  1. Onboard Data Processing Units Main task • Development of hard- and software for flight instruments Main research topics • Magnetospheric MultiScale • Development of the EDI electron gun and control logic • Solar Orbiter • Digital processing unit for the Radio & Plasma Wave Analyzer • CHEOPS • Digital processing unit Refereed publications (since Jan 2013) • Total: 2 IWF/ÖAW

  2. Who are we? Lead: Manfred Steller Members • Staff: J. Hasiba, K. Hofmann, G. Laky (QA), S. Neukirchner, H. Ottacher, M. Steinberger, (H. Hartl left) Cooperation within IWF • Magnetotail Physics (Nakamura et al.): Electron gun for MMS • SW-Atmosphere (Lammer et al.): COROT, CHEOPS • Magnetometer Team (Magnes et al.): Magnetic cleanliness, parts • SW Turbulences (Narita et al.): Solar Orbiter/RPW • Radio Wave Group (Fischer et al.): Solar Orbiter/RPW Key external collaboration • France: LESIA, CNES; Switzerland: University of Berne; USA: UNH; IWF/ÖAW

  3. EDI: Gun Detector Electronics • Contribution • Coordination of GDE development at RUAG Space Austria • Design of digital electronics • Design, programming and test of FPGA logic Highlights • Specific sigma-delta DAC design for quick response & accuracy with low clock rates • Code generator and correlator to derive time of flight IWF/ÖAW

  4. EDI: Electron Gun and Electronics Contribution • Development of electron gun(electronics, mechanics) • Electron source provided by UNH • Calibration of gun • Status • All flight models delivered • Two models undergo refurbishment • Further investigation together with UNH to understand problems with HV opto- coupler IWF/ÖAW

  5. Solar Orbiter / Radio & Plasma Waves Contribution • Development of DPU electronics • Redundant DPU hardware • Boot software (reliability class B) IWF/ÖAW

  6. CHaracterizing ExOPlanet Satellite Contribution to CHEOPS • Back-End Electronics • Industrial contract (RUAG Space Austria): • Power supply for entire Electrical Sub-System • Stringent requirementsfor camera supply • Redundant unit • IWF activities: • Development of dataprocessing unit • Fully redundant system • Boot software IWF/ÖAW

  7. CHaracterizing ExOPlanet Satellite Differences to Solar Orbiter RPW DPU • S/C interface MIL-1553 • Dual core processor GR712 • FLASH memory to be used as telemetry buffer • Hardware for thermal control of instrument operational heater IWF/ÖAW

  8. Future Plans: 2015-2018 MMS: EDI GDE & Gun • Support for integration tests • Support for commissioning phase Solar Orbiter: RPW/DPU • Delivery of QM end 2014 • Delivery of FM in 2015 • Support for instrument integration CHEOPS • Design activities to PDR in 2014 • Integration of EQM begin 2015, delivery mid 2015 • Integration of FM Q3 2015, delivery begin 2016 IWF/ÖAW

  9. Thank you IWF/ÖAW
