RFA 19 – Robustness of Operations Software
•
•
Specific Request
– Specify plans and requirements to ensure that software, particularly that “inherited” from I&T,
will be of sufficient robustness for operations use.
Response
– Using ITOS for LAT health and safety operations
– Plan to use existing automated notification software tools (such as FASAT or SOF RXTE) to
help assure reliable 24/7 operation of ISOC
– Other software tools
• ISOC will use existing software where possible
• ISOC will follow a complete verification and validation process, as described in LAT-SS02513-1 LAT ISOC Verification and Validation Plan
• The ISOC Test Plan document (to be released in April 2005) will provide the mapping of
all Level III requirements (in LAT-SS-0021-8) to software components
• Test procedures will be documented to cover each requirement (either in the Test Plan
or in a separate Test Procedures document)
– See attached SW development schedule for an outline of ISOC testing
• The test procedures will be followed before each release to verify that each requirement
is met (including regression tests of previously released features)
• A fully functional ISOC system will be available for control of LAT upon its arrival at
SpectrumAstro
• Schedule includes many months of operational use of software before launch (e.g.
during I&T and Mission Simulations)
