Satellite Communications Training System

Description

The Satellite Communications Training System is a versatile telecommunications training platform designed to teach modern telecommunications technologies in the classroom using a fully operational satellite link. The transmitter, receiver, and satellite repeater operate at realistic uplink and downlink frequencies and at safe power levels.

The system allows students to observe and study a wide range of telecommunications concepts such as digital and analog modulation, scrambling, differential encoding, and frequency conversion as well as concepts specifically related to satellite communications. In addition, since noise and losses affect the performance of all telecommunications systems, performance-related concepts such as noise figure, figure of merit, link budget, and the performance ratio C/N0 are also covered.

The Earth Station Transmitter performs analog (wideband FM) or digital (DQPSK) modulation of the baseband signal, then transmits the upconverted uplink signal to the Satellite Repeater. The Satellite Repeater is a transparent repeater that shifts the uplink signal to a lower frequency, amplifies it, and then retransmits it as the downlink signal. The Earth Station Receiver downconverts and demodulates the downlink signal to recover the baseband signal. The Earth Station Transmitter and the Earth Station Receiver can be placed on the same table for easy connection to instruments, as shown in the photo above, or can be physically separated.

Features & Benefits

  • Provides hands-on, system-level training in telecommunications and satellite communications technologies.
  • Realistic system reflecting the standards and modulation types used in modern satellite communications systems.
  • Uses license-free transmission and low power levels for complete safety.
  • Can be interfaced with external analog or digital equipment.
  • Fault-insertion capability in the Earth Station Transmitter, Earth Station Receiver, and Satellite Repeater (via telemetry) allows the teaching of troubleshooting.
  • Comprehensive courseware provides theory and step-by-step laboratory procedures.
  • Includes both analog and digital modulators/demodulators to provide an analog or digital link from transmitter to repeater to receiver.
  • The analog link uses Wideband FM Modulation allowing transmission and reception of analog (e.g. audio or video) signals. The 10 MHz bandwidth is sufficient for transmission of composite video or multiplexed (FDM) signals from external equipment.
  • The digital link allows data rates up to 20 Mbit/s and includes a built-in 4-channel TDM multiplexer and demultiplexer. On the transmitter and the receiver, three TDM channels have BNC connectors; one channel has a USB port for data transfer with a computer running the Data Transfer applications.
  • The Data Transfer applications allow transmission of files, text messages and real-time data over the satellite link.
  • The Orbit Simulator software provides interactive visualization of satellite orbital mechanics and satellite coverage and illustrates the theory behind antenna alignment with geostationary satellites.
  • The Telemetry and Instrumentation Add-On provides waveform and data generation, data acquisition, virtual instruments, and telemetry with the Satellite Repeater.
  • Telemetry capabilities include remote power measurement, gain control, and redundancy switching, as well as remote fault insertion and diagnostics for troubleshooting the Satellite Repeater.
  • Optional Telemetry and Instrumentation Add-On is an economical alternative to expensive, high-frequency conventional instruments
  • Can expand and complete existing telecommunication programs (radar, antenna, microwave, etc.)
  • With the horn antennas included, the maximum transmission distance (between the transmitter or receiver and the repeater) is at least 4 m (13 ft).

Note: When performing data transfer using one computer, the data sent from the computer is transmitted over the satellite link and received by the same computer. The Data Transfer software allows using two computers, a sending computer connected to the Earth Station Transmitter and a receiving computer connected to the Earth Station Receiver.
