1 General Description
The ASPERA 3 EGSE consists of two IBM-PC class computers running Linux operating system. The
first PC hosts two programs modules linked via standard TCP/IP socket:
• The “Instrument Level Test” module (MEXILT) to be used only at instrument level test
• The “Command and Display Module (SCOE) to be used both at instrument and system level
test.
The second PC, hosting the “science Display Module” (SDM), is connected via NFS to the SCOE, and
is responsible for science display of the telemetry data archived by the SCOE.
The EGSE block diagram is shown in the following figure.
