DCS Direction from Conceptual Design Review Slide 2 • Develop solid infrastructure • Data archiving • Data pipelining

Sterling DCS SOW • • • Systems Engineering Web Development and collaboration Software Development Operations Expertise Administrative Support Slide 3

Slide 4 Why Sterling Software • Over 50 combined years KAO operations experience (five staff) • Developers of the KAO data systems • Developers of the MCS • Members of the airborne astronomy community • Remote collaboration and web development expertise

Current Effort Slide 5 • Sterling supports USRA in DCS development – Draw upon in-house software expertise – Provide commonality between MCS/DCS development – Assist in MCS/DCS interface definitions – Draw upon current SOFIA lessons learned • trade studies, remote development, etc. – Active participants in all meetings and reviews

Systems Engineering Support • Requirements definition • System design and implementation • standards and process definitions • software integration • remote collaboration • Configuration management • Quality assurance • Previous airborne experience – Mission Ops. – Flight planning – Command control Slide 6

Slide 7 Web development/collaboration • Development of remote collaboration tools • Consultation on tools and capabilities • Recommendations for distributed development

Operations Expertise • Domain expertise – – – airborne astronomy data systems architecture algorithms ARC infrastructure • Operations analysis and engineering Slide 8

Software Development • Web software to integrate development products from DCS team • Establish observatory XML protocols and guidelines • Disseminate XML standardization activities Slide 9 • Knowledge and recommendations on: – archive development • Commonality of MCS and DCS archives (working versions) – object oriented development – documentation

Administrative Support • Admin support for key activities of DCS team – logistics – mailing lists – other communications • Configuration Management: – – Document preparation document maintenance change management programming tools and practices Slide 10

Slide 11 DCS and MCS Infrastructure Common Threads • Designed for flexibility, extensibility and robustness • Layered Architecture • Unix platform • CORBA middleware • Iterative Development Process • C++, Java and XML • Distributed implementation
