LAT-Level Test Documents

LAT Level Test Procedures

The steps for execution of the Limited Performance Tests, Comprehensive Performance Tests, LAT Functional and FSW Test, and TCS Functional Test during the various phases of LAT-level testing at NRL are described in the LAT-PS-07836: LAT Test Procedure with LICOS. This document describes how the LICOS system is used to execute the test cases defined in LAT-MD-02730: LAT Performance & Operations Test Plan.

The test procedure for Sine Vibe testing is presented in LAT-PS-08112 GLAST LAT Protoflight Sine Vibration Test Procedure.

The test program for EMI/EMC testing is presented in LAT-MD-02726 LAT EMI/EMC Test Plan.

The test procedure for Acoustic testing is presented in LAT-PS-08113 GLAST LAT Protoflight Acoustic Vibration Test Procedure.

The test procedure for Thermal Vac testing is presented in LAT-TD-06799 LAT Thermal Vacuum Test Procedure.

The test procedure for Mass Properties/Weight CG testing is presented in LAT-TD-08114 GLAST LAT Mass Properties Test Procedure.

Performance and Operations Test Reports, Test Logs, and Requirements Sell-off Packages

The following sections present the run records and links to test reports, test logs, and sell-off packages corresponding to the test activities defined in the , as illustrated in the figure above. For convenience, these records are split and presented by test type (comprehensive performance tes, limited performance test, etc.). The full record of the test flow starting with the Post-Ship CPT is presented in this spreadsheet. The full record of the test flow starting with Thermal Vac testing is presented in this spreadsheet.

Comprehensive Performance Test Results

As shown in the flow diagram above, Comprehensive Performance Tests are executed in several phases of the LAT-level test program. Outputs of all tests in the sequence are stored in the E-Log database developed and maintained by the LAT Integration and Test Team.

In this section, the CPTs are itemized and each is linked to a spreadsheet listing the test cases executed as part of that test and the associated E-Log run identifiers (RunIDs). Enter the RunID in the Run Range field of the E-Log query page to retrieve the test logs and raw test data associated with each execution.
