  1. CCSDS SOISWireless Working Group ESA Presentation of past, current and foreseen activities Meeting on April 20-24, 2009 Colorado Springs, USA

  2. Past wireless studies at the ESA • Optical Wireless Links for intra-S/C communications (INTA, Completed 2001) No EMC Issues

  3. Past wireless studies at the ESA • Optical Wireless Links Demonstrator (INTA, Completed 2004)

  4. Past wireless studies at the ESA • CDF “WiFly – Fly-by-Wireless Spacecraft Avionics Bus” (2006)

  5. Past wireless studies at the ESA • Optical Wireless CAN Bus Onboard Foton-M3 capsule (INTA, launched 2007)

  6. Past wireless studies at the ESA • RF Wireless/Optical Intra-spacecraft Demonstrator for Intra-Spacecraft communications • Oerlikon (CH), completed in 2007

  7. Past wireless studies at the ESA • Wireless Sensor Motes for Onboard S/C Networking and Inter-satellite Formation Flying communications (SSTL, Completed 2007)

  8. Past wireless studies at the ESA • Optical Wireless intra-spacecraft communications (INTA, ongoing, to complete in 2008) • Optical, Powering techniques, trade-offs, TRL5-demonstrator • Study of spaceborne applications of optical wireless comms

  9. Current wireless studies at ESA RF Wireless for Intra-spacecraft • Assessment and demonstrator (Venus Express) for Wireless Sensor Networks (SEA, ongoing, to complete in 2010) • 802.15.4, TinyOS vs Zigbee, Power mgnt… • WSN evaluation for Launchers (SEA-Astrium, ongoing, to complete in 2010)

  10. Current wireless studies at ESA • Implementation of a SpaceWire-to-802.11n bridge (SEA-4Links, ongoing, to complete in 2010) • Implementation of a CAN-to-Bluetooth bridge (SEA-SSC, ongoing, to complete in 2010)

  11. Current wireless studies at ESA Wireless Sensor Networks for Planetary Exploration (to complete in 2010) • Assessment of scenarios using WSN to support PEx missions; modeling and breadboarding activities

  12. Current wireless studies at ESA Fractionated Satellites (to complete in 2009) • Discovery study with the following objectives: • Define system architectures, comparative assessments and TRL of enabling technologies; determination of the added value of fractionation

  13. Future studies which ESA intends to pursue • Ultra wide band (UWB) communication • For sensor communications (typically: pulse,1.5Mbps, 500MHz bdw…) • Interesting characteristics: • Communication under the noise level: EMC concerns greatly reduced • Power consumption extremely low (lower than actual technologies) • RFID study and demonstrations • For ATV Cargo applications • Is to follow MB recommendations… • Satellite wireless access point on launcher for monitoring of the passenger • Objective is to define, design, manufacture and test a breadboard of a Satellite Wireless Access point on launchers for monitoring of the passenger satellite (http://telecom.esa.int) • Heat Shield wireless instrumentation proof-of-concept • Internal laboratory activity
