  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. Interference in Global Positioning System Signals and its Effect on Positioning and Remote Sensing

    Författare :Oscar Isoz; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric science;

    Sammanfattning : GPS and the other GNSS systems (GLONASS, Galileo and Beidou-2/COMPASS) is used to position billions of devices and is saving lives, the environment and money on a daily basis. GNSS enables anyone to determine their own unique global location. LÄS MER
