1. ESA GSE

2. Power / Thermal / Mechanical
Provide regulated voltages
Facilitate current measurements
Mechanical
6U VME support (without Wedge-locks)
Portable and Rugged for transport
Open rack for access while under test
Connectors are acceptable for flight interconnection

3. Electrical Interface Mechanical interface to signals
Before DCB & ETC, GSE connector as defined for ESA-to-IDPU
Afterwards data is taken through DCB connector.
Analog Housekeeping
One MUXed analog housekeeping value
Electrical Quality
GSE Interface circuitry must be flight grade

4. Command and Telemetry Handling
Commands (when DCB & ETC present)
Sends CDI 24-bit commands per ICD specification
User command interface in STOL
Reads STOL command files
Compatible format with IDPU GSE and MOC GSE
Commands (before DCB) are CDI
Telemetry
Before DCB & ETC, data is taken directly by GSE h/w
Afterwards data is extracted from packet telemetry.

5. Data Manipulation and Display
Calibration software (per FAST).
Input data or outputs from calculations can be displayed, saved to disk, and/or plotted with library routines.
Convenient access to data for offline processing (FTP, HTTP, etc.)
Supports “screen print” capability

6. Errors and Responses
GSE software monitors serial instrument data stream for missing or corrupted data. All detected anomalies are logged, counted, and displayed in user interface.

7. Mission Requirements Compatibility with next level integration
Uses ITOS, LabWindows, C
PC standards (same platform through all mission phases)
