  1. 1. Machine Learning-based MIMO Indoor Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Qiyi Chen; [2023]
    Keywords : Technology and Engineering;

    Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

  2. 2. A Modular Approach to Design and Implementation of an Active GNSS Antenna

    University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Author : Ulrik Hecktor; [2022]
    Keywords : GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

    Abstract : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. READ MORE

  3. 3. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Emma Beskow; [2022]
    Keywords : GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Abstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference.

  4. 4. RTK GNSS

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Stephanie Mirsky; [2021]
    Keywords : RTK GNSS; RTK; GNSS; NTRIP; Technology and Engineering;

    Abstract : RTK GNSS is a way of deciding the position of a GNSS receiver with high precision. It should theoretically be possible to determine the position with the precision of a couple of centimeters. Traditionally the RTK GNSS system consists of a base station and a rover. READ MORE

  5. 5. Design of Cellular and GNSS Antenna for IoT Edge Device

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Ioannis Broumas; [2019]
    Keywords : IoT; Internet of Things; Edge device; LTE; 4G; LTE-M1; Antenna; Antenna System; Narrow Band IoT; NB-IoT; Plannar Antennas; GPS; PCB; multiband antenna;

    Abstract : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. READ MORE
