Planning and scheduling for earth-observing small satellite constellations
… The first is the development of a hierarchical smallsat constellation planning and scheduling system that addresses data routing and resource management. A centralized ground-based algorithm, the Global Planner, manages the whole constellation, while an onboard algorithm, the Local Planner, …

Method and Simulation of On-Orbit Sub-microthrust Evaluation
… 10<sup>-7</sup>-10<sup>-13</sup> N, smallsat mission is explored. A detailed error analysis is conducted, and the technique is found to be analytically viable for greater than or equal to 10<sup>-7</sup> N on a 1U nanosat equipped with sun sensor and three-axis gyroscope, as well as …

Design, Analysis, Fabrication, and Testing of a Nanosatellite Structure
… industry is undergoing a transition toward "smallsat" engineering. Small satellites are becoming more attractive to customers as a method of decreasing cost. As the launch costs remain relatively constant, the industry is turning towards nano-technology, such as microelectromechanical …

Adaptive and Responsive Design Under Uncertainty for Resource-Constrained Small Satellites
… the performance sacrifice of robust design. As SmallSats continue to decrease in size - even down to the hundreds of grams - the need grows for design techniques that offer resilience under uncertainty without the inevitable sacrifice of performance that comes with robust design. In this thesis, …

Robots Making Satellites: Advancing In-Space Manufacturing Through On-Orbit Robotic Assembly
… Introducing modularized small satellites (SmallSats) for use cases such as rapid reconstitution of satellite constellation nodes and inspecting damaged assets in Low Earth Orbit (LEO) can accelerate on-orbit robotic assembly capabilities. This thesis introduces and explores the potential of …

Architecting Optimal (Space) Strategies: A Quantitative Framework
… space assets. Example scores range from 47 for a smallsat to 75 for a large geostationary satellite. Finally, the thesis proposes two network-science-based methods to help analysts and decision-makers understand the structural origins of strategic success. The first method examines how the network …

Resource optimization algorithms for an automated coordinated CubeSat constellation
… The first algorithm is the Resource-Aware SmallSat Planner (RASP), which performs low-level planning of observation and communication activities for a single satellite while simultaneously keeping the satellite's onboard resources within specified bounds. RASP utilizes a Mixed Integer …

Aerodynamic stability analysis of a CubeSat in high-speed rarefied flow
Small satellites, such as CubeSats and SmallSats, are seeing increased use in Low Earth Orbit, particularly at altitudes with measurable aerodynamic effects. It is important to design these spacecraft, which often have modest control authority, such that the resultant aerodynamic forces and moments …

FILM EVAPORATION MEMS THRUSTER ARRAY FOR MICROPROPULSION
Current small sat propulsion systems require a substantial mass fraction of the vehicle involving tradeoffs between useful payload mass and maneuverability. This is also an issue with available attitude control systems which are either quickly saturated reaction wheels or movable high drag surfaces …
