4. Timothy Edward Quinn FIELDS iPDR – GSE Components 4 Ground Support Equipment Operating System (GSEOS) –Telemetry and command control –GSE control (Power supplies, stimulus, etc.) –Supplied by project –Extensive in-house knowledge (RBSP, MAVEN) Python scripting interface for closed loop instrument control Fields Instrument GSE (FIG) –Simulate DCB/TDS and Instrument interfaces –Adapted from MAVEN Instrument Simulator GSE (MISG) Spacecraft Emulator (SCE) –Supplied by project Power supplies, signal generators, network router, etc. Overview

5. Timothy Edward Quinn FIELDS iPDR – GSE Components 5 –ZestET1 off-the-shelf module High-speed Ethernet (TCP/IP Offload) engine (TOE) Configurable (Xilinx) FPGA – Instrument/DCB/TDS interfaces, along with the data flow and control are implemented in the FPGA, which interacts with the TOE to transfer data to/from the GSEOS –Base (Interface) Board connects to the Zest-ET1 FPGA Provides buffers and connectors that match the Fields DCB/TDS flight configuration –Whenever possible, the FIG uses the actual flight design, assuring that the simulated interfaces match the flight hardware (The interface between the DCB/TDS and Instruments is a clocked serial bit-stream) –Communicates with GSEOS via TCP/IP. Fields Instrument GSE (FIG)

6. Timothy Edward Quinn FIELDS iPDR – GSE Components 6 –DCB/TDS test interface for instrument bench level testing Sends commands to and receives telemetry from the Instrument under test Provides an independent but synchronous “high-speed” (38.4/19.2 MHz) clock for those instruments that require it and a power-supply synch signal –Instrument test interface for DCB/TDS testing FIG receives commands from and sends telemetry to the DCB/TDS under test Simulated instruments include MAG, DFB, TDS, and SWEAP instruments FIG telemetry production is impartial with respect to the instruments; each of the four possible instrument outputs is personalized via its loaded pattern and operates synchronously to its own dedicated clock supplied by the DCB/TDS. (In practice, these clocks are 4.8MHz, derived from the DCB/TDS Master clock.) Fields Instrument GSE (FIG)
