Why: Raison d’êtreWhy: Raison d’être

RADARSAT-2 is a Public-Private Partnership (PPP)• Private / Commercial

• MDA owns, operates the satellite and ground segment, and holds the worldwide distribution rights to RADARSAT-2 products

• Public / Government of Canada• GoC financial contribution provides pre-paid SAR

imagery to the Canadian Government User Departments and other Stakeholders

• CSA manages the Data Credit Allocation on behalf of GoC

Management of RADARSAT-2 Management of RADARSAT-2 Government data allocation Government data allocation

• Credit management and planning• Processing agreement• Reporting• Assistance to users in the identification of their data needs

RADARSAT Constellation MissionRADARSAT Constellation MissionNext GenerationNext Generation

RADARSART Constellation Mission RADARSART Constellation Mission Key DriversKey Drivers

• Continuity of C-Band SAR for Operational Users• Improved revisit over wide areas• Responsive Ground Segment (tasking and

latency)• Smaller, more cost efficient satellite development• Improved reliability (i.e. redundancy and

scalability)• Evolution to wider Operational use• Government-owned and operated

RCM Imaging Modes RCM Imaging Modes

RCM Data PolicyRCM Data Policy

Basic principles under considerations: • Serve the operational needs of Canadians (public and private users)

• Provide free, open and easy access to data to the largest possible extent

• Support the development of a level-playing field for the value-added

industry

• Ensure continuity of the commercial thrust of the RADARSAT missions

• Contribute to the study of long-term scientific phenomena

Data Utilization & Applications PlanData Utilization & Applications Plan

•Ensure Optimum use of the data when system becomes operational for Canadian Government Users

•Facilitate the integration of RCM data into existing operational applications of RADARSAT-1 and RADARSAT-2.

•Support the integration of RCM data into applications that have been demonstrated to the point where they are fully integrated into the operations of OGDs in support of their mandates

•Support science, research and development activities for potential new applications or improve existing ones.

•Facilitate the utilisation and access to data, product and services produced by RCM to users.

Challenges aheadChallenges ahead

• Maintain data continuity until RCM is launched

• Reduce conflicts within Government of Canada• Maritime users• Land users

• Assess new beam modes for GoC use

• Prepare stakeholders for RCM• Compact Polarimetry• Coherent Change Detection & Fast Revisit• Development of Value Added Products
