  • 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 ...
  • Schilling, Manuel; Schlippert, Dennis; Schubert, Christian; Wodey, Etienne; Meiners, Christian; Ertmer, Wolfgang; Rasel, Ernst Maria; Müller, Jürgen (Washington D.C. : American Geophysical Union, 2016-12-12)
    A large variety of scientific experiments as well as common applications require more and more precise knowledge of gravity g, its derived quantities, and their change in time. For several phenomena the effect on g can be ...
  • Timmen, Ludger; Kersten, Tobias; Müller, Jürgen; Schilling, Manuel; Schön, Steffen; Paffenholz, Jens-André; Neumann, Ingo (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2018)
    Das HITec ist für die Wissenschaft der Geodäsie und der Physik eine weltweit einzigartige Laborumgebung. Dort soll durch die Simulation verschiedenster Umweltbedingungen die Entwicklung von MultiSensorSystemen (MSS) der ...
  • 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 ...
  • Schnatz, Harald; Paschke, Anna-Greta; Schmidt, Piet O. (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2018)
    Im HITec arbeiten Geodäten und Physiker der Leibniz Universität Hannover (LUH) zusammen mit Wissenschaftlern der Physikalisch-Technischen Bundesanstalt (PTB) unter anderem daran, optische Uhren und deren Vergleiche für ...
  • 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 ...
  • Krawczyk, Charlotte; Dahm, Thorsten; Gabriel, Gerald; Polom, Ulrich; Becker, Dirk; Schön, Steffen; Kersten, Tobias; Timmen, Ludger; Weise, Adelheid; Werban, Ulrike; Kaufmann, Georg; Börner, Frank; Mai, Franziska; Romanov, Douchko; Schuck, Andreas (Hannover : Technische Informationsbibliothek Hannover, 2019-06-30)
    Das Verbundprojekt SIMULTAN erforscht die Früherkennung für Instabilität, Unruhe und Kollaps von Erdfällen. Der neuartige Forschungsansatz kombiniert strukturelle, geophysikalische, petrophysikalische und hydrologische ...
