Absolute and Relative Gravimetry
Absolute and relative gravimetry allow the determination of gravity acceleration, usually just called gravity, for specific positions as well as the detection of gravity changes with time at a givenExpand

High tilt susceptibility of the Scintrex CG-5 relative gravimeters
We report on the susceptibility of the Scintrex CG-5 relative gravimeters to tilting, that is the tendency of the instrument of providing incorrect readings after being tilted (even by small angles)Expand

Precise definition of the effective measurement height of free-fall absolute gravimeters
For up-to-date absolute gravimeters, the trajectory of the test mass during a free-fall experiment (drop) is about 20 cm along the vertical, and the corresponding gravity change is about 60 × 10 −8Expand

Precision Gravimetry in the New Zugspitze Gravity Meter Calibration System
The precise calibration of relative gravity meters is essential for the accuracy of gravimetric surveys. We show that in the new Zugspitze cali- bration system established in 2004 - 2005 excellentExpand

Atmospheric Mass Flow Reduction for Terrestrial Absolute Gravimetry in the Fennoscandian Land Uplift Network
Temporal variations of the atmospheric density distribution induce changes in the gravitational air mass attraction at a specific observation site. Additionally, the load of the atmospheric massesExpand

Geodesy and metrology with a transportable optical clock
An atomic clock has been deployed on a field measurement campaign to determine the height of a mountain location 1,000 m above sea level, returning a value that is in good agreement with state-of-the-art geodesy. Expand
