Two Zener Diode detectors were oriented in inertial space so that the flow passing first through one detector and subsequently the second detector would produce correlated current output.
Cahill which reported an effect that is consistent with the absolute motion of the earth through inertial space.
It is the ideal inertial coordinate frame; at the starting time for the initial alignment, i frame coincides with e frame and is fixed in the inertial space.
b0] frame coincides with b frame and is fixed in the inertial space.
The stable member is held fixed in inertial space
at an attitude initialized by the fire control system during a pre-launch sequence.
The freely falling mirror was isolated by being in inertial space
; the long-period isolator served to also locate the reference mirror in inertial space
