  2. 1. Undifferenced GPS for Deformation Monitoring

    Author : Johan Vium Andersson; Lars Sjöberg; Jonas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; Geoengineering; Geoteknik;

    Abstract : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. READ MORE

  4. 2. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Author : Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Abstract : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. READ MORE

  5. 3. Quality description in GPS precise point positioning

    Author : Masoud Shirazian; Lars Erick Sjöberg; Jan M. Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; PPP;

    Abstract : GPS processing, like every processing method for geodetic applications, relies upon least-squares estimation. Quality measures must be defined to assure that the estimates are close to reality. READ MORE

  6. 4. Sensor Fusion and Calibration of Inertial Sensors, Vision, Ultra-Wideband and GPS

    Author : Jeroen D. Hol; Thomas Schön; Fredrik Gustafsson; Bo Bernhardsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor fusion; calibration; inertial sensors; vision; UWB; GPS; Automatic control; Reglerteknik;

    Abstract : The usage of inertial sensors has traditionally been confined primarily to the aviation and marine industry due to their associated cost and bulkiness. During the last decade, however, inertial sensors have undergone a rather dramatic reduction in both size and cost with the introduction of MEMS technology. READ MORE

  7. 5. GPS/IMU Integrated System for Land Vehicle Navigation based on MEMS

    Author : Yueming Zhao; Lars Sjöberg; Milan Horemuž; Krzysztof Gajdamowicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; IMU; MEMS; integration; Kalman filter; physical constraint; outlier;

    Abstract : The Global Positioning System (GPS) and an Inertial Navigation System (INS)are two basic navigation systems. Due to their complementary characters in manyaspects, a GPS/INS integrated navigation system has been a hot research topic inthe recent decade. Both advantages and disadvantages of each individual systemare analyzed. READ MORE
