  1. 1. Comprehensive Venus boundaries model : Empirical dependency of boundaries on the upstream conditions

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Umberto Rollero; [2023]
    Nyckelord :Bow shock; Ion Composition Boundary; Venus; Upstream conditions; Solar wind.; Bow shock; Bogshock; Ion Composition Boundary; Venus; Uppströmsförhållanden; Solvind.;

    Sammanfattning : Since Venus is an unmagnetized planet, it doesn’t interact with the solar wind in the same way as planets with an intrinsic magnetic field do. Due to its conductive ionosphere, however, it still possesses an induced magnetosphere. LÄS MER

  3. 2. Ionospheric Effect on GPS During Solar Maximum

    Magister-uppsats, KTH/Fastigheter och byggande

    Författare :Netsai Wiboonwipa; [2021]
    Nyckelord :GPS; Ionosphere; MS-TIDs; Polar cap patches; GPS; jonosfär; MS-TID; polarkåpor;

    Sammanfattning : Ionospheric effects are one of the factors that can have negative impact on Global Navigation Satellite Systems (GNSS). Those effects can be called medium-scale traveling ionospheric disturbances (MS-TIDs) at middle latitude regions and polar cap patches at high latitude regions. LÄS MER

  4. 3. A kinetic perspective of electron trapping near a weakly outgassing comet

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Chaitanya Prasad Sishtla; [2019]
    Nyckelord :;

    Sammanfattning : The European Space Agency’s Rosetta spacecraft followed the comet 67P/Churyumov-Gerasimenko from August 2014 to September 2016, providingobservations of the comet ionosphere at varying heliocentric distances. Measurementsfrom the Rosetta mission have shown a multitude of non-thermalelectron distributions in the cometary environment, challenging the previouslyassumed origin and plasma interaction mechanisms near a cometary nucleus.

  5. 4. Determination of Ion Number Density from Langmuir Probe Measurements in the Ionosphere of Titan

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för teknikvetenskaper

    Författare :Oleg Shebanits; [2010]
    Nyckelord :ion number distribution; titan; ionosphere; langmuir;

    Sammanfattning : Saturn’s largest moon, Titan, presents a very interesting subject for study because of its atmosphere’s complex organic chemistry. Processes taking place there might shed some light on the origins of organic compounds on Earth in its early days. LÄS MER
