Earth observation satellites (EOS) are orbital devices specially designed for monitoring and monitoring the Earth to achieve an enriched understanding of layers and the Earth system. Basically, EOS are grouped into synchronized series of polar-orbiting satellites for continuous observation work of the land, water surface, atmosphere and biosphere. EOS operate at low altitudes (around 800 km) to obtain a better picture of designated targets.1.2 HistoryThe first spark for innovation in observation satellites occurred during World War I, where aircraft were used to scan enemy areas using basic cameras. This progressed further during World War II as aerial photos were invented for mapping purposes. Subsequently, image processing was enriched with digital chorological matrix systems to produce better quality data. In fact, on October 4, 1957, the Soviet Union launched the first satellite into space. This created a competitive market for the United States and a real threat, as they called it a "missile gap." A year later, the US Department of Defense launched Explorer 1 on January 31. competition led technologies to continue to become more sophisticated when civilian satellites appeared on the market, such as weather observation satellites (METEOSAT and NOAA)[1]. In fact, the first meteorological satellite was launched by NASA in 1960 (TRIOS 1) and the first rotationally stabilized communications satellite in 1966. The awareness that these satellites created for civilization has been well recognized by all researchers and scientists to develop and improve technology to meet human needs in all aspects of life. In fact, since 1982, NOAA satellites have helped...... middle of paper ......a wide variety of chemical limitsV. Very sensitiveVI. No spectrum regulationVII. Low energy consumptionVIII.
