  1. 1. GNSS hardware biases in code and carrier phase observables

    Författare :Martin Håkansson; Milan Horemuz; Anna B. O. Jensen; Lambert Wanninger; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS; GNSS positioning; hardware biases; phase biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; satellite dependency; characterization; android; mass market; Group delay variations; nadir dependence; ionosphere modeling; ionospheric tomography; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

    Sammanfattning : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. The presence of biases in GNSS observations might affect the accuracy in precise GNSS positioning applications, and might also be of relevance in other GNSS applications. LÄS MER

  2. 2. Hardware biases and their impact on GNSS positioning

    Författare :Martin Håkansson; Anna B. O. Jensen; Milan Horemuz; Jan Johansson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; GNSS positioning; Hardware biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. These biases influence the accuracy in precise GNSS positioning if not handled properly. LÄS MER

  3. 3. Development of functional asymmetries in young infants : A sensory-motor approach

    Författare :Erik Domellöf; Louise Rönnqvist; Jacqueline Fagard; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Laterality; development; handedness; human infant; stepping response; placing response; head turning; arm movement; reaching; kinematic parameters; intralimb coordination; Psychology; Psykologi;

    Sammanfattning : Human functional laterality, typically involving a right-sided preference in most sensory-motor activities, is still a poorly understood issue. This is perhaps particularly true in terms of what underlying mechanisms that may govern lateral biases, as well as the developmental origins and course of events. LÄS MER

  4. 4. Arctic clouds - interactions with radiation and thermodynamic structure

    Författare :Joseph Sedlar; Michael Tjernström; Annica Ekman; Johannes Verlinde; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arctic; stratus; radiation; thermodynamic structure; cloud radiative forcing; seasonal transition; Meteorology; Meteorologi; Atmospheric Sciences; atmosfärvetenskap;

    Sammanfattning : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. LÄS MER

  5. 5. Growth and Characterisation of Non-linear Ferroelectric Heterostructures

    Författare :Khaled Khamchane; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : High dielectric constant or ferroelectric materials are needed for a range of devices, non-volatile ferroelectric computer memories, NVFRAMs, microwave devices utilising the non-linear polarisation as a function of electric field, or other microwave applications. High dielectric constant and low losses can be achieved in single crystals of ferroelectrics. LÄS MER
