixels, or fundamental elements, comprising the image. A 2-meter resolution image consists of elements representing the average color or intensity of a 2x2 meter area of The best commercial satellites operating in 2005 had resolutions of 1 meter (3.3 feet) or less. However, intelligence satellites operated by the U.S. government were believed to have a resolution of about 2 centimeters (0.8 inches). Images with that resolution, however, have never been released for public use. The first remote sensing satellites were built, launched, and operated by government agencies in the 1960s. In the interest of national security, images from these satellites were tightly controlled and generally inaccessible to civilian officials and forensic scientists. Imagery from the first Landsat satellites, launched by the The Landsat and SPOT satellites paved the way for a new generation of high-resolution commercial satellites that provide images detailed enough for forensic work. The commercial IKONOS sat...
