1. 1. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Renato Franze; [2023]
   Keywords : Attitude Dynamics; Attitude Control; Earth Observation; Scheduling; Attityddynamik; Attitydkontroll; Jordobservation; Uppgiftsschemaläggning;

   Abstract : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. READ MORE

3. 2. Chaos in Stellar Dynamics - Outcomes of Binary-Single interactions in Globular Clusters

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Lucas Hellström; [2020]
   Keywords : Stellar Dynamics; Binary-Single interactions; Dynamical encounters; Additional processes; Physics and Astronomy;

   Abstract : Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. READ MORE

4. 3. A Linear Framework for Orbit Correction in the High-Luminosity Large Hadron Collider

   University essay from Lunds universitet/Matematik LTH

   Author : Joel Andersson; [2019]
   Keywords : CERN; HL-LHC; LHC; accelerator physics; orbit correction; error correction; closed orbit; Twiss; beam dynamics; dynamical systems; Python; Mathematics and Statistics;

   Abstract : In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. READ MORE

5. 4. Effect of Insertion Devices Tapering Mode of Operation on the MAX IV Storage Rings

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

   Author : Georgia Paraskaki; [2018]
   Keywords : Science General;

   Abstract : Tapering is a mode of operation of insertion devices that allows the users to perform scanning in a range of photon energies. NanoMAX, BioMAX and BALDER are all beamlines of the 3 GeV MAX IV storage ring and will provide this special mode of operation for their users. READ MORE

6. 5. Robust and Agile Attitude Control for Triple CubeSat Eye-Sat

   University essay from KTH/Rymdteknik

   Author : Benjamin Charbaut; [2018]
   Keywords : ;

   Abstract : Eye-Sat is a student-designed 3U-CubeSat, to be launched to a sun-synchronous orbit from where it will map the zodiacal light, a faint glare caused by the reflection of Sun on interplanetary dust. Such mission requires an accurate 3-axis attitude control, for which Eye-Sat is equipped with reactions wheels, magnetorquers, magnetometers and a star tracker. READ MORE
