  • Bestimmung und Validierung von Phasenzentrumskorrektionen für Multi-GNSS-Signale 
    Kröger, Johannes; Breva, Yannick; Kersten, Tobias; Schön, Steffen (Stuttgart : Frontiers of Geodetic Science, 2019-09-17)
    Eine genaue Positionsbestimmung mittels GNSS basiert auf einem präzisen Signalempfang. Im Falle von Trägerphasenmessung stellt ein gleichförmiger Kugelstrahler eine ideale Empfängerantenne dar. Abweichungen von dieser ...
  • Codephase center corrections for multi GNSS signals and the impact of misoriented antennas 
    Breva, Yannick; Kröger, Johannes; Kersten, Tobias; Schön, Steffen (Vienna, Austria : European Geophysical Union (EGU), 2020)
    In absolute positioning approaches, e.g. Precise Point Positioning (PPP), antenna phase center corrections (PCC) have to be taking into account. Beside PCC for carrier phase measurements, also codephase center corrections ...
  • Determination of Phase Center Corrections for Galileo Signals 
    Kröger, Johannes; Breva, Yannick; Kersten, Tobias; Schön, Steffen (Zürich : European Space Agency (ESA) and ETH Zürich, 2019-09-04)
    GNSS are widely used for positioning, navigation and timing (PVT). The quality of results depends on the antenna in use and the capability to take antenna specific effects into account. The most prominent corrections are ...
  • Estimation and validation of receiver antenna codephase variations for multi GNSS signals 
    Breva, Yannick; Kröger, Johannes; Kersten, Tobias; Schön, Steffen (Zürich : European Space Agency (ESA) and ETH Zürich, 2019-09-04)
    Besides antenna phase center corrections (PCC) for carrier phase measurements, which have to be considered for precise GNSS application, also codephase variations (CPV) exist. These are antenna dependent delays of the code ...
  • GPS code phase variations (CPV) for GNSS receiver antennas and their effect on geodetic parameters and ambiguity resolution 
    Kersten, Tobias; Schön, Steffen (Berlin Heidelberg : Springer, 2017)
    Precise navigation and geodetic coordinate determination rely on accurate GNSS signal reception. Thus, the receiver antenna properties play a crucial role in the GNSS error budget. For carrier phase observations, a spherical ...
  • Impact of antenna phase center models: From observation to parameter domain 
    Kersten, Tobias; Hiemer, Leonard; Schön, Steffen (Prague : IUGG, 2015-06-25)
    For precise GNSS applications like positioning, navigation and timing (PNT) as well as for troposphere studies, stable and accurate calibrations of the carrier phase center variations (PCV) for individual antennas have to ...
  • Konzept und Analyse von Codephasenvatiationen für Multi-GNSS-Signale 
    Breva, Yannick; Kröger, Johannes; Kersten, Tobias; Schöne, Steffen (Stuttgart : Frontiers of Geodetic Science, 2019-09-19)
    Für hochpräzise GNSS-Anwendungen sind Trägerphasenmessungen unabdingbar. Bei solchen Messungen ist es notwendig die individuellen Antennenphasenzentrumskorrekturen (PCC) zu berücksichtigen. Ähnliche Korrekturen existieren ...
  • Multi-GNSS Receiver Antenna Calibration 
    Kröger, Johannes; Kersten, Tobias; Breva, Yannick; Schön, Steffen (Copenhagen : Fédération Internationale des Géométres, 2020)
    Global Navigation Satellite Systems (GNSS) are not only widely used for precise positioning, navigation and timing but also for establishing of terrestrial reference frames for geospatial applications, such as land and ...
  • Phase Center Corrections for new GNSS-Signals 
    Kröger, Johannes; Breva, Yannick; Kersten, Tobias; Schön, Steffen (2019-04-09)
    Phase center corrections (including corrections for phase center offset and phase center variations) are nowadays mandatory for high accuracy GNSS applications. Currently, only L1- and L2 frequencies for GPS and GLONASS ...
  • Validation of Phase Center Corrections for new GNSS-Signals obtained with absolute antenna calibration in the field 
    Breva, Yannick; Kröger, Johannes; Kersten, Tobias; Schön, Steffen (2019-04-09)
    For high accuracy GNSS applications it is necessary to take phase center corrections (PCC) into account. At the moment PCC from chamber calibrations for various signals are available, however GPS L5 as well as Galileo PCC ...
