  1. 1. 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.

    Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Abstract : 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. READ MORE

  4. 3. Improving the guidance, navigation and control design of the KNATTE platform

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Lars Lundström; [2023]
    Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

    Abstract : 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 of MIST Attitude Determination and Control System

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

    Author : Alejandro Vicario; [2022]
    Keywords : Functional Testing; HIL; FlightSimulations; ADCS; TestManager; TestStand; Satellite subsystems; Funktionell testning; HIL; flygsimuleringar; ADCS; testledare; TestStand; satellitsub system;

    Abstract : The MIST(MIniature Student saTellite) project is a 3U CubeSat developed by student teams at KTH Royal Institute of Technology in Stockholm. One of the fundamental systems of the satellite is the Attitude Determination and Control System (ADCS), re sponsible for estimating and correcting the satellite’s orientation using magnetic fields and sun sensors.
