The Display Audit Suite is an integrated package of software tools that partly automates the detection of Portable Computer System (PCS) Display errors. [PCS is a laptop computer used onboard the International Space Station (ISS).] The need for automation stems from the large quantity of PCS displays (6,000+, with 1,000,000+ lines of command and telemetry data). The Display Audit Suite includes data-extraction tools, automatic error detection tools, and database tools for generating analysis spreadsheets.

These spreadsheets allow engineers to more easily identify many different kinds of possible errors. The Suite supports over 40 independent analyses, and complements formal testing by being comprehensive (all displays can be checked) and by revealing errors that are difficult to detect via test. In addition, the Suite can be run early in the development cycle to find and correct errors in advance of testing.

This software suite was developed by Chris Land of The Boeing Company and Kathryn Moye of the Dynacs Co. for Johnson Space Center. MSC-23630-1
