  1. 1. Space Situational Awareness with the Swedish Allsky Meteor Network

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Simon Alinder; [2019]
    Nyckelord :SSA; space situational awareness; IOD; initial orbit determination; orbit determination; satellite identification; all-sky; rymdlägessituation; SSA; omloppsbana; banbestämning;

    Sammanfattning : This thesis investigates the use of the Swedish Allsky Meteor Network (SAMN) for observing, identifying, and determining the orbits of satellites. The overall goal of this project is to determine the feasibility of using such a network for Space Situational Awareness (SSA) purposes, which requires identification and monitoring of objects in orbit.

  3. 2. Effect of the convective electric field on the ion number density around a low activity comet

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Simon Alinder; [2017]
    Nyckelord :;

    Sammanfattning : Vigren et al. (2015) presents an integral expression to calculate the ion number density around a low activity comet immersed in the solar wind's convective electric field. A certain parameter of the integral takes values of either 1 or 0 depending on whether a corresponding ion trajectory is feasible or not. LÄS MER

  4. 3. Electron cooling in a cometary coma

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Simon Alinder; [2017]
    Nyckelord :Comet; Plasma; Inner coma;

    Sammanfattning : The ESA Rosetta spacecraft investigated comet 67P/Churyumov-Gerasimenko duringtwo years from August 2014 to the end of September 2016. The dual Langmuir probewas used to measure plasma parameters including the thermal energy of theelectrons. LÄS MER
