One of the most important inventions of humanity in the 20th century is the satellite, which is the fruit of many years of great efforts and the culmination of the technological advancement of mankind. With the development of satellites set in the orbit of the earth, it became possible to conduct high-altitude imagery, independent of political boundaries. The development of electronic systems for the production of images and other imaging techniques, such as radar and infrared images, have caused many changes in remote sensing. Today, satellites provide experts with a wealth of various information about the planet. Today's age is called the Space Age, because spatial information is an integral part of today's life. Now the Space Contest is entering a new stage in order to gain information supremacy, and almost all countries that have enjoyed the taste of utilization of ultra-atmospheric space have been encouraged to build satellites with less expensive capabilities, and countries that do not benefit from this blessing have also made the achievement of this complex human-made phenomenon a priority.
