When constructing any scientific theory, it is essential to have experimental evidence supporting the conclusions derived from it. In our study on the development of the theory of the Moon’s rotation, the term ‘‘experiment’’ refers to data obtained from lunar laser ranging (LLR). The article proposes a methodology for the reduction of lunar laser ranging (LLR) observational data. In the processing of LLR data 1, it is crucial to recognize that the primary observable is the time of signal emission and reception. Consequently, the connection between observations and theoretical models is established through the solution of an inverse problem.
