  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. Utilising Raw GNSS Data from Android Units to Improve Positioning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Karin Seifert; [2022]
    Keywords : ;

    Abstract : In this study it was examined if positioning can be improved by utilising raw Global Navigation Satellite System (GNSS) data from Android devices instead of using Android's existing Location API. If this is the case, the coworkers at BM System may modify their apps, one is called Loco, to develop one that calculates positions directly by utilising raw GNSS data instead of using Android's Location API which is done presently.

  4. 3. Evaluation of airborne and marine gravity data over Kattegat region

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Chrishan Fonseka; [2020]
    Keywords : ;

    Abstract : The Kattegat sea region between Denmark and Sweden is identified as a region both economically and environmentally sensitive. Statistics indicate that over two thousand vessels per day navigate in the region. Navigation route optimization for the region is vital for efficient transportation. READ MORE

  5. 4. Deformation monitoring using GNSS:A study on a local network with preset displacements

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Peshawa Mohammed; [2019]
    Keywords : Deformation detection; processing parameters; GNSS; online post-processing;

    Abstract : In the past two decades, the number of observations and the accuracy of satellite-basedgeodetic measurements like Global Navigation satellite systems (GNSS) greatly increased,providing measured values of displacements and velocities of permanent geodetic stations.Establishment of the geodetic control networks and collecting geodetic observations, indifferent epochs, are a commonly used method for detection of displacements andconsequently disaster management.

  6. 5. A study on the quality of the NKG2015 geoid model over the Nordic countries

    University essay from Högskolan Väst/Avdelningen för Matematik, Data- och Lantmäteriteknik

    Author : Jenny Berntsson; [2019]
    Keywords : Geodesi; modell; kvalitet;

    Abstract : Geoidmodellen NKG2015 (Nordiska kommissionen för geodesi) är den senaste geoidmodellen över Norden. Det har inte publicerats någon forskning om kvaliteten på den här nya modellen, därför kan den här studien bidra till forskningen inom ämnet. READ MORE
