Polar Communications & Weather

(PCW) Mission



Dual objectives communications weather
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

Mission requirements
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.

Mission overview
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

Applications and products
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

Phase 0 overview
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

Phase a overview
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

    • Communication Payload Requirement Specification (update)

    • Mission Development Plan, including lifecycle cost

    • Treasury Board submission seeking phases B/C/D approval

Partnership opportunities
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
