  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. The resulting expression for the
interference signal applies without any subsequent "speed-of-light" correction.
Other corrections appeared for the three fitting parameters $Z_0,\ V_0$ and
$g$, which are the initial position and velocity, and the acceleration of
gravity at the reference point. The comment assumes the value of $Z_0$ is known
apriori, this case was not addressed in [1]. Also, the comment misunderstands
statements made in [1] regarding the derivation of the
relativistic/nonrelativistic parts of the corrections (Eq. (47) of [1]), and
mistakenly claims they apply to the undifferenced interference signal. In this
reply we show why, because of inapplicable assumptions, approximations and
misunderstandings, the comment does not apply to the results of [1]\,.
