Mission Overview Living with a Star
In order to meet the needs of the Living With a
Star program and determine the drivers and
diagnostics of solar activity and variability
which affect Earth and humanity, the Solar
Dynamics Observatory must

• Provide nearly continuous coverage of solar
  activity
• Provide coverage of the regimes (interior,
  photosphere, corona) in which the activity occurs
• Provide sufficient data on the types of phenomena
  which impact Earth, near-Earth space and humanity
• Observe over the relevant timescales (seconds to
  years) of solar variability

RFA Summary from GSRT PDR

• RFA 08
• Author Robert Schweiss, John Donohue, Glen
  Iona
• Summary We were asked to show how we would
  assure the performance of the DDS and the ability
  of the Ground System to meet science data
  requirement
• Resolution We provided more detailed information
  about the performance and testing of the DDS and
  the rest of the critical science data path,
  including an analysis of the Ground System
  availability and reliability.
• Status Closed.
• RFA 19
• Author Steven Bundick
• Summary Long-term testing of the Ka-band
  tracking capabilities was recommended.
• Resolution Long-term testing of the Ka-band
  tracking capabilities will be incorporated into
  the GSRT Plan
• Status Closed.

12
GSRT Objectives Responsibilities

• Develop the Ground System Readiness Test Plan
• Establish an integrated test effort from
  acceptance testing through to operational
  readiness
• Verify that the Ground System can support all
  mission requirements in an integrated, end-to-end
  configuration.
• Provide an independent, documented record of
  Ground System performance, test discrepancies,
  and corrective actions.
• Establish and lead the Ground System Readiness
  Test Team in meeting these objectives.

13
GSRT Verification Approach
Ground system readiness is determined through a
series of System, Acceptance, Integration tests,
and Mission Simulations. This Verification Chart
shows the test phases, purposes and responsible
test party.

has overall management responsibility for all
phases of the SDO Ground System Testing.
14
Test Phases

• Element Level Testing, Phases 1 and 2
• Software, hardware provider System Testing to
  verify level-4 requirements development

• Test configurations, and processes for
  discrepancy tracking, resolution and retest.
• Test readiness dates, dependencies and
  objectives.

  process for test procedure development
• Requirements traceability and verification
  tracking
• Test Resources and responsibilities
• Ground System Test team personnel roles and test
  responsibilities,

17
Test Team Responsibilities

• The ground system verification process is planned
  and carried out through the Ground System
  Readiness Test Team (GSRTT) under direction of
  the Ground System Readiness Manager (GSRM).
• The GSRTT is comprised of ground system element
  personnel, quality assurance representatives, FOT
  and SOC personnel and simulator, test beds and
  test tool representatives
• The GSRTT members will be responsible for
  developing the detailed plans and scripts for the
  ground system tests and simulations, and for
  analyzing and documenting results.
• A test script, briefing message or other
  coordinating email will be distributed to ensure
  that all test participants have the information
  needed to conduct the test
• The GSRTT will meet to plan tests, distribute
  test notification messages discuss the test
  results, and provide a test report, The report
  will be distributed to document the test results,
  track the verification completion and identify
  retesting
• GSRTT will interface with the spacecraft IT and
  launch team to support spacecraft testing.

Test Discrepancy Reporting

• A Test Discrepancy Report (TDR) is generated when
  the ground system fails to meet a functional test
  requirement.
• Each TDR is assigned to an actionee element(s)
  for investigation and resolution
• Each TDR is entered into the Comprehensive
  Discrepancy System(CDS) which automatically
  notifies the relevant parties
• Test discrepancies are prioritized (Critical,
  Urgent, Routine), tracked, reported, resolved and
  retested
• The ground system TDR status relating
  requirements to discrepancies is presented
  monthly and at all reviews
