Abstract:

Improving Small Satellite Reliability A Public-Private Initiative - Interagency SmallSat Reliability Initiative launched July 2016 Technical Interchange Meeting convened 14-15 February 2017 -One component of a public-private national initiative. Historically, it was understood and accepted that high risk and CubeSat were largely synonymous expectations were set accordingly. Their growing potential utility is driving an interagency effort to improve and quantify CubeSat reliability, and more generally, small satellite mission risk. Goals- Secure industry inputs on initial government thoughts on SmallSat mission classifications and mission assurance approaches Establish next steps. Finding Focus on Mission Confidence Levels High Confidence You want a system and execution approach that generates HIGH CONFIDENCE when It is a single vehicle that has got to work no opportunity to refly It is a multi-vehicle system that needs every vehicle to work no vehicle redundancy, no opportunity for a second launch You can achieve HIGH CONFIDENCE through various combinations of Part, component, and vehicle redundancy EEE parts selection Design practices and margins Previous flight and system experience heritage Testing HW and SW and requirements verification Spares policy Design iterations e.g. breadboards, engineering models, Qual units, flight units.
