Commercialization of Deployable Space Systems' roll-out solar array (ROSA) technology for Space Systems Loral (SSL) solar arrays

Deployable Space Systems (DSS) developed an advanced flexible blanket ROSA that provides ultra-low weight, compact stowage volume, high power capability, power modularity, scale-ability, and affordability. Recent NASA and AFRL programs have helped advance the ROSA solar array to Technology Readiness Level (TRL) 6. Space Systems Loral (SSL) has selected this technology for commercial qualification and infusion. SSL is currently developing and qualifying ROSA technology as part of a next generation power generating system for future geosynchronous (GEO) spacecraft, advanced NASA and DOD missions. The generic benefits (vs. standard rigid array technology) of adopting a flexible blanket solar array for the GEO application will be presented. An overview of the SSL ROSA qualification program will be presented in combination with relevant design modeling, key analysis, hardware build, validation testing tests performed to date, and next steps for implementation.
