  1. 16. Optical Navigation for Autonomous Approach of Unexplored Small Bodies

    University essay from KTH/Rymdteknik

    Author : Jacopo Villa; [2020]
    Keywords : Small Bodies; Asteroids; Comets; Autonomy; SLAM; Mapping; Navigation; Orbit Determination; Astrodynamics; Computer Vision; Feature Tracking; Små Kroppar; Asteroider; Kometer; Autonomi; SLAM; Kartläggning; Navigering; Omloppsbestämning; Astrodynamik; Computer Vision; Feature Tracking;

    Abstract : This thesis presents an autonomous vision-based navigation strategy applicable to the approach phase of a small body mission, developed within the Robotics Section at NASA Jet Propulsion Laboratory. Today, the operations performed to approach small planetary bodies are largely dependent on ground support and human decision-making, which demand operational complexity and restrict the spectrum of achievable activities throughout the mission.

  3. 17. Range-based Wireless Sensor Network Localization for Planetary Rovers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : August Svensson; [2020]
    Keywords : SLAM; Sensor Networks; Interplanetary Rovers; Space Exploration; Simulation;

    Abstract : Obstacles faced in planetary surface exploration require innovation in many areas, primarily that of robotics. To be able to study interesting areas that are by current means hard to reach, such as steep slopes, ravines, caves andlava tubes, the surface vehicles of today need to be modified or augmented.

  4. 18. Towards Realizing Digital Voting: Assessing Readiness of Blockchain Enabled Voting

    University essay from Luleå tekniska universitet/Digitala tjänster och system

    Author : Elias Lundmark; Jan Niia; [2020]
    Keywords : E-voting; Digital voting; Blockchain; Blockchain enabled voting; Technology readiness;

    Abstract : Voting and general elections serves as a cornerstone of modern democracies as it is through this process that the public makes their political positions heard and collectively elect leaders. While many parts of governments across the world are focusing heavily on digitization, voting is one area that remains offline and analog in many developed countries. READ MORE

  5. 19. High resolution imaging observations of exoplanet host stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Kaltrina Kajtazi; [2020]
    Keywords : Speckle imaging; Speckle interferometry; High resolution imaging; Short integration time; Binaries; Exoplant hosts; Stellar properties; WIYN; Gemini; Orbital period; Physical separation; Angular separation; magnitude difference; Physics and Astronomy;

    Abstract : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. READ MORE

  6. 20. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE
