23 rd October 2009 Stuart Fowell SciSys and Astrium SOIS Projects - CCSDS Fall 2009 Meeting

2 SciSys & Astrium SOIS Projects Outcome of SOIS Reference Implementation Prior Project ESA TRP project , SciSys and EADS Astrium Developed initial prototype of SOIS services, demonstrated on ESA RASTA facility SOIS ICD (= API) SOIS Application Support Services All but File Transfer and Packet Store Services SpaceWire Subnetwork Services All but Test Service Bespoke Packet Service MIL-STD-1553B Subnetwork Services All services, using subset of ECSS 1553 services SOIS Demonstrator Showing use of SOIS in a dummy Reference Mission Provided feedback: On draft SOIS standards On proposed upgrades and optimisations to software and RASTA Facility

3 SciSys & Astrium SOIS Projects SOIS and ECSS Standards Since Ongoing standardisation process SOIS Subnetwork Services to be published No technical changes SOIS Application Support Services ongoing Small refinements to all services SOIS Plug-and-Play NASA-led investigations into the use of Electronic Data Sheets to support Plug-and-Play & Device Virtualisation ECSS 1553 standard has been published ECSS SpaceWire WG: CCSDS Packet Transfer Protocol defined SpaceWire-T emerging from SpaceNet GSTP project ECSS CAN WG The changes that have occurred to the SOIS standards since we froze them for the SOIS Reference Implementation project + the expected changes over the next 3-6 months

4 SciSys & Astrium SOIS Projects SOIS Proof of Concept Project – Objectives & Scope ESA TRP project , SciSys and EADS Astrium Standardisation of SOIS APIs Implementation of all SOIS services, running over SpaceWire and MIL- STD-1553B Inc. mapping onto ECSS-E-ST-50-13C for MIL-STD-1553B (BC and RT) Optimise and characterise implementation of SOIS services on RASTA Towards definition of Communication Management and Service MIBs Integrate SOIS services with other Avionics Components TM/TC Modules and Ground Units, PUS, CFDP SpaceWire-based Advanced Mass Memory & File Store Legacy MIL-STD-1553B Remote Terminal Units Prototype use of Electronic Data Sheets for SOIS Plug-and-Play SOIS Demonstrator Feedback to CCSDS

5 SciSys & Astrium SOIS Projects RASTA Test Facility Reference Avionics System Test-bench Activity (RASTA) RASTA OBC supplied by Aeroflex Gaisler LEON2 ASIC (100 ESA or LEON3 FPGA (40 SciSys 3 x SpaceWire links 2 x MIL-STD-1553B BC, RT or BM + others (CAN, Ethernet, UART and Direct I/O) RTEMS drivers STARDundee USB-SpaceWire Router & Linux PCs PCI MIL-STD-1553B cards & Linux PCs

6 SciSys & Astrium SOIS Projects Demonstrator Integrate SOIS Software Suite with other avionic components to illustrate use of SOIS in context
