    • First satellite  balloon with metal cover
    • The way of using
    • AT&T ECHO (1960)
    • ECHO II (1964)
    • Hovering in an low orbit
    • TELSTAR I (1962)
    • TELSTAR II (1963)
    • Successful transponders
    • Hovering in a low elliptical orbit
    • Two basic orbit:
    • Low orbit
    • Geostationary orbit
    • Benefits:
    • No use money
    • Don’t have to convert
    • Three satellites are enough
    • No change of frequency
    • Drawbacks:
    • Can’t reach polar region
    • Weak signals
    • SYNCOM II (1963)
    • Supported two signals at once (full-duplex)
    • INSTELSET I (first for commercial use)
    • INSTELSET III ( after this satellite was released the system
