Satellite Communication Trainer ST-2400 is a low cost high performance Satellite Communication training system. It is designed for teaching and demonstrating basic Satellite Communication techniques and concepts for Technical Colleges and Engineering Universities for undergraduate and graduate courses.
ST-2400 can be conveniently placed in the laboratory. It can be placed at an elevation position if needed. The Satellite Transponder receives signal from Uplink Transmitter and retransmit at different frequency to a Downlink Receiver. The Uplink and Downlink frequencies can carry three signals i.e. Video, Audio and Data simultaneously. Any broadband signal or Digital/Analog data or function generator waveforms can be transmitted through this Satellite link. A large number of experiments can be conducted very easily on this Trainer.
