  • Kersten, Tobias; Ren, Le; Schön, Steffen (Noordwijk, The Netherlands : Esa ESTEC, 2018)
    Efficient and economic guidance of inland vessels relies on a continuous, available, reliable and precise GNSS navigation solution. Hence, below other side effects, this is especially critical when passing beneath bridges ...

  • Kröger, Johannes; Breva, Yannick; Kersten, Tobias; 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 ...
  • Kersten, Tobias; Kröger, Johannes; Breva, Yannick; Schön, Steffen (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    The Institut für Erdmessung (IfE) at the Leibniz University Hannover calibrates GNSS antennas determined by the well known robot based concept in the field. Our group has recently improved the calibration procedure to ...
  • Kersten, Tobias; Ren, Le; Schön, Steffen (Bonn : DGON, 2018)
    This paper describes a concept to obtain a continuous navigation and position solution of inland vessels based on a multi-GNSS antenna system. Also known as, “Virtual Receiver” we utilize this approach as an alternative ...

  • Kersten, Tobias; Kröger, Johannes; Breva, Yannick; Schön, Steffen (München : European Geosciences Union, 2019-04-08)
    Precise GNSS applications like positioning, navigation and timing (PNT) as well as troposphere studies require consistent and accurate calibration values of receiver antennas. Nowadays, they are available by several ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Schön, Steffen; Kersten, Tobias (Washington D.C. : American Geophysical Union, 2013)
    One important part for ensuring the high quality of the International GNSS Service's (IGS) products is the collection and publication of receiver - and satellite antenna phase center variations (PCV). The PCV are crucial ...
  • 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 ...
  • 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 ...
