  1. 1. An Infrared Stellar Thermometer

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Ieva Puspure; [2021]
    Keywords : Infrared Spectroscopy; Infrared; Red giants; Stellar Temperature; Spectroscopy; Physics and Astronomy;

    Abstract : Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researched.

  3. 2. Space Situational Awareness with the Swedish Allsky Meteor Network

    University essay from Uppsala universitet/Observationell astrofysik

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

    Abstract : 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.

  4. 3. 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.

  5. 4. GNSS Timing Receiver Performance in Urban Canyons

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xiangcheng Fu; [2019]
    Keywords : GNSS Timing Receiver; 1PPS; Synchronization; Urban Canyon;

    Abstract : Time synchronization is critical for the operation of radio base stations (RBS) in telecommunication companies. Global navigation satellite system (GNSS) is an existing technology to provide precise timing information to distributed RBSs. READ MORE

  6. 5. Daylight prediction based on the VSC - DF relation

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ance Olina; Nevila Zaimi; [2018]
    Keywords : Vertical Sky Component; Daylight Factor; building typology; Radiance simulations; Earth and Environmental Sciences;

    Abstract : In 2017, 255 of Sweden's 290 municipalities reported a shortage of residential housing (Boverket, 2017). The answer is to build more. Due to urbanization pressure, concerns for saving valuable agricultural land, growing national and EU demands on energy-efficiency, there is an increasing number of new and dense urban developments.
