Pointing Angle Calculation and Aiming Accuracy Analysis of a Lunar Laser Ranging Retro-Reflector
Lunar laser ranging (LLR) has the highest precision in measuring the earth-moon distance. The lunar laser ranging retro-reflector (LRRR) is an essential piece of equipment for realizing lunar laser ranging. China has plans to deploy a manually emplaced new generation LRRR. For the LRRR to work effectively, the azimuth and altitude angle of the LRRR must be adjusted such that the LRRR is aligned with the mean Earth direction. We established a method for calculating the adjustment angle of the LRRR and analyzed the misalignment caused by the biases of emplacement time and emplacement site. Results show that the aiming of error of the LRRR can be estimated at approximately
