RFA Summary from GSRT PDR
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

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.

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. Ground System Verification Test Phase Test Responsibility Conductors Test Types Purpose Problem Tracking Phase #1 Element/subsystem Development Tests Implementation Manager Element Developers Unit, System Internal development Verification of Level 4 Requirements Internal developer Phase #2 Element Acceptance Tests MOM FOT, SOT, SDOGS Team Acceptance Testing Development Verification of L3/4 in OPS environment CDS for NASA Ground System Phase #3 Ground System Readiness Testing GSRTM GSRTT Readiness Testing (Including SOC Integration) Integrated Functional L3 Verification CDS Phase #4 Spacecraft Testing with the Ground System MOM FOT, SOT E-T-E Type Tests Functional Verification with S/C opportunities PR/PFR Phase #5 Operational Tests and Simulations MOM FOT, SOT, SDOGS Team OPS Scenarios, Simulations Operational Readiness PR/PFR The Ground System Readiness Test Manager (GSRTM) has overall management responsibility for all phases of the SDO Ground System Testing.

Test 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 system’s 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.

Test Phases (cont.) Spacecraft – Ground System Tests, Phase 4

Test 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,

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 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 I&T 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
