ESA GSE

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

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

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.

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

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.

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