  2. 16. 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.

  4. 17. Topics in Localization and Mapping

    Author : Jonas Callmer; Fredrik Gustafsson; Bo Bernhardsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor fusion;

    Abstract : The need to determine ones position is common and emerges in many different situations. Tracking soldiers or a robot moving in a building or aiding a tourist exploring a new city, all share the questions ”where is the unit?“ and ”where is the unit going?“. This is known as the localization problem. READ MORE

  5. 18. State estimation with auto-calibrated sensor setup

    Author : Sandipan Das; Saikat Chatterjee; Isaac Skog; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Sensor calibration; Autonomous driving; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Localization and mapping is one of the key aspects of driving autonomously in unstructured environments. Often such vehicles are equipped with multiple sensor modalities to create a 360o sensing coverage and add redundancy to handle sensor dropout scenarios. READ MORE

  6. 19. Enabling hardware technology for GNSS software radio research

    Author : Marcus Junered; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Software Defined Radio (SDR), has become an increasingly popular alternative to traditional radio technology. In principle the incoming radio frequency signal is sampled as close to the antenna as possible to minimize noise, distortion and other hardware related effects which degrade the signal quality.

  7. 20. Detail Surveying with GPS

    Author : Kjell Almgren; Lars Sjöberg; []
    Keywords : ;

    Abstract : Abstract In the past ten years, the Global Positioning System (GPS) has revolutionized navigation and positioning at or near the surface of the Earth. Even though it is developed and authorized by the US military forces, it has found a remarkable civilian use. In most uses of GPS, the position accuracy is in the order of metres. READ MORE
