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)

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

Government owned and operated systemOperational end-to-end system Three small satellites (scalable to six)Minimum average daily coverage of Canada and adjacent watersMinimum average daily global accessProvides medium resolution wide coverageData analyzed in near real time for operational applications4-day Coherent Change Detection using SAR interferometry Dual selectable co-cross polarisation and experimental quad pol modeGradual implementation and replacement of aging satellites

Main System Parameters

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

Polarisation
