Among the earliest examples is Sputnik 1, launched in 1957, which is considered the starting point of this technological lineage due to its mass being close to that of modern microsatellites.Mantzouris, G. “Micro and Pico Sat

Military satellite systems are advanced space platforms that provide highly secure and continuous communication links between the Earth and space, serving national security, defense capabilities, and strategic intelligence operations. These systems are employed in critical functions such as communications, reconnaissance, target acquisition, early warning, and positioning, becoming an indispensable component of modern military command and control infrastructure.
