  • Benefit of new high-precision llr data for the determination of relativistic parameters 
    Biskupek, Liliane; Müller, Jürgen; Torre, Jean-Marie (Basel : MDPI AG, 2021)
    Since 1969, Lunar Laser Ranging (LLR) data have been collected by various observa-tories and analysed by different analysis groups. In the recent years, observations with bigger telescopes (APOLLO) and at infra-red wavelength ...
  • Equivalence of Active and Passive Gravitational Mass Tested with Lunar Laser Ranging 
    Singh, Vishwa Vijay; Müller, Jürgen; Biskupek, Liliane; Hackmann, Eva; Lämmerzahl, Claus (College Park, Md. : APS, 2023)
    Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on the Moon since 1969. In this Letter, we study the possible violation of the equivalence of passive and active gravitational ...
  • Estimation of Earth Rotation Parameter UT1 from Lunar Laser Ranging Observations 
    Biskupek, Liliane; Singh, Vishwa Vijay; Müller, Jürgen (Berlin ; Heidelberg : Springer, 2022)
    Since 1969 Lunar Laser Ranging (LLR) data have been collected by different observatories and analysed by various analysis groups. LLR is providing the longest time series of any space geodetic technique for studying the ...
  • Impact of non-tidal station loading in LLR 
    Singh, Vishwa Vijay; Biskupek, Liliane; Müller, Jürgen; Zhang, Mingyue (Amsterdam [u.a.] : Elsevier Science, 2021)
    Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on Moon since 1970. In this paper, we study the effect of non-tidal station loading (NTSL) in the analysis of LLR data. ...
