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. Mission Requirements Document URD was used as the input to the development of the MRD. This hi-level document is keeping updated to ensure that the end-to-end system meets the mission objectives and user requirements. Users involvement

13. Average Daily Coverage of Marine AOIs Accessibility with 3 satellites of Cdn marine zones at Medium 50m resolution
14. 4-day coverage of AAFC AOIs with all ascending passes using the Med Res 30m mode.
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
During Phase A, the CSA formed the User and Science Team (U&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&ST culminated in the development of a User Requirements Document (URD) with input from all stakeholder departments and their representatives.
