3 CSA EO Program Three elements: Environment Resource and land-use management Security and foreign policy A history of success: RADARSAT-1 SciSat-1 RADARSAT-2 ESA programs (ERS-1/2, Envisat) NASA instruments (MOPITT, Cloudsat) Other instruments (WINDII, OSIRIS)

4 RADARSAT-1 Status Over 10 years of operations twice planned lifetime 32 data receiving stations and 22 archive facilities worldwide Average system performance > 95% (product quality and calibration fully maintained) Total minutes of data: 404,174 Total orbits completed: 54,255 Total user requests: 230,730 (as of March 2006) Operations confirmed until March 2009

5 RADARSAT-2 Mission Objectives & Innovations One of the key priorities of the Canadian Space Program: Responding to the challenges of monitoring the environment, managing natural resources and performing coastal surveillance. Objectives: Provide SAR data continuity from RADARSAT-1 Meet user needs for new applications opportunities Maintain Canada's position in the commercialization, utilization and development of advanced operational SAR capabilities Innovations Unique partnership with industry Advanced imaging modes

6 CSA-MDA a Public-Private Partnership MDA Design Authority Will own and operate RADARSAT-2 MDA-GSI will sell and distribute RADARSAT-2 SAR imagery worldwide Canadian Space Agency Technical expertise and Interface with other Canadian Government Departments CSA will manage the RADARSAT- 2 data allocation within the Canadian Government All Canadian Government Departments and Agencies will be provided RADARSAT-2 data to support their mandate Data allocation can also be used for scientific, R&D and noncommercial institutional use

22 What's Next? The RADARSAT Constellation Mission

23 Commitment to Continuity RADARSAT Constellation program rooted in government decisions: Cabinet approval-in-principle December 2004 Budget 2005 announced funding of development phases Treasury Board Preliminary Program Approval June 2005 Objective of program: Provide C-band SAR data continuity to existing RADARSAT users (not system continuity) Provide a System of three satellites to enhance operational use of C-band SAR data for: marine surveillance and sovereignty, environmental monitoring and disaster management
