  1. 6. A detailed study of auroral fragments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Joshua Dreyer; [2019]
    Keywords : aurora; fragments; Svalbard; all-sky camera; MSP; ASK; EISCAT;

    Abstract : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.

  3. 7. A statistical study of incoherent scatter plasma line enhancements during the International Polar Year ’07-’08 in Svalbard

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Michael Hammarsten; [2016]
    Keywords : Atmosphere; Ionosphere; Northen Lights; Aurora; Space Physics; Physics; EISCAT; Incoherent Scatter; Plasma;

    Abstract : There was a large radar campaign during 2007 and 2008, the International Polar Year (IPY),and at that time the EISCAT Svalbard Radar was operated and measured the ionosphere continuouslyat most times. This report presents statistical results from an electron enhancementpoint of view. READ MORE

  4. 8. Orbit Determination Analysis for SSAPurposes

    University essay from KTH/Rymd- och plasmafysik

    Author : Matteo Crimella; [2015]
    Keywords : ;

    Abstract : Space Situational Awareness (SSA) is the characterization of the space environmentand of space activities. The fundament of SSA is the access to information about theorbit of space objects. There exist several techniques to determine the orbit of objects inspace, both from space-based and from ground-based observations. READ MORE

  5. 9. Statistical Study on Langmuir Turbulence Radar Signatures Observed by the ESR

    University essay from KTH/Rymd- och plasmafysik

    Author : Alexander Karlsson; [2015]
    Keywords : ;

    Abstract : In this thesis data taken by the EISCAT Svalbard Radar during the International PolarYear have been analyzed. The radar data have been searched for anomalous radarechoes. These radar echoes appear in an altitude range between 200 and 300 km, showa strong enhancement of the backscattered power and are limited in altitude to tensof kilometers. READ MORE

  6. 10. Mutual coupling effects and optimum architecture of a sparse antenna array

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Irina Tecsor; [2013]
    Keywords : ;

    Abstract : The objective of this thesis is to investigate the performance of the EISCAT 3D Array antenna for dierent architectures and dierent types of elements. The thesis focuses on the type of element designed by Lulea Technical University and build by GELAB Company. READ MORE
