  1. 1. Evaluation of the auroral large imagining system for automatic space debris detection

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Pulmu Pietikäinen; [2023]
    Keywords : Space debris; optical system; auroral imager;

    Abstract : The performance of the auroral large imagining system (ALIS_4D) and an automatic track detection algorithm was evaluated for space debris surveillance and tracking. The evaluation of the ALIS_4D was done through a numerical simulation and data annotations, while the track detection results were manually evaluated. READ MORE

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

    Author : Kenny Andersson; [2023]
    Keywords : space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Abstract : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. READ MORE

  4. 3. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  5. 4. Methods for Co-Orbital Threat Assessment in Space

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

    Author : Mathias Dahlman; [2023]
    Keywords : threats in space; threat assessment; Lambert s problem; genetic algorithms; NSGA-II; space surveillance and tracking capabilities; hot i rymden; hotbedömning; Lamberts problem; genetiska algoritmer; NSGA-II; inmätning och övervakning av rymdobjekt;

    Abstract : This study investigates methods for assessing threats in space. Space services are crucial to both civilian and military capabilities, and a loss of such systems could have severe consequences. Space systems are exposed to various types of threats. READ MORE

  6. 5. Feasibility study of initial orbit determination with open astronomical data

    University essay from KTH/Fysik

    Author : Linn Mattsson; [2022]
    Keywords : Space situational awareness; Space surveillance and tracking; Image analyse; Streak detection algorithm; Initial orbit determination; Rymdlägesbild; Bildanalys; Algoritm för streck detektering; Initial banbestämning;

    Abstract : In this report I present a feasibility study of using open astronomical data to make Initial Orbit Determination (IOD) for Resident Space Objects (RSO) appearing as streaks in telescope images. The purpose is to contribute to Space Surveillance and Tracking (SST) for maintaining Space Situation Awareness (SSA). READ MORE
