Canadian Space Agency Assets STG coordination meeting STG 2 Darmstadt Nov , 2007 Yves Crevier Until Official STG rep is identified

Presentation Outline Canadian Space-based assets for IPY - a custom fit Data archive ASAP framework and data collection Opportunities Way forward

Canadian Space-based Assets RADARSAT series –Active sensor – ideal for polar imaging activities –Flexible imaging configuration – high and low res., narrow and synoptic coverage, land and water surface –High frequency of revisit –VERY RICH Polar archive (North and South) Other assets –Scisat –Anik F2 Envisat ASAR and Meris – within the data policy framework as agreed with ESA

RADARSAT 1 In operation since 1996 – confirmed continued operations until 2009 Demonstrated potential for routine polar observation (world-wide ice services, Arctic and Antarctic missions) Archive collected over both polar regions (>250,000 images over the Arctic)

RADARSAT 2 Ensured data continuation + enhanced modes until 2012 Canadian government data allocation available for International Science Projects

RADARSAT Constellation Mission (RCM) 3 satellites – C-Band, dual-pol operations, quad-pol exp.,multiple swaths and resolution available –Increased imaging frequency for polar regions – up to 4 time/day –Increasing operational use –Improving system reliability

Canadian Space-based Assets RADARSAT seriesRADARSAT series –RADARSAT year archive –RADARSAT 1 - New acquisitions to enhance the value of the archive – Satellite available until March 2009 –RADARSAT 2 – Use the Canadian Government data allocation for science activities under IPY –RADARSAT Constellation Mission – IPY Legacy Focus on National and International consultation and coordinationFocus on National and International consultation and coordination

SCISAT Improve understanding of the depletion of the ozone layer, with a special emphasis on the changes occurring over Canada and in the Arctic. SCISAT focuses its attention in the stratosphere, where the ozone layer is located.

ANIK F2 Access for communities in the far and mid-north, and in remote areas of Canada of low-cost, two-way satellite delivery CSA's total investment of $80 million in Anik F2 - provide the Government of Canada with $60-million worth services

Background Mission Highlights Systematic global land mass SAR coverage and stereo coverage of entire continents suitable for topographic mapping; Usage of different RADARSAT imaging modes, such as ScanSAR, Standard, Fine, and innovative right-left looking modes; Repeat coverage including InSAR coverage, of selected regions as a means to detect change; and Selected thematic coverage, including Arctic ocean, Antarctic, glaciers and ice caps.

RADARSAT 1 Archive Archive is "information rich" – as it was constituted by coherent data acquisition plans (multi-date, varying geometry, varying coverage, seasonally coherent) Significant repeat coverage allows unique change detection, thematic analysis opportunity Complimentary to existing data – optical framework, mapping databases, etc.

RADARSAT 1 Background Missions

Arctic Science Archive Processing (ASAP) To increase the use of RADARSAT 1 archive under the IPY Framework and other national priorities Focus on National and Int'l consultation process Initiate the processing of a significant portion of the RADARSAT-1 Canadian archive - received through direct reception at GSS and PASS or recorded data that was played back in Canada Preparation for RADARSAT-2 era; Canada maintaining leading position in space-based SAR remote sensing

Challenges Data policy Distribution framework for Radarsat-1: Commercial Radarsat-2 owned and operated by MDA – use of Canadian Government Data Allocation Restricted to science use – NO operations supported Costs related to the data processing in the archive Broad dissemination and return on investment

Summary RADARSAT data & products are available, contributing to Canadian and International goals for Polar sustainability, resources management, sovereignty, and science Canadian EO satellite coordinated with global goals and data demand and supply. National and Int'l consultation to guide strategic development of RSAT dataset and optimal use of its resources Coordination with other Information Network managers and linkages
