  • During Phase A, the CSA formed the User and Science Team (U&amp;ST) to engage the end user departments and scientific community to ensure their user requirements would be addressed and captured as early as possible in the mission. The primary work of the U&amp;ST culminated in the development of a User Requirements Document (URD) with input from all stakeholder departments and their representatives.
  • Medium, 50 m, maritime, one of four depending on incidence, each composed of 10 smaller beams. 350km High res 5 m, very HR, 3m @ 35° Quad pol resolution similar to HR, incidence selectable Scan = low-res, medium +, 30 m Low noise 30 m = 2 looks Others strip mode Spot 3m x 1m
  • Highlight the operational user areas (i.e. Marine) which are the most demanding drivers for the Constellation Also note that the land community is also covered
  • - Doppler centroid values from orbit and attitude data and Doppler Centroid values adaptively estimated from the signal data, on a grid with sample spacing no greater than 2 km in both ground range and azimuth.

    8. 8. User & Science Team The U&ST was formed at the early stage of the project (2005-phase A) to engage end user department to ensure requirements would be addressed and capture in the mission development. User Requirements Document U&ST primary work was to develop the URD including inputs from Canadian Government Departments stakeholders.

    26. 26. RCM – Sentinel-1 Collaboration The following collaborative activities are currently explored: • Joint / integrated pre-defined acquisition plans (complementarities in observations / modes, increased revisit, etc.) • Level 1 Product format • Harmonization of catalogue interface • Development of common tools • Harmonized communication, joint publications etc. • Joint calibration working group is being set up
    27. 27. Summary <ul><li>RADARSAT Constellation Mission is designed to continue/enhance the use of SAR to support Government of Canada operations as well as internationally </li></ul><ul><li>Support to government users for application development </li></ul><ul><li>Compact Polarization , Multi-pass/Frequent Revisit and 4-day CCD provide opportunities for new information and applications </li></ul><ul><li>Opportunities for synergy and collaboration with Sentinel-1 are being pursued seriously </li></ul>
