Sci-tech Basic Satellite Communication Trainer Model TCM 006 is the first of its kind using actual techniques of satellite communication. It can uplink a given signal to a satellite link emulator, which can be stationed far away. The satellite will then re-transmit the same signal at a different frequency to a downlink station, which will receive the signal. Audio signal can be fed through a condenser microphone provided at Transmitter and reproduced on built-in loud-speaker at Receiver. Video signal can be sent from camera and viewed on a monitor. Actual emulation of satellite communication link can be performed with emulation of link fail, frequency translation.
