Ground Support Equipment Concept (GSE) Werner Magnes Institut für Weltraumforschung (IWF) Austrian Academy of Sciences FGM peer CDR GSE - 1 Berlin, April 6, 2004

GSE Concept MGSE for FGS • Mu-metal can EGSE for FGE commanding and testing • • FGM peer CDR Digital interface simulator (bread board EGSE) with limited features for bread board testing (supplied by IWF) Full functional EGSE for ETU and FM (supplied by UCB) GSE - 2 Berlin, April 6, 2004

Mu-Metal Can System Integration 60 62 FGM MGSE which can be put over the sensor Shielding factor of 10 -50 FGM peer CDR GSE - 3 Berlin, April 6, 2004

Digital I/F Simulator Only bread board testing FGM peer CDR GSE - 4 Berlin, April 6, 2004

Power / Thermal / Mechanical Power • • • Compatible with power plugs in Germany Provide regulated voltages Allows current measurements to verify power of FGE circuitry Mechanical • • 6 U VME support (without Wedge-locks) for FGE Portable and rugged for transport to Europe Open rack for access while under test Connectors are acceptable for flight interconnection FGM peer CDR GSE - 5 Berlin, April 6, 2004

Command & Telemetry Handling Commands • Sends CDI 24 -bit commands per ICD specification • User format in ITOS • Reads ITOS format command files • Compatible format with IDPU GSE and MOC GSE Telemetry • Records high resolution (128 Hz vectors) • Records low resolution (4 -128 Hz vectors) Storage • Stores vectors to disk in ASCII format X Y Z with spaces between • Optional time/temp Format: Time Temp 1 Temp 2 X Y Z FGM peer CDR GSE - 6 Berlin, April 6, 2004

Data Plotting & Display • Plots one second of the 128 Hz data (X, Y , Z) with an update of every second • Plots the low resolution data (X, Y, Z) in a variable length (e. g. 30 second) long window • Plots one second mean values (Xm, Ym, Zm) as well as the standard deviation (Xsd, Ysd, Zsd) of 128 vectors of the 128 Hz data with an update every second • Numeric Displays of Xm, Ym, Zm • Supports “screen print” capability FGM peer CDR GSE - 7 Berlin, April 6, 2004

EGSE Error Checking and Response • None identified Mission Requirements • • Compatible with TU-BS/IWF Systems (TBD) Network for data transfer Compatibility with next level integration • • Uses ITOS, Lab. Windows, C PC standards FGM peer CDR GSE - 8 Berlin, April 6, 2004
