Comment on "The gravitomagnetic influence on gyroscopes and on the lunar orbit"

TL;DR

This paper argues that current lunar laser ranging technology cannot detect gravitomagnetic effects due to gauge residual freedom in relativistic lunar motion models.

Contribution

It highlights the limitations of lunar laser ranging in observing gravitomagnetic phenomena caused by gauge residual freedom.

Findings

LLR cannot currently detect gravitomagnetic effects

Gauge residual freedom affects lunar motion modeling

Current technology lacks sensitivity for gravitomagnetic detection

Abstract

Analysis of the gauge residual freedom in the relativistic theory of lunar motion demonstrates that lunar laser ranging (LLR) is not currently capable to detect gravitomagnetic effects.
