IMAS 1: Argentina National Acquisition Plan

Argentina National Acquisition Plan - User requests

• 20 Application Areas identified by CONAE (through National Space Information Cycles programme, user surveys, own requests)

4 of 55



Argentina National Acquisition Plan - User requests

• User requests should contain information about (all or partly):

– Objective (scientific/operational)

– Region of Interest (shape file)

– Observation time window

– Observation frequency

– Spatial resolution

– SAR specific parameters (polarisation, off-nadir)

– Dawn/dusk (asc/desc) preferences

5 of 55



User requests Programming specifications

User requests are translated into relevant programming parameters:

– SAR acquisition mode

– PATHs intersecting the RoI

– Start/end latitude for each PATH

– Satellite cycle number(s)

– DESC and/or ASC

6 of 55



User requests: Conflict resolution

• Conflicts handling:

– Separation by time (cycle)

– Separation by observation direction (DESC/ASC)

– Modification of PATH coverage

– Separation by SAO-1A/SAO-1B (Epoch 2)

• Attention will be taken to assure that request modifications do not compromise requests' original science/operational objectives

Final Remarks

• An Integrated Mission Acquisition Strategy (IMAS) for SAOCOM- 1A and 1B has been developed.

• The work has included the development and implementation of an Acquisition Plan for Argentina, here presented.

• Internal conflict analysis and iterative refinement of requests have been undertaken without compromising the science goals.

• All the components of the Integrated Mission Acquisition Strategy, in particular the Acquisition Plan for Argentina, respond to the objectives of the Baseline-, Foreground- and Background Missions of SAOCOM.

• It is fully compliant with the SAOCOM Key Mission Scenario Requirements (L2A), and it is conflict free.
