  1. WORLD CLASS – through people, technology and dedication WORLD CLASS – through people, technology and dedication

  2. International EOS/NPP Direct Readout MeetingOperational use of the Svalbard and Tromsø sites for near real-time direct broadcast data servicesBørre Pedersen, Jan Petter Pedersen, Line Steinbakk, Arnulf KjeldsenKongsberg Satellite Services, Tromsø, NORWAY • Content of presentation: • Introducing KSAT • The KSAT ground segment • Operational data and services • Wind/Coriolis • MODIS • Conclusions Svalbard Satellite Station Aurora, January 2005 Photo: B.Hillestad, KSAT

  3. KSAT - The Company • History • 1967-2002: Tromsø Satellite Station (TSS) • 2002 : Kongsberg Satellite Services • Kongsberg Defence & Aerospace(50%) Norwegian Space Centre (50 %) • Facilities • Tromsø - at 69° 39` N, 18° 56` E • Svalbard - at 78° 15` N, 15° 80` E • Grimstad (S-Norway) – Spring 2005 • TrollSat (Antarctica) – 2006/2007 • Staff: 63 (Tromsø 48, Svalbard 15) • Turnover: • 2001. 6,5 Meuro (51 MNOK) • 2004 Turnover: 13,5 Meuro (113 MNOK), net result > 15 % • 2005 Budget: +13,2 Meuro • Company business areas • Earth Observation • Ground Station Services

  4. KSAT Earth Observation • Focus on SAR missions • Radarsat-1 (1996), Radarsat-2 (2006) • ERS 1 and 2 (1991), Envisat (1/2003) • Near real-time operations (~minutes) • Round the clock near real-time operations • Provision of information services, e.g. Detection of oil spills, Ship positions • Direct downlink within Tromsø, Svalbard, Grimstad coverage areas • Global data access SvalSat, TrollSat and via ESA ground segment • New missions for service continuity and new products and markets • Introducing optical data and services

  5. Svalbard advantages 14 orbits per day Direct downlink, global data access Fiber cable since January 2004 Round the clock operations/services TT&C LEOP Support Data reception (S -X band) and distribution Back-up and anomally support Remote operations from Tromsø Network Control Centre (TNOC) Customers NASA: Terra, Aqua, ICESat, Coriolis, … ESA: Envisat, ERS-2, ADM/Aeolus EUMETSAT, IPO, CNES, RSI/Radarsat-2 KSAT Ground Station Services

  6. SVALSAT This Is How It Looks Like

  7. KSAT Grimstad antenna 3 meter antenna system, April-05 Data reception and ingest Operated & controlled from Tromsø Data distribution via land line Theoretical 3 deg. horizon

  8. KSAT Troll Satellite Station (TrollSat) • Complete 7,5 meter S/X-band data system • Completed by 2006/2007 • Commanding & control from Tromsø/TNOC • Satellite link data distribution • Customers • OrbView 5 (signed) • Other users: • TT&C and LEOP support • Data reception • Galileo • EUMETSAT/NPP/POESS meteorology • NASA missions

  9. KSAT ground segment & services • Svalbard = The polar meteorological satellite facility (IPO, Eumetsat) • Troll, Future meteorological site in Antarctica • SAR based services • Oil Spill detection • Ship detection for maritime security • Ice applications/data and services • Wind (speed, direction) information • Land applications • Snow & Flood mapping and monitoring • Other relevant/optical data and services • Terra, Aqua MODIS data • Coriolis WINDSAT data • TIROS-N NOAA/AVHRR data Svalbard Tromsø Grimstad

  10. KSAT data and derived services • MODIS data, increasing interest • snow cover mapping for hydropower production planning, • flood monitoring. •  KSAT provides MODIS data and derived products for snow mapping during the melting season as part of an EU FRP project Envisnow. • Development and provision of marine earth observation services, new oceanographic information services: • Oceanographic information, wind and waves, is needed to provide reliable services. • Growing need for wind and wave information to serve the met. communities in Europe. • Potential new services • ”Global” and fast access to (MODIS) optical data for European and Global users • MODIS polar winds • Coriolis/WindSat service

  11. Coriolis wind information service • Spaceborne wind measurements • ERS scatterometer data less availability • Japanese Adeos-2 satellite failed • Envisat does not operate a scatterometer. •  Operational institutional users in Europe such as met. institutes in a more difficult position with respect to service and information availability. • Emerging opportunity recognition • The KSAT capabilities to provide near real-time services • Coriolis Windsat knowledge and the data access via Svalbard, •  1) Mission found an increasing interest among European met. institutes. •  2) KSAT evaluated how a WindSat processing chain at Svalbard/Tromsø could meet European needs for fast access to wind speed and direction information. • A Coriolis wind service can and will complement KSAT Envisat ASAR NRT wind information service

  12. Proposed Coriolis mission and service scenario • Downlink regional mission data to Svalbard and a second KSAT ground station (Tromsø or Grimstad). 4-6 passes per day. • Downlink on-board recorded global data to Svalbard • Supplementary access based on downlink of data to US facilities • Additional stations further South in Europe if required by the users • Raw data distributed via fibre link to Tromsø. • Near real-time distribution of derived wind information via land lines to institutional European users Black line = raw data Red line = derived information

  13. Coriolis wind service mission scenario

  14. Direct read out MODIS data • KSAT operational reception of MODIS data • Direct downlink Tromsø, Svalbard and Grimstad • Global dump Svalbard under NOAA/NASA contract • Future MODIS data type continuity, and KSAT operational ambitions for ”one-stop-shop” • Expand current capabilities and services (web-based technology) • Delivery of (Level 1B) data to users/VA companies • Utilisation of MODIS (-type) data for operational services. 1. Information reliability improvement optical+SAR data e.g algae vs oil spills2. New services based on MODIS-type (Polar winds, snow cover mapping)

  15. MODIS services and data products Snow cover map (right) Derived from Terra MODIS (left)

  16. Other/commercial optical satellites • Digital Globe, OrbImage, SPOT (0,65m – 2,5m) • Formosat, Kompsat, THEOS, … • KSAT vision to serve these missions Digital Globe Tsunami, Sri Lanka 26.12. SPOT 5 France b/w 2,5m Multisp 10m

  17. Conclusions – The next step • Coriolis mission and the capability is known • Coriolis wind information will be a supplement to European institutional users/VA • Coriolis wind information may be included in KSAT wind service • Develop services based on the use of Svalbard and Troll and ESTABLISH A POLAR WORKING GROUP FOR DB APPLICATIONS
