  • Essay / Satellites and their potential

    Satellites are man-made objects or instruments mounted in space to facilitate the collection of information for various purposes such as communications, mapping, disasters , among others, and generally orbit the Earth as well as other planets. There are two different types of satellites: natural and artificial. The very first satellite referring to Sputnik was launched on October 4, 1957 by the Union of Soviet Socialist Republics, commonly known as the USSR, to collect various information about scientific events.

However, further research needs to be undertaken to help strengthen the use of artificial satellites, as outlined in this paper. Artificial or artificial satellites, revolving around the Earth, have been used in various fields such as surveillance, communication, weather forecasting and disaster management, GPS tracking, remote sensing which have guided various developments on Earth. Before the invention of satellites by early scientists, this information or data was collected using physical observations which had several limitations. However, since the inventions, particularly in recent decades, more powerful sensors have been developed with advanced capabilities for recovery, processing and transfers, particularly geophysical studies. Satellites have the ability to observe and cover large areas of the Earth at the same time, meaning they collect and transfer data faster than ground-based instruments. Since they are mounted above clouds and other obstacles, they provide excellent and expansive views, much better than ground-based telescopes. Initially, television signals could not travel long distances since they moved in straight lines and therefore could be blocked by tall buildings, trees or even end up disappearing into space. Telephone communication was also a big problem, because installing telecommunication cables underwater or above ground was too expensive and time-consuming. But with the introduction of satellites, telephone and television signals are instantly transferred into space and instantly retransmitted to the ground at various locations on Earth. Most modern satellites consist of two parts: antennas to send and receive signals, and a power source, such as a battery or solar power, to enable operations. Some also have scientific cameras and sensors pointed at the Earth's surface to extract information about water, land and air. At times, in order to gather information about the universe and the solar system, they face space. A fascinating fact is that satellites never collide with each other because they are placed in well-designed orbits to avoid each other, as well as NASA and other observatories. bodies, keep their traces. There are several technologies or data applications that can be used to enhance the potential for satellite use, for example in Egypt (Mohammed Shokr 2011), recommends both a horizontal approach involving widening application ranges using more powerful sensors and stimulating the synergy of data from.
