1. Mission Design Considerations of the Propulsion System Demonstration as part of the Hugin Space Exploration Technology Satellite Mission
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Beyond Atlas is a Swedish private company with the goal of exploring the solar system with cheap and reliable spacecraft. Part of their maiden mission, Hugin, aims to demonstrate navigation, propulsion, and communication technology on a 3U CubeSat. LÄS MER
2. Design, simulation, and testing of an electric propulsion cluster frame
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. LÄS MER
3. Further Development of a Distributed Robust Control Approach towards a Nanosatellite Formation Flying Application
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : This thesis proposes a distributed robust control approach for low-thrust nanosatellite formation flying. The presented control approach is the further development of an already existing approach which combines robust control and distributed control using the consensus approach. LÄS MER
4. Development of an Automated Test Platform for Characterization and Performance Assessment of Electronic Modules in Electric Thrusters : The TESPEMET Project
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : There has been a sharp increase in the market for electric propulsion systems for small satellites in the recent years. Electric propulsion systems have become smaller, more efficient and cheaper, which made them ideal for small satellites because they have a low thrust requirement and benefit significantly from the high specific impulse (Isp) that is characteristic to electric thrusters.

5. Networked Model Predictive Control for Satellite Formation Flying
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : A novel continuous low-thrust fuel-efficient model predictive control strategy for multi-satellite formations flying in low earth orbit is presented. State prediction relies on a full nonlinear relative motion model, based on quasi-nonsingular relative orbital elements, including earth oblateness effects and, through state augmentation, differential drag.
