Satellite Communication Uplink Transmitter

Satellite Communication Uplink Transmitter, Downlink Receiver and Transponder

Scientech 2272A Satellite Communication platform provides an indepth study of basic Satellite Communication system. It consists of Uplink Transmitter, Satellite Link and Downlink Receiver, which can be conveniently placed in the laboratory. The Satellite can be placed at an elevated, position if needed. The Satellite Transponder receives signal from Uplink Transmitter and retransmits at different frequencies to a Downlink Receiver. The Uplink and Downlink frequencies are selectable and can have variety of signals such as Video, Audio, Voice, Tone, Data and Telemetry (Temperature and Light intensity). The Operating manual illustrates basic theory and glossary of Satellite Communication terms along with Experiments.
