  3. Background • ISAS • Scientific output limited by downlink bandwidth. • Wish to increase RT data access. • Decrease risk by more contact possibilities. • ESA • No offer to community between SOHO and SOLO • Provide support for something that is important to project in exchange for data rights. • Support should have simple interfaces. • Norway • Involved with MSSL on EIS. • See the need for more data bandwidth. • Solar physics one of two national priorities. • Has suitable ground station on Svalbard. • Sees an opportunity to move ”non-science” resources into science.’

  4. Why Svalbard? • At 79 degrees latitude, all orbits of polar orbiting satellites >550 km. • Easy access and relatively benign climate. • Existing infrastructure for satellite downlink and commanding. • Infrastructure commercially developed; that is cost-effective. • Strong national support. • Investment by NSC of high speed communication to Svalbard.

  6. On top of the world • Well developed satellite communication, but costly. • NSC received offers 3-02-2003 to connect Svalsat and NSC Tromsø with optical cable. • Investment of 40-50 M€. • In operation from 2004 with an initial bandwidth of 10 Gbit/s. • By 2005 the largest ground station for polar orbiting satellites, NASA, NOAA, ESA, EUMETSAT.

  7. Norwegian Proposal • Unsolicited proposal from NSC to ESA to provide the ESA support to Solar B as fixed price contract. • Proposal includes: • 15 orbits/day downlink at 4 Mb/s for four years operation. • Transport of data to ISAS/Oslo. • Real time datalink to ISAS of up to 256 kb/s. • Build-up and operation of European data centre for Solar B data for four years operation and one year archiving phase. • High speed data links to European users. • NSC will subcontract the downlink/operation part to its subsidiary KSAT and the data centre to ITA/UiO.

  11. Not your common neighborhood! • Most of Svalbard protected. • No unarmed movement outside Longyearbyen. • Polar bear small but real danger.

  12. ESAs Decision Process • SPC decided in 2001 to collaborate with ISAS on Solar B by providing additional downlink capacity. • SSWG recommended 24-01-2003 the use of Svalbard for this. • SSAC gave its support 4-02-2003. • ESA Executive has to negotiate with ISAS what rights European scientists will receive for this investment. • Final go ahead in SPC pending a science management plan for the ESA side. February or May.

  13. Svalbard Downlink • Will provide additional 2.4GByte per day. • Norway will provide to ESA users a data centre in Oslo for data distribution and archive. • Oslo data centre will provide the required access filter as determined by ISAS/ESA. • Approximately 10 minutes RT data to ISAS every orbit. • Data archive of up to 24 Tbyte and high speed access. • Essential with a homogeneous level 0 data set everywhere.
