Descrição Geral

The Satellite Unit, "ESA", is an advanced system that operates in conjunction with a computer (PC), which allows students an easy way to manage and visualize the data. The "ESA" software allows to perform multiple actions: configuring the sending data, selecting the desired test point to visualize, selecting different faults in the unit, etc.

The Satellite Unit, "ESA", is divided into different modules to allow the student a better understanding of the unit. These modules are: Satellite Ground Transmitter Station, Satellite Ground Receiver Station, Satellite Repeater and the Control Signal and Data Acquisition Module.

The Satellite Ground Transmitter Station works as a real ground based unit, transmitting the signal (uplink) to the Satellite Repeater through the Satellite Ground Transmitter Antenna. The Satellite Ground Receiver Station works as a real ground based unit, receiving the signal (downlink) from the Satellite Repeater through the Satellite Ground Receiver Antenna. Both, Transmitter and Receiver, are connected to the computer for signal analysis, configuring the data transmission, data visualization, etc.

The Satellite Repeater Module works as real active satellite repeater. It includes a processing system that amplifies the incoming signal from the Satellite Ground Transmitter Station (uplink) through the Satellite Receiver Antenna, and emits the processed signal in a different band of frequencies (downlink) through the Satellite Transmitter Antenna.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Signals and Data Acquisition Module + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
