January 2012: Innovative Spacewire-based harness-reduction technique for the LOFT CDF study
 
TEC-EDD provided expertise for the definition of the Data Handling System (DHS), based on some initial mission requirements. The main elements of the DHS were the on-board computer (OBC), including the processor modules (PM), the telemetry/telecommand (TM/TC) modules, the reconfiguration module (RM), the I/O modules and power supplies. There were also dedicated Instrument Controller Unit for each instrument. These PDHUs are responsible for interfacing the instruments to their local mass memory units and to the OBC, but also for configuring the instruments and collecting housekeeping data. In addition the Instrument Controller Units support science data compression and processing, e.g. image compression (in the case of the WFM instrument).

December 2011: Test campaign on LVDS
 
In 2011, the Onboard Computer and Data Handling section has performed a lab test campaign on LVDS components in order to characterize them in a cross-strapping configuration used in On Board Computer units. LVDS drivers (’31) and receivers (’32) from three different manufactures (National Semiconductor, STm and Aeroflex) have been tested.
