  1. 1. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Antoni Eritja Olivella; [2024]
    Keywords : SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Abstract : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. READ MORE

  3. 2. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gioele Daka; [2023]
    Keywords : Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

    Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE

  4. 3. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Lucian Spitzner; [2023]
    Keywords : astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Abstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

  5. 4. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Aayush Desai; [2023]
    Keywords : Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Abstract : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. READ MORE

  6. 5. Application of Discrete Time High Order Control Barrier Functions for a prototype multi-spacecraft inspection of the ISS

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

    Author : Gregorio Marchesini; [2023]
    Keywords : Space Robotics; Control Barrier Functions; Autonomous systems; Multi-agent systems;

    Abstract : In the past few years, the application of Control Barrier Functions (CBF) and High Order Control Barrier Functions (HOCBF) as a suitable framework to ensure safety for autonomous systems has attracted increasing interest. In particular, autonomous space systems are frequently subject to safety-critical constraints due to the high costs involved in manufacturing and launching. READ MORE
