We develop a relativistic treatment of interference between light reflected from a falling cube retroreflector in the vertical arm of an interferometer, and light in a reference beam in the horizontal arm. Coordinates that are nearly Minkowskian, attached to the falling cube, are used to describe the propagation of light within the cube. Relativistic effects such as the dependence of the coordinate speed of light on gravitational potential, propagation of light along null geodesics, relativity…

Comparison of Open and Solid Falling Retroreflector Gravimeters
We study whether the optical properties of a solid glass retroreflector influence the value of the acceleration of gravity $g$ determined by dropping both solid and open retroreflectors in an
Relativistic theory of the falling cube gravimeter ∗
In the subject paper [1] of the comment [2], light propagation through an absolute gravimeter was analyzed, including the propagation delay through the falling retroreflector and through the vacuum.
Use of the relativistic phase-time equation in absolute ballistic gravimetry
The signal recorded in absolute ballistic gravimeters and used to track the trajectory of the free-falling corner-cube was recently studied for the first time in full agreement with relativistic
No correction for the light propagation within the cube: comment on ‘Relativistic theory of the falling retroreflector gravimeter’
Although the equation of motion developed in the paper (Ashby 2018 Metrologia 55 1) depends on the parameters of the falling cube, such as depth and refraction index, the parameters are only

Comment on ‘Relativistic theory of the falling retroreflector gravimeter’
In the paper by Ashby (2018 Metrologia 55 1?10) the correction due to the time delay of light propagated through the prism retroreflector of absolute gravimeters is discussed. Accordingly, the
Reply to ‘No correction for the light propagation within the cube: Comment on Relativistic theory of the falling cube gravimeter’

On the effect of the light propagation within the corner-cube reflector of absolute gravimeters
We have assessed the implications of the in-cube light propagation effect in absolute gravimeters, and found it contradictory to existing theoretical and experimental data. We maintain that the
Systematic errors in high-precision gravity measurements by light-pulse atom interferometry on the ground and in space
We focus on the fact that light-pulse atom interferometers measure the atoms' acceleration with only three data points per drop. As a result, the measured effect of the gravity gradient is

TLDR
The generalized Fermi frame for a system of two bodies revolving in circular orbits around a common barycenter is discussed more rigorously, and it is shown that the main relativistic effects on an Earth satellite are due to the nonlinear correction in the Earth's own Schwarzschild field.
Celestial coordinate reference systems in curved space-time
In the weak-field and slow-motion approximation of the General Relativity theory the relativistic theory of construction of nonrotating harmonic coordinate reference systems is developed. The general
Correction due to finite speed of light in absolute gravimeters
TLDR
It is found that the correction derived from the Doppler effect is accountable only for 23 of the total correction due to finite speed of light, if no signal delays are considered and another major source of inconsistency was found in the tacit use of simplified trajectory models.
Inertial and gravitational effects in the proper reference frame of an accelerated, rotating observer

TLDR
The design improvements incorporated in a new generation of absolute gravimeters, the FG5, have led to an instrumental uncertainty estimate of 1,1 × 10-8 m s-2 (1,0 μGal).
