1. 21. 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. 22. Avoiding the Kessler Effect : An Evaluation of the International Regulation of Space Debris

   University essay from Uppsala universitet/Juridiska institutionen

   Author : Edvin Matton; [2023]
   Keywords : space law; space debris; international state responsibility; international state liability;

   Abstract : The mass of space debris in orbit around the Earth is growing and will continue to grow due to more frequent launches of satellites and space debris colliding with other space debris. This could lead to a situation in the future where a part, or all, of the orbit becomes so crowded with space debris that it becomes impossible to launch satellites to that region. READ MORE

4. 23. Moon plasma environment and its implications for lunar space missions

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Mirko Viviano; [2023]
   Keywords : ;

   Abstract : This study investigates the lunar plasma environment and its implications for the safety and success of future crewed missions to the Moon. The Moon’splasma environment, formed by the solar wind, galactic cosmic rays and solar flare particles, presents potential hazards to human life and property. READ MORE

5. 24. Non-Disposable and Reusable Solar Sails for Transporting Sunshades to the L1' Point

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Jörgen Smit; Thomas Östervall; [2023]
   Keywords : Sunshade Project; L1; Solar sailing;

   Abstract : This study evaluates the feasibility of reusing lightweight solar sails in order to transport 1.69 * 10^6 sunshades, made out of occulting membranes with free-standing SiO2 nanotube films, to the adjusted sun-Earth Lagrange point, L1'. READ MORE

6. 25. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Clara Nermark; [2023]
   Keywords : Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

   Abstract : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. READ MORE
