DESCRIPTION:Speakers: Sphumelele Ndlovu (Hartebeesthoek Radio Astronomy Ob
 servatory:Space Geodesy)\nThe HartRAO Lunar Laser Ranger (LLR) system requ
 ires a state-of-the-art software tool that enables optimal efficiency and 
 signal path parameter estimation. The existing link budget equation estima
 tes the number of return photons for given conditions and LLR system param
 eters.  This equation is one of the essential mathematical tools that can 
 be considered when developing an integrated system and model for the LLR. 
 The mathematical tool\, still under development at HartRAO\, can be used t
 o estimate and visualise the relationship between the returned number of p
 hotons (observed and computed) and the varying link budget equation parame
 ters. In this work\, it is used to indicate “worse and best” parameter
  values which influence the return signal\, presented as an estimate of ex
 pected number of returned photons for the HartRAO station. This is all don
 e to achieve optimal efficiency in the LLR signal path in order to yield a
 n improvement in the return-energy of the laser so that ranges to the corn
 er cube retro-reflectors can be measured accurately. The geographic positi
 on of the HartRAO station\, new state-of-the-art HartRAO LLR system under 
 development and the expected number of returned photons will enable HartRA
 O to play a key role in improving the ranging accuracy to a sub-centimetre
  level. This will enhance the current effort to determine highly accurate 
 Earth-Moon distances for various scientific purposes.\n\nhttps://events.sa
