3 Success Drivers for Operational RADAR Services Operational applications are dependent on multiple mission and sensor characteristics Each SAR mission has its own strengths and weaknesses in these areas In this presentation, we highlight the importance of those factors that enable successful Near Real-Time service provision Tasking Laten ncy Taskin ng Priority Coverage Revisit Cosmo- RADARSAT Sentinel-1 TerraSAR Skymed Product Latency Image Quality Resoluti ion Ge eolocation Use, duplication, or disclosure of this document or any of the information contained herein is subject to the restrictions on the title page of this document. 3

4 The Evolving Definition of Near Real-Time Near real-time 1 : The delay introduced between the occurrence of an event and the use of the processed data. The term implies that there are no significant delays. What constitutes a significant delay, depends on both The application; and The expectations of the user community In the world of space-based monitoring and surveillance, the definition of NRT has undergone an evolution from: Circa 1995: Today: Within 4 hours of receipt of data at a ground terminal Less than 15 minutes from image acquisition 1 From US Federal Standard 1037C, Telecommunications: Glossary of Telecommunication Terms, Published August 7, 1996, Use, duplication, or disclosure of this document or any of the information contained herein is subject to the restrictions on the title page of this document. 4

5 NRT Requirements Span Multiple Applications An expanding set of operational applications require NRT service levels Oil and Gas Oil Spill Monitoring Disaster Management Flood Mapping Natural Resources Ice Monitoring Defence and Security Maritime Surveillance RADAR is well suited to provide NRT service for these operational applications because: Acquisitions are weather independent Incident Response Landslide Monitoring Illegal Fishing Target Change Detection Acquisition m odes can be optimized/tuned ized/tuned for the application Data processing can be highly automated.

7 Enabling NRT: Direct Access to RADARSAT-2 Direct downlink access from RADARSAT-2 For partners that operate Network Stations Provides a secure environment for rapid delivery Enables near real-time processing and services Telemetry agreements Allows direct order placement to the Order Desk Committed volume at discounted rates Zodiac Use, duplication, or disclosure of this document or any of the information contained herein is subject to the restrictions on the title page of this document. 7

8 Broad Network Providing Near Real-time Coverage New reception facilities in Canada s north enhance global NRT services. Northern access, however, is not a silver bullet. A global network of stations is required to minimize data latencies.
