The Satellites History of development has of course political beginning, as a new coming technology with great possibilities, satellites technology had to find interest in political leaders minds at first and than to appear in hands of military sources. Here keeping and showing power played the leading role in pushing the progress and outer space turned to be a new battlefield.
Not so long ago, satellites were exotic, top-secret devices. They were used primarily in a military capacity, for activities such as navigation and espionage.

On the picture are seen overlapping footprints of four different satellites. If you wanted to send a signal from Africa to Southeast Asia, you could bounce, or relay, the signal using more than one satellite.
A brief look at the international space community, technology trends and opportunities shows the great prospective of this technology, policy and economic trends connected with it and impressive commercially viable space applications of the future.
