  1. 1. 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. 2. Dark Ages Lunar Interferometer - Deployment Rover : Propulsion and Steering Systems

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Victoria Birgersson; Maximillian Lundgren-Goodman; [2015]
    Keywords : NASA; DALI; rover; rymden; månen; framdrivning; styrsystem; astronomi;

    Abstract : 2030 NASA Jet Propulsion Laboratory will place an interferometer, which will workas a radio telescope, on the far side of the Moon. The interferometer uses thinpolyamide films as antennas, which are rolled out by a rover (an autonomousvehicle). The thesis covers concept generation of the propulsion and steering systemof the rover. READ MORE

  4. 3. Switching to the “Golden Age of Natural Gas” with a focus on shale gas exploitation : a possible bridge to mitigate climate change?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hossein Maazallahi; [2015]
    Keywords : Physical Geography and Ecosystem Science; GEM; shale gas exploitation; fugitive methane; climate change; carbon dioxide; age of natural gas; fossil fuel combustion; Earth and Environmental Sciences;

    Abstract : Currently, policy makers put high attention in supplying global energy demand by focusing on 2°C policy; global temperature anomaly based on the global mean temperature of pre-industrial era (13.7°C). How to keep the 2°C policy at global scope is the main question in climate framework. READ MORE

  5. 4. Kinematic orbit determination of low Earth orbiting satellites, using satellite-to-satellite tracking data and comparison of results with different propagators

    University essay from KTH/Geodesi och geoinformatik

    Author : Muhammad Zaheer; [2014]
    Keywords : GPS; Orbit Computation; STK; SGP4; HPOP;

    Abstract : The GPS data from Challenging Mini-satellite Payload (CHAMP) is used for its orbit determination for the epoch day of January 1st 2002.  The orbit of CHAMP is computed from the GPS data and ionospheric effects are removed by frequency combination. READ MORE
