Amitec Satellite Communication Trainer STC24
Amitec Model STC24 Satellite Communication Lab 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 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 video
monitor provided with the system. Actual emulation of
satellite communication link can be performed with
emulation of path loss, propagation delay, noise, fading.
* Microwave operation
* Tele-command and telemetry facility
* Manchester encoding & CRC error checking
based PC-PC communication
* Emulation of signal fading, thermal noise
* Variable propagation delay.
* Variable path loss at two ends of uplink and
downlink channels
* High RF output power and low noise
* Digital display of PLL synthesized frequency
in Transmitter, Receiver and Satellite Emulator
* Condenser microphone and speaker provided
for audio link
* Camera and monitor provided for video link
* Satellite emulator has built-in antennas,
frequency transponder for communication link
* Helix (LHCP & RHCP), Yagi, Dish & Patch
antennas provided for linear & circular
polarization study
* Signal monitoring outputs at uplink & downlink
* C/N and S/N measurement facility
