1. 1. Improving the guidance, navigation and control design of the KNATTE platform

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Lars Lundström; [2023]
   Nyckelord :Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Sammanfattning : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

3. 2. Further Development of a Distributed Robust Control Approach towards a Nanosatellite Formation Flying Application

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Johannes Dauner; [2020]
   Nyckelord :NetSat; CubeSat; Nanosatellite; Satellite Formation; Control; Robust Control; Distributed Control;

   Sammanfattning : 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. 3. Development and Implementation of a Mass Balancing System for CubeSat Attitude Hardware-in-the-Loop Simulations

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Guillermo Ledo López; [2019]
   Nyckelord :hil; hardware in the loop; simulation; satellite; simulator; platform; simulink; matlab; least squares; aocs; testing; attitude; dynamics; control;

   Sammanfattning : Spacecraft simulator platforms can simulate the microgravity environment of space on Earth, for the purposes of testing the Attitude and Orbit Control Subsystem of satellites. In order to do this, the satellite is mounted on a bench and the combined center of mass of this assembly is controlled by a series of moving masses. LÄS MER

5. 4. Non-linear Model Predictive Control for space debris removal missions

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Alexander Korsfeldt Larsén; [2018]
   Nyckelord :;

   Sammanfattning : The rapidly increasing amounts of space debris orbiting Earth is threatening to reach a critical level, where the near-Earth environment becomes so overfilled with junk that many missions simply become unfeasible. Long-term active debris removal operations appear to be a necessity, but due to the scale of the problem this will likely be an expensive affair spanning decades or even centuries. LÄS MER

7. 5. Flight Dynamics Modelling and Application to SatelliteDeorbitation Strategy

   Master-uppsats, KTH/Flygdynamik

   Författare :Ulysse Marguery; [2011]
   Nyckelord :;

   Sammanfattning : In this paper a study to determine the best strategic choice to deorbit satellites incase of system failures is conducted. An orbital mechanic analysis of the deorbitationis done and a matlab code based on Lagrange’s interplanetary equations is developed. LÄS MER
