  • Comparing GRACE Follow-On Inter-Satellite Pointing Angles from Star Camera and LRI Fast Steering Mirror 
    Müller, Laura (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023-07-26)
    The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission is observing the time variable gravity field by measuring distance variations between two satellites. The first Laser Ranging Interferometer (LRI) ...
  • 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-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.
  • Instrument data simulations for GRACE Follow-on: Observation and noise models 
    Darbeheshti, Neda; Wegener, Henry; Müller, Vitali; Naeimi, Majid; Heinzel, Gerhard; Hewitson, Martin (Göttingen : Copernicus GmbH, 2017)
    The Gravity Recovery and Climate Experiment (GRACE) mission has yielded data on the Earth's gravity field to monitor temporal changes for more than 15 years. The GRACE twin satellites use microwave ranging with micrometre ...
  • 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. ...
