1. 1. Design and Implementation of a Rocket Launcher Hybrid Navigation

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

   Sammanfattning : 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.

   Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

4. 3. 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.

5. 4. Hardware-in-the-loop simulation and testing of the ADCS of the Beyond Atlas CubeSat

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kritee Mahanti; [2021]
   Nyckelord :space; HIL; CubeSat; ADCS; satellites; rymd; HIL; CubeSat; ADCS; satelliter;

   Sammanfattning : Beyond Atlas, a company based in Danderyd, Sweden is working on a Low Earth Orbit (LEO) 3U-CubeSat (Cube Satellite) exploration mission. As part of their maiden mission, they aim to validate the navigation, propulsion, and communication techniques of a CubeSat while it performs orbital maneuvers to collect photographs of space debris.
