Description

Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on Moon since 1969. From the mesurements it is possible to estimate the Earth Rotation Parameters (ERP) using LLR data. For the determination of the published ERP data 28093 LLR normal points for the time span April 1970 - April 2021 were used. The analysis was done with the LUNAR software of the Insitute of Geodesy (IfE). The data contains 32 files which show the estimated values and their 3-sigma uncertainties of the Earth Rotation Phase (ΔUT1) and the terrestrial pole offsets (xp and yp). The data is devided in 3 subsets according to the minimum number of normal points (NPs) per night (e.g. 5, 10, or 15 NPs). Each subset contains files with ERPs calculated from NPs observed from either only APOLLO (USA), or only OCA (France), or all LLR observatories. For APOLLO, the case of 15 NPs per night was not considered. Each case has four individual files - one each for results of the estimation of ΔUT1, xp, yp, and xp & yp.
