  1. 1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  3. 2. Integration of a Software-Defined Baseband for Nano Satellites

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

    Author : Petter Lindberg; [2022]
    Keywords : ;

    Abstract : The number of Nano satellites launched into space is increasing rapidly each year. All satellites need a ground station with a baseband to communicate with. Current commercial basebands for TT&C (telemetry, tracking and command) are using proven designs and are too expensive to be used for Nano satellites. READ MORE

  4. 3. Estimation of satellite orbits using ground based radar concept

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Gabrielsson; [2021]
    Keywords : ;

    Abstract : Today an abundance of objects are circulating in earth captured orbit. Monitoring these objects is of national security interest. One way to map any object in orbit is with their Keplerian elements. A method for estimating the Keplerian elements of a satellite orbit simulating a ground based radar station has been investigated.

  5. 4. Analysis of coastal erosion between different flights of UAV

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Zhengran Yin; [2021]
    Keywords : Coastal erosion; UAV; Digital Surface Model; Slope; Elevation differences; Geomatics; Earth and Environmental Sciences;

    Abstract : More than 600 million people are living in coastal areas in the world. According to the trend of population migration, the global coastal area population may increase to more than 1 billion by 2050. READ MORE

  6. 5. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lone Mokkenstorm; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Early Warning; Riverine Floods; Humanitarian Work; Impact-based Forecasting; Malawi; Earth and Environmental Sciences;

    Abstract : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.
