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)
RADARSAT-1 Status
Over 10 years of operations – twice planned lifetime32 data receiving stations and 22 archive facilities worldwideAverage system performance > 95% (product quality and calibration
fully maintained)Total minutes of data: 404,174Total orbits completed: 54,255 Total user requests: 230,730 (as of March 2006)Operations confirmed until March 2009
RADARSAT-2Mission 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
InnovationsUnique partnership with industry Advanced imaging modes
Technical expertise and Interface with other Canadian Government DepartmentsCSA will manage the RADARSAT-2 data allocation within the Canadian GovernmentAll Canadian Government Departments and Agencies will be provided RADARSAT-2 data to support their mandateData allocation can also be used for scientific, R&D and non-commercial institutional use
CSA-MDA a Public-Private Partnership
Design AuthorityWill own and operate RADARSAT-2MDA-GSI will sell and distribute RADARSAT-2 SAR imagery worldwide

The RADARSAT Constellation Mission
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
Mission Concept

Main System Parameters
Dual cross selectable pol on all low and medium resolution modes; ‘experimental’ quad pol
Polarisation
