Good reconnaissance satellites or communication satellites investigation for military intelligence applications.
Weather satellites used to monitor the weather and climate of the world .. They provide continuous, up-to-date information about large-scale air conditions as the clouds and the temperature profile. Tiros 1, the first weather satellite which was launched in 1960.
