Presentation Transcript

  1. Polar Communications and Weather (PCW) mission to serve the Arctic

  2. Three Major Components • COMS payload: Reliable communications in the high latitudes (North of 70º) to ensure – • Security • Sustainable Development • Support to Northern Communities • Air and Marine Navigation • METEO payload: Provide high temporal/spatial resolution satellite imagery data above 50º N in support of • Numerical Weather Prediction • Environmental monitoring, emergency response • Climate monitoring • Space Weather payload: Provide observation of space environment for monitoring and forecasting space weather

  3. Key Interests for NRCan ESS • Space weather : • Volume, mass and power are allocated for space weather instrument: one of three key PCW instruments – NRCan/ESS is a primary data user • Climate Change • Multi-spectral imagery to monitor the state of landmass and radiative fluxes over Canada and entire Circumpolar Arctic region -24/7 with 15min to 30min refresh rate • Polar Continental Shelf Project • Satellite imagery and communication capacity to support Arctic operations CFS • 24/7 Forest Fire Monitoring with 15min to 30min update cycle

  4. Value for Canada and Human Civilization • PCW will revolutionize the capability for Arctic monitoring and communications; • This is comparable to launching the first LEO and GEO satellites, the first man in space, the first mission to the Moon; • This project was a dream for two generations that will come true in 2016 ! • Canada is positioned now as the best nation in the world to achieve this • Space technology readiness • Data processing and assimilation readiness • Strong users needs and support from OGDs (EC, DND, INAC, DFO, DFIAT, CRC, NAVCAN among others) • Strong alignment with Government of Canada priorities in the Arctic

  5. PCW: Constellation in Molniya Orbit Aurora Borealis Source: CSA

  6. PCW Orbit Relative to LEO and GEO

  7. Mission Architecture Source: CSA

  8. PCW Orbit Timing

  9. Latitude-Longitude-Altitude

  10. Imaging From PCW Orbit (FOV equivalent H=24,000km)

  11. Viewing Artic Region From PCW OrbitTwo-Satellite System, VZA <900Continuous 24/7 Coverage

  12. Future steps • After successful completion of feasibility study (Phase 0), CSA is moving PCW project into Phase A; • CSA has invited NRCan to join as a partner, waiting for response; • Responding to a strong international interest and support CSA is developing the International PCW User and Science Team; • Four science groups from NRCan: CCRS, GEOLAB, PCSP, CFS, should be involved in the development of User Requirement Document and various PCW project components and applications.
