GEO and HEO weather satellites: natural partners

Sixth GOES User’s Conference

Madison, WI

November 3-5, 2009

Louis Garand (EC) and PCW U&ST

2 sat constellation in molniya orbit continuous views over one pole
2-sat constellation in Molniya Orbit = continuous views over one pole

2 satellites to provide

continuous GEO-like

imagery 50-90 N

0.5-1 km VIS

2 km IR

12-h period

63.4 deg. inclination

Apogee: ~39,500 km

Perigee: ~600 km

canada s polar communications and weather pcw dual objectives
Canada’s Polar Communications and Weather (PCW): Dual Objectives
  • Reliable communications in the high latitudes (North of 70º) to ensure:
    • Security
    • Sustainable Development
    • Support to Northern Communities
    • Air and Marine Navigation
    • Arctic Science
  • Provide high temporal/spatial resolution meteorological data above 50º N in support of:
    • Numerical Weather Prediction (short to medium range)
    • Environmental monitoring, emergency response
    • Climate monitoring

PCW to have an operational status linked to NRT meteorology

Launch target: 2016
