Satellite Communication Training System 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 up to 100 feet away. The emulator then re-transmits the same signal at a different frequency to a downlink receiver signal. Audio signal can be fed through a microphone provided at Transmitter and reproduced on built-in loud-speaker at Receiver. Video signal can be sent from CCD camera and viewed on a video monitor provided with the system. External broadband digital or analog data can be used for link testing. The system provides facility to interface with communication trainer kits. Actual emulation of satellite communication link can be performed with emulation of path loss, propagation delay, noise, fading, etc. Interactive user-friendly e-Manual software is provided with this training system on CD.
