Polar Communications & Weather (PCW) Mission

1. Polar Communications & Weather (PCW) Mission Mike Manore, Louis Garand, David Bradley - Environment Canada Guennadi Kroupnik– Canadian Space Agency

2. Motivation for an Arctic Mission • A rapidly changing environment • rapidly diminishing icecover, amplified climate change • region of high meteorological and climate significance • Growing need for operational information infrastructure • increased marine and air traffic – civilian and military • economic development, services, sovereignty • for support to operations, safety, regulation, science • A gap in global communications and observation systems • lack of braodband satcom >75° • sparse in-situ observing networks • geostationary observing systems not suitable >55° • Other • support for Canada’s Northern Strategy • economic development • environmental protection • sovereignty • active region of space weather

3. Polar Communications and Weather Mission - Objectives • Reliable communications and navigation servicesin the high latitudes (North of 70º) to ensure: • - seamless 24/7 broadband, two-way connectivity • - uninterrupted data (IP) transfer • - interoperability with existing communications services • High temporal/spatial resolution meteorologicaldata above 50º N in support of: • Numerical Weather Prediction (short to medium range) • Environmental monitoring, emergency response • Climate monitoring • Space Weather Monitoring • Canadian-led mission with international partnerships • Canadian Space Agency leadership

4. Payloads and Mission Primary Payloads (Core mission): Ka-band (4 beams) and X–band (1 beam) 2-way High Data Rate communication Imaging Spectroradiometer (16-20 channels, 0.5-1 km VIS, 2 km IR) Space weather suite of instruments Secondary Payloads (Enhanced mission) Additional mass and power capacity may permit secondary payloads(under evaluation); e.g.; GNSS augmentation, Air Traffic Management Science instruments: Broadband radiometer, Aurora Imager, Atmospheric composition instrument (UV-NIR), Fourier Transform spectrometer (IR, similar to IASI) Technology demonstration: Software defined radio, V-band communications

5. Areas of Interest Meteorological Coverage Requirement (50ºN) Meteorological Coverage Goal (45ºN) Canadian Communications Coverage Requirement (may be expanded in enhanced mission)

6. Mission Overview • Primary (Core) Mission • 2 satellites in HEO orbit • Molniya or other – tbd • 2-way, 24/7 high data rate communication services • up to 12 Mb/sec • Ka-band + X-band • GEO-like imagery 50-90 N • 15-30 min refresh • 16-20 ABI-like channels • 0.5-1 km VIS, 2 km IR • Space-weather sensors • tbd based on final orbit • Secondary (Enhanced) Mission (tbd) • GNSS augmentation • Air Traffic Mgt • Science instruments (at proposal stage) • e.g., auroral imager, broadband radiometer, UV-NIR, FTS, …
