The July 2004 FSW Demonstration focuses on inter-task communications between real FSW tasks running on an SIU on the FSW Testbed. In May, the FSW Team demonstrated ITC, using simple test-code tasks to receive ITC messages. This month, ITC is used to interconnect FSW tasks through commands and telemetry -- in this case, it connects the CTDB (1553 communications) and LHK (Housekeeping) systems.

As in the June demonstration, the Spacecraft is represented by the Spacecraft Data Interface Simulator (SDIS), a high-fidelity Spacecraft simulator provided by Spectrum Astro, Inc. The LAT is represented by the FSW Testbed, which currently provides a large collection of flight-like data acquisition hardware, including a flight-like SIU, a complete GASU, PDU, and multiple TEMs.
