  1. 1. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Author : Jessica Ye; Johan Lesko; [2023]
    Keywords : ;

    Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE

  3. 2. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Nathan Groisne; [2023]
    Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Abstract : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. READ MORE

    Abstract : The international communities of user interface, user experience and interaction designers are in an increasing need of considering Chinese users’ experiences when designing websites. China, along with other mandarin speaking populations, consists of a huge market. READ MORE

  5. 4. Spatial Variability in the Ionosphere and GNSS Signal Delays in the L-band: A Direct Comparison of In-Situ Satellite- and Swepos-Data

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

    Author : Oscar Suneson; [2021]
    Keywords : fysik; jonosfären; GNSS; GPS; astrofysik; navigationssystem; mätteknik;

    Abstract : It has been shown that ionospheric irregularities can disturb our GNSS (Global Navigation Satellite System) communication. This disturbance is caused by scintillation of the radio signals when they pass through the ionosphere, leading to lock-on difficulties or in worst case, a loss of position for the GNSS-receiver.
