dc.description.abstract Small spacecraft such as CubeSats are being used to accomplish increasingly complex missions requiring precise relative positioning and maneuverability. This capability is often provided by cold gas propulsion systems, many of which use a two phase propellant. These systems have the benefit of being simple and inexpensive, but their capabilities are limited by the current technology. There is a need for a next generation of cold gas propulsion systems that are capable of improved performance relative to the heritage systems. This paper outlines the propulsion needs of future CubeSat missions, describes the shortcomings of current systems, and proposes a design concept for the next generation of cold gas propulsion units for use on small spacecraft missions. The key areas for improvement are identified as propellant management, temperature compensation, manufacturing, leak mitigation, and reliability. The proposed next-generation propulsion system, referred to as GTCG2, aims to improve in these areas through the use of advanced additive manufacturing, a novel propellant management system, closed-loop temperature control, and redundancy of key components. This architecture will allow for increased reliability, repeatability of impulses, and impulse density while maintaining a low cost.
