4Mission 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

11RFA 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.
12GSRT 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. -
13GSRT 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.

The Ground System Readiness Test Manager (GSRTM)
has overall management responsibility for all
phases of the SDO Ground System Testing.
14Test Phases
- Element Level Testing, Phases 1 and 2
- Software, hardware provider System Testing to
verify level-4 requirements development - Element Acceptance Testing to verify internally
the operational systems level-3/4 functionality - Spacecraft development and test using some MOC
and DDS sub-systems - Ground System Readiness Tests (GSRT), Phase 3
- Building block integration tests verifying the
ground system level-3 requirements - Demonstrate element-to-element interfaces and
functional compatibilities - Verify ground system end-to-end compatibility
with the observatory and SOCs - Verify the ground system functional capabilities
and status prior to FOT tests with the spacecraft - RF Compatibility Tests, Phase 3
- Verify Spacecraft RF compatibility with ground
station equipment by testing at GSFC - Verify the Spacecraft RF compatibility with the
SDOGS and USN ground system antennas and other
systems by testing onsite.
15Test Phases (cont.)
- Spacecraft Ground System Tests, Phase 4
- Validate ground system functions and interfaces
with spacecraft realtime data and responses - Provides Operations preparation for spacecraft
launch and flight control - Conducted with Spacecraft under IT Team control
and ground system under FOT control - Mission Operations Simulations, Phase 5
- Verify procedures and personnel operations in
long term duration operational environments - Demonstrates launch readiness using actual flight
plans, procedures, and personnel - Develops an operational team consisting of
Project, Spacecraft, SOC, Ground, and FOT

16Test Planning
- The Ground System Readiness Test Plan (GSRT)
describes the verification process. The GSRT
Plan specifies - Test Methodology and Management to carry out
ground system verification and readiness for
spacecraft test opportunities. - Verification of level-3 requirements
- Test configurations, and processes for
discrepancy tracking, resolution and retest. - Test readiness dates, dependencies and
objectives. - Test requirements, test cases, resources and the
process for test procedure development - Requirements traceability and verification
tracking - Test Resources and responsibilities
- Ground System Test team personnel roles and test
responsibilities,
17Test 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.

52Test 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
