  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. Design and Implementation of a Rocket Launcher Hybrid Navigation

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

    Author : Omar Ugolini; [2023]
    Keywords : launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Abstract : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

  4. 3. Space Rider System: GNC and System Model Improvements

    University essay from KTH/Rymdteknik

    Author : Simon Vial; [2022]
    Keywords : Space Rider System; Disturbance Modelling; Maneuver Optimization; Space Rider System; Modellering av Störningar; Manöveroptimering;

    Abstract : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. READ MORE

  5. 4. DESIGN, MODELLING AND CONTROL OF A THRUST BASED UAV

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Enrico Giacomini; [2021]
    Keywords : ;

    Abstract : The current year, 2021, started with the landing of the Perseverance mission and the flight of the first drone on Mars, marking an important event in the history of space exploration. The exploration of new environments would be easier and characterised by the absence of various obstacles if implementing a larger use of drones. READ MORE
