1. 1. Localization of eNodeBs with a Large Set of Measurements from Train Routers

   Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Författare :Simon Sundberg; [2019]
   Nyckelord :Localization; Positioning; LTE; eNodeB; base stations; Received Signal Strength; RSS;

   Sammanfattning : This master thesis investigates the possibility of locating LTE base stations, known as eNodeBs, using signal measurements collected by routers on trains. Four existing algorithms for transmitter localization are adopted: the centroid, strongest signal, Monte Carlo path loss simulation and power difference of arrival (PDoA) methods. LÄS MER

3. 2. GNSS Interference Localization Through PDOA-Methods

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Max Nyström; [2017]
   Nyckelord :GPS; GNSS; PDOA;

   Sammanfattning : As GPS signals are of low power, the receiving end is always highly susceptible to interference, both unintentional and deliberate. As such there is a need to develop practical ways of detecting and localizing interference sources. LÄS MER

4. 3. Crowdsourcing GNSS Jamming Detection and Localization

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Luka Strizic; [2017]
   Nyckelord :gnss; gps; galileo; glonass; beidou; crowdsourcing; smartphones; android; e911; j911; jamming; jammer; detection; localization; pdoa; tdoa;

   Sammanfattning : Global Navigation Satellite Systems (GNSS) have found wide adoption in various applications, be they military, civilian or commercial. The susceptibility of GNSS to radio-frequency interference can, thus, be very disruptive, even for emergency services, therefore threatening people's lives. LÄS MER
