Detailed explanation-1: -Passive Satellites: Satellites that just reflect the signal back towards the Earth without amplification.
Detailed explanation-2: -Last week, the Museum recognized the 50th anniversary of Telstar, the first “active” satellite (one that can receive a radio signal from a ground station and then immediately re-transmit it to another) and the first technology of any kind that enabled transatlantic television transmissions.
Detailed explanation-3: -Pierce’s team at Bell Labs also developed Telstar 1, the first active communications satellite capable of two-way communications. Telstar 1 was launched into low Earth orbit on July 10, 1962, by a Delta rocket. NASA provided the launch services and some tracking and telemetry support.
Detailed explanation-4: -A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder-an integrated receiver and transmitter of radio signals.
