Canadian Space Agency, St. Hubert, Canada

As part of ongoing IPY Space Task Group activities, the Canadian Space Agency hosted an IPY SAR/InSAR workshop in response to an action item from STG-1.

The goal of the meeting was to develop an acquisition strategy for SAR and InSAR data that achieves the maximum number of IPY science objectives in such a way as to distribute the acquisition load across the different agencies – understanding that no single agency can accommodate all of the tasks. This will require a level of coordination between the space agencies that has not yet been attempted. The workshop focused on data acquisition requirements, as outlined by the scientific community, based on Agency strategic plans for IPY and unique capabilities of their systems. Data processing and distribution issues were briefly addressed but the primary objective was to populate the archive given the unique opportunity of IPY.

The workshop main tasks were:

1) To review existing GIIPSY science requirements as outlined in the Global Inter-agency IPY Polar Snapshot Year (GIISPY) Strategy Document.

2) To present the Agencies strategic priorities in line with IPY science activities.

3) To present and review SAR data which are being collected, and are planned for collection during the IPY.

4) To present the satellite and ground segment operators system capabilities and constraints related to the acquisition of data in support to IPY.

5) To attempt to forge a coordinated / multi-agency SAR acquisition plan for the remainder of IPY acquisitions.

In order to meet these ambitious objectives, invited attendees, which include members of the science and operational communities, space agencies operating SAR satellite; space agencies with data transmission, ground segment and processing capabilities, and ground segment operators, were requested to actively contribute to the achievement of the workshop objectives.

As a follow up to the STG action to enhance the coordination among the SAR Space Agencies in response to the IPY scientific objectives, a SAR/InSAR coordination workshop was held on 5/6 March 2008 at the Canadian Space Agency. As a result of this meeting, the SAR operating Agencies agreed on the strategic guidelines for imaging activities and for thematic priorities as outlined by the science community. Despite the significant way forward and considerable efforts we are putting to fulfill our commitments, there is still a need to develop a SAR Acquisition Consolidated Plan and discuss the way forward for a SAR processing strategy and data dissemination plan.

As part of the SAR coordination process, the German Aerospace Center (DLR) is organising a second meeting to address the harmonisation and coordination of the acquisition plans. The objectives of this meeting are:

* Consolidate the current SAR planning and imaging activities occurring under the auspices of IPY/STG in order to avoid gaps and overlaps and optimize resources (i.e. thematic / instrument matrix, common planning tool, etc.)
* Distribute imaging load according to Agencies’ capacities and priorities, and develop acquisition plans
* Look at a short/med/long term planning approach to continue the acquisitions (if at all possible)

The meeting will be held at the DLR facilities in Oberpfaffenhofen (Germany).
We now established the date of the workshop on 30 Sept./1 Oct.2008.

DRAFT Agenda

GIIPSY Draft Acquisition Plan Recommendation for TSX.

These plans were prepared to provide DLR with an estimate of SAR loading for Antarctic regions south of about –80°. Comments welcome. These are in addition to any individual proposals and to several super-site areas that the STG is considering in Greenland and Antarctica.
