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


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


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

CFS24/7 Forest Fire Monitoring with 15min to 30min update cycle


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

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.
