  1. Polar Communications & Weather (PCW) Mission Aurora Borealis

  2. Dual Objectives:Communications & Weather • Reliable communications in the high latitudes (North of 70º) to ensure: • Security • Sustainable Development • Support to Northern Communities • Air and Marine Navigation • Provide high temporal/spatial resolution meteorological data above 50º N in support of: • Numerical Weather Prediction • Environmental monitoring, emergency response • Climate monitoring

  3. Mission Requirements • To provide continuous meteorological service and information for the entire circumpolar region, with the imagery data “refreshed” as frequently as practical. GOAL 15 min • To improve weather prediction accuracy and timeliness by providing high quality data currently not available or available with insufficient spatial / temporal resolution • To improve the monitoring and prediction of air quality variables • To improve the modeling of physical processes in the Arctic environment • To develop measures of climate change through high quality monitoring of key atmospheric and surface variables • To improve observation and forecasting of space weather • To have a proto-operational system in place by 2014.

  4. Area of Interest Meteorological Coverage Requirement Meteorological Coverage Goal Communications Coverage Requirement

  5. Mission Overview • Architecture: • Constellation of two satellites in HEO (Molniya-type, 12 hours) • Orbit: • Two planes with apogee over Atlantic and Pacific (TBC) • Payloads: • Communications (Ka-band) and Meteorological payload suites on each satellite • Bus: • Canadian SmallSat Bus • Ground segment: • Based on existing Canadian infrastructure with potential addition of the Northern Ground Station • Operations: • Government operated (TBC) • Launch: • 2014 and 2015 • Lifespan: • 5 years-requirement, 7 years - goal • Partnership: • Open for International and Public-Private Partnership

  6. Applications and Products • Winds from sequences of images: high priority product • Surface type analysis: ice, snow, ocean, vegetation and surface characteristics such as emissivity, albedo, vegetation index • Surface temperature, detection of boundary-layer temperature inversions, diurnal cycle • Mid-tropospheric q/T sensitive channels for hourly direct assimilation complementing GEO radiance assimilation • Volcanic ash detection • Smoke, dust, aerosols, fog in support of air quality models and environmental prediction: • Total column ozone: • Cloud parameters: height, fraction, temperature, emissivity, phase, effective particle size. • Broadband outgoing radiation: total, Vis, IR, window

  7. Proposed imager channels (21)based on ABI, MODIS heritage

  8. Phase 0 Overview • Phase 0 closed out September 30, 2008 • Identified and validated comprehensive Users Requirements (UR Document) • Proved pertinence of the mission to the national and international priorities of the Government of Canada • Demonstrated feasibility of the technical solutions

  9. Phase A Overview • Status • Phase A1 (October 2008-March 2009) - committed • Phase A2 (April 2009 – November 2009) – planned • Expected Main Outcomes: • Successful Preliminary System Requirements Review • System Requirements Document • Ground Segment Requirement Specification (update) • Spacecraft Requirement Specification (update) • Bus Requirement Specification • Meteorological Payload Requirement Specification (update) • Communication Payload Requirement Specification (update) • Mission Development Plan, including lifecycle cost • Treasury Board submission seeking phases B/C/D approval

  10. Partnership Opportunities • Phase A1: • Extension of membership in the Users & Science Team to the international partners  URD final release • Phase A2: Joint Definition Study • Via CSA: government and intergovernmental agencies • Via Prime Contractor: private/commercial entities • Phase B and beyond: • Partnership mission (International and/or PPP) (TBC). • Open for Partnerships!! • Some discussions w/Finland have taken place • Norway meeting • US and Russia
