SmallSat Reliability: Issues and Solution Approaches
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).
