Electrical Ground Support Equipment (EGSE)

The same test equipment is used during all program phases: unit level electrical tests, system level electrical tests, and flight operations. The EGSE hardware architecture is based on a modular design. The different subsystems are connected via a standard internal bus (32-bit PCI). The main components are:

• a Microprocessor System (Pentium II PC for commanding, data decoding, data display, etc.),
• a dual S/C OBDH interface simulator, 
• three sensor electronics simulators, and 
• a primary power supply unit.

External PCs can be connected to the EGSE via a private network (Ethernet) for remote data analysis and instrument control.
