    • FPGA-based data acquisition system for GNSS receiver for LEO-satellites applications 

      Siboniyo, Didier (Master thesis; Mastergradsoppgave, 2017-06-12)
      The modern Low Earth Orbit satellites (LEO-satellites) technology is highly complex and reliable than it was yesterday. Nowadays, the LEO-satellites applications extend from civilian to military applications. However, LEO-satellites require a Global Navigation Satellite System (GNSS) service, to achieve various tasks which require positioning and localizing. The challenge is to have a GNSS receiver ...

    • FPGA-based tracking system for GNSS receivers 

      Manandhar, Anil (Master thesis; Mastergradsoppgave, 2017-06-12)
      This report presents the design and simulation of code and carrier tracking system for a GNSS receiver. The GNSS receiver processes the signal sent by satellites in space. These signal contain carrier wave signal, ranging code and navigation data in encrypted form. To demodulate the navigation data, the processing block should accurately track the phase of incoming code and the frequency of incoming ...

    • Stabilitet i 22kV distribusjonsnett 

      Skogvoll, Petter (Master thesis; Mastergradsoppgave, 2017-05-18)
      De senere årene har det vært en økning i utbygging av små produksjonsenheter i distribusjonsnettet. I dag benyttes distribusjonsnettet i hovedsak til å fordele kraft fra overliggende nett. En tilknytning av ny produksjon i slike nett vil medføre utfordringer for netteier når det gjelder spenningskvalitet og leveringssikkerhet og krever ofte oppgraderinger for å kunne opprettholde stabil og sikker ...

    • Optimal placement of PMUs considering logical topology of communication medium power system observability 

      Nikumbh, Bhushan Madan (Master thesis; Mastergradsoppgave, 2016-11-07)
      A phasor measurement unit (PMU) has a unique ability of providing synchronized phasor measurements of voltage and currents. This ability distinguishes it from all other metering devices. It has been perceived that PMUs hold the capability of revolutionizing the way of power system monitoring and control. However, high per unit cost and challenges related to its communication system has made ...

    • Communication in microgrids and virtual power plants 

      Starynets, Oleksandr (Master thesis; Mastergradsoppgave, 2016-11-07)
      One of the cornerstones of the steady operation of microgrids and virtual power plants as building blocks for smart grid is the communication system, which is the main objective for evaluation and research in this thesis. The given project investigates the most widespread communication protocols along with IEC 61850 standard for substations automation applied in smart grids. Based on the presented ...

    • Solar panel tracking control. Tracking the variations caused due to reflection from snow and other factors 

      Pandey, Saroj (Master thesis; Mastergradsoppgave, 2016-11-07)
      This report presents the design and simulations of a dual-axis solar tracker. This solar tracker works solely based on the output power of the PV panel mounted to it. It does not use any photosensors to orient the PV module. Describing the process in short, the position of the Sun is first calculated based on time and location information. Since this solar panel will be mounted here at UiT, ...

    • Quadrotor modeling and control 

      Kristiansen, Stig Espen (Master thesis; Mastergradsoppgave, 2016-11-03)
      In this thesis a mathematical quadrotor model based on cascade modeling theory, using a passivity-based control solution is derived and presented. The rotation and translation cascades are rst decoupled, modeled mathematically and simulated separately to test individual control solutions and stability, followed by total system modeling and simulations to verify the control solutions and stability ...

    • Ku-band patch antenna design 

      Johansen, Martin (Master thesis; Mastergradsoppgave, 2016-11-03)
      The market for on-the-move satellite communication is increasing, and phased array antennas have characteristics that makes them suited for this. In this thesis design and tuning of a wide-band microstrip patch antenna element for a Ku-band antenna array is presented. The SSFIP structure with a resonating aperture is used for the antenna element, and double resonance allows for operation at both ...
