  2. 6. 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

  4. 7. GPS for Geophysics: Glacial Isostatic Adjustment and Tests of Ionospheric Models

    Author : Sten Bergstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rheology; noise; crustal deformation; horizontal movement; time series analysis; ionosphere; GPS; NeQuick;

    Abstract : This dissertation is divided into two parts that separately utilize high precision Global Positioning System (GPS) satellite observations for inferences of solid earth and ionospheric parameters.In the first part of the dissertation, solid earth movements in Sweden and Finland are observed with GPS at a precision of the order 0.1 mm/yr.

  5. 8. Remarks on the quality of GPS precise point positioning using phase observations

    Author : Masoud Shirazian; Lars E. Sjöberg; Martin Lidberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; PPP; Phase;

    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. 9. 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. 10. On GPS receiver architectures

    Author : Jonas Thor; Luleå tekniska universitet; []
    Keywords : ;

    Abstract : Navigation can be described as the art of finding the way from one location to another. Clearly navigation is something that we perform in our every day lives and the role of navigation can not be underestimated. There exist many technologies that implement various navigation systems to aid in this process. READ MORE
