ISD Outline • • NCKU Review of Requirements Development Approach Software Development Status UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C. Ingraham 2
ISD Requirements • • NCKU Send Science Telemetry Receive Commands Send Command Status & SOH Receive PPS Receive Primary/Redundant Power Same Connectors as Flight Unit Same Protocols as Flight Unit UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C. Ingraham 3
ISD Development Approach • Engineering DPU – – – CPU PROM SRAM EEPROM Command & Status Channel Science Telemetry Channel • Engineering IDC (partial) • Breadboard Mass Memory (partial) NCKU UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C. Ingraham 4
ISD Software • Subset of Flight Software – Receives Commands • Acknowledges All Commands • Specific Response to Some Commands • Most Commands Are NOP – Sends SOH Products – Sends Canned Science Products – Receives PPS • Same I/O Protocols as for Flight NCKU UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C. Ingraham 5
ISD Interfaces • • • NCKU Science Telemetry (J 10) Command, Command Status, SOH (J 10) PPS (J 10) Power (J 8) Same Connectors as Flight Unit Same Protocols as Flight Unit UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C. Ingraham 6
ISD Development Status • DPU Functions working as on DPU BB • Baseline Functioning with GSE • Functions to be Implemented: – – MM Interface Power System Integration Power Simulation Command Response Simulation • All EEE Parts Selected • Most EEE Parts Ordered and Received NCKU UCB Tohoku IFR 5 -7 March 2001 Instrument Simulation Device C.
