  • GRACE and GRACE-FO processing at IfE/LUH 
    Koch, Igor; Flury, Jakob; Duwe, Mathias; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    Updates on gravity field recovery from GRACE and GRACE Follow-On data at IfE/LUH.
  • GRACE gravity field reprocessing at IGG Bonn 
    Eicker, Annette; Kurtenbach, Enrico; Mayer-Gürr, Torsten; Shabanloui, Akbar; Kusche, Jürgen (2012-05-24)
    GRACE gravity field reprocessing at IGG Bonn
  • GRACE-FO monthly solutions using the GRACE-SIGMA software 
    Koch, Igor; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    In this contribution we present gravity field monthly solutions from GRACE Follow-On (GRACE-FO) Level-1B sensor data. The monthly solutions are computed with the GRACE-SIGMA software developed at the Institute of Geodesy, ...
  • GRACE-FO processing at IfE/LUH 
    Koch, Igor; Duwe, Mathias; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Processing strategy of the LUH-GRACE-FO-2020 monthly gravity field time series is presented. The spectral noise, spatial noise and signal content of the time series (2018-06 - 2020-08) is evaluated.
  • Influence of accelerometer parametrizations on GRACE post-fit residuals 
    Koch, Igor; Shabanloui, Akbar; Flury, Jakob (München : European Geosciences Union, 2019-04-07)
    Accelerometers onboard of satellites can be regarded as a key improvement in gravity field recovery. These instruments are located in the center of mass of the satellite and are precisely measuring non-gravitational forces ...
  • LUH-GRACE2018: A new time series of monthly gravity field solutions from GRACE 
    Koch, Igor; Naeimi, Majid; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018-10-09)
    In this contribution, we present a new time series of monthly gravity field solutions mainly obtained from GRACE K band range rate (KBRR) measurements. Our monthly solutions are computed using the in-house developed ...
  • LUH-GRACE2018: Neue Zeitreihe monatlicher GRACE-Lösungen 
    Koch, Igor; Naeimi, Majid; Flury, Jakob (2018-10-16)
    Dieser Beitrag beschäftigt sich mit einer neuen Zeitreihe monatlicher Schwerefeldlösungen aus GRACE KBRR-Beobachtungen. Diese monatlichen Lösungen wurden mittels eigener GRACE-SIGMA Software in zwei Prozessierunsschritten ...
  • Reprocessing of CHAMP and GRACE observations for the determination of improved static and temporal gravity field models with regional refinements 
    Eicker, Annette; Kurtenbach, Enrico; Mayer-Gürr, Torsten; Shabanloui, Akbar; Kusche, Jürgen (2012-05-24)
    Reprocessing of CHAMP and GRACE observations for the determination of improved static and temporal gravity field models with regional refinements
  • Signals of Geophysical Nature in GRACE and GRACE-FO Post-Fit Range-Rate Residuals 
    Koch, Igor; Duwe, Mathias; Flury, Jakob; Fletling, Nina (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Post-fit residuals of satellite-to-satellite tracking measurements of the GRACE and GRACE-FO missions obtained after a common estimation of orbit and gravity field parameters should ideally contain measurement noise with ...
  • Spectral analysis of residual GRACE and GRACE-FO range accelerations 
    Koch, Igor; Duwe, Mathias; Flury, Jakob (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    GRACE and GRACE-FO K-band range-rate post-fit residuals obtained after a common estimation of monthly gravity field coefficients and ancillary satellite parameters represent a complex superposition of different effects. ...
