Since calibration parameters determined for the G-65 gravimeter
(Oja et al.
It was based on the determinations of absolute gravity values with a JILAg-5 gravimeter
in 1995 as well as relative gravity connections with LCR (LaCoste&Romberg) G-type spring gravimeters
As a result of this design change, the commercially manufactured absolute gravimeter
now satisfied Abbe's dictum: If you want to measure something in a particular direction, then build the apparatus along that direction and avoid measuring in orthogonal directions, which will likely introduce cross-couplings such as--in the case of the "side-by-side" JILAg gravimeter
--a tilt sensitivity.
Gravity acceleration, g, is determined by a commercial gravimeter
, which records the trajectory of a corner cube dropped in a vacuum.
After searching the South Pole data, Nawa found weak but continuous oscillations, about a trillionth of the strength of gravity at Earth's surface, picked up by the gravimeter
Our model and theory of gravity  is based on a flux of particles, and the "narrow beam" is interpreted due to very low-angle elastic scattering of external particles by the nucleons of the celestial bodies [11,12], particularly the Moon (near body in ) and Sun (far body), such that some particles never reach the detecting apparatus such as pendula, gravimeter
, or radioactive source-detector system.
Ian Lumb, both at York University in Toronto, think these fluctuations in the gravity field were caused by "inertial waves,' or oscillations of the outer-core fluids, which redistributed the mass in the core and hence changed the reading on the Belgium gravimeter

With the introduction of a new portable absolute gravimeter
, Micro-g will complement Scintrex's existing line of gravimeters
and its well established sales and marketing channels to significantly increase its market share in the years to come.

This results in changes in zero position, known also as gravimeter
The Division's CG-3 AutoGrav Gravimeter
, the ENVI Geophysical Systems, the IPR-12 Induced Polarization receiver, the SMARTMAG and CS-2 high-resolution magnetometers remain top sellers and the leading products in their category.
