Satellite Communication Trainer (Model: IT-703)
The Satellite Communication Trainer IT-703 is a comprehensive educational system designed to demonstrate the fundamental principles and working concepts of satellite communication. It provides hands-on training by simulating real-world satellite communication links, making it ideal for engineering institutions, technical training centers, and research laboratories.
The trainer is structured into three fully integrated modules: Uplink Transmitter (IT-103A), Transponder (IT-703B), and Downlink Receiver (IT-703C). This modular design enables students to understand the complete communication process from signal transmission to reception through a satellite link.
The system supports simultaneous transmission of two audio channels and one video channel, allowing users to explore multi-channel communication. It is equipped with built-in generators, amplifier systems, and PC interfacing capabilities for advanced experimentation, including PC-to-PC data communication via satellite link.
