Description

SCOPE OF LEARNING:

• The Satellite Communication Lab provides an in-depth look at Satellite Communication Techniques and Concepts. It consists of Satellite Uplink Transmitter, Satellite Transponder Link and Satellite Downlink Receiver, which can be conveniently placed in the laboratory for experimentation. The Satellite Transponder Link also called as Satellite Emulator can also be placed at an elevated position if needed. The satellite transponder receives signals from uplink transmitter and retransmits at different frequencies to a downlink receiver. The uplink frequencies are selectable and can carry three signals video/data, audio/voice/tone (A1) and audio/voice/tone (A2) simultaneously. Any broadband signal or digital / analog data or square wave from function generator can be transmitted through this satellite link. A large number of experiments can easily be conducted. PC to PC Communication Link can also be established & studied.
