Effects of Solar Activities on Remote Sensing and Telecommunication Satellites' Operations

Today, thousands of satellites revolve around the Earth with diverse aims, and each of these satellites is at a certain distance from the Earth depending on the purpose it pursues. Satellite plays an important role in scientific research and communication, and it might be said that these satellites have made the Global Village a reality, and thus play a crucial role in present-day civilization. Contrary to common ideas about ​​satellites, they are not immune from effects of environmental factors in their surroundings, and are indeed influenced by factors such as the Sun and solar activities and other atmospheric influences, including the coronal material of the sun, solar flares and .... In this paper, we intend to briefly describe some of the factors producing disorder in the work of satellites or affecting their life-span. Among the strengths of the paper is the up-to-date quality of most of content, including the fact that most of these materials have been discovered in recent decades, and we have obtained them from the latest Internet websites and articles.
