1998) reported modal peaks of seismic hum recorded by a superconducting gravimeter
at Syowa Station, Antarctica.
Comparing the results obtained using the ZZG and FG-5 gravimeters
it can be concluded that the maximum discrepancies between the determinations reach up to 20[micro]Gal.
Calibration results of different type spring gravimeters
from the repeated measurements of Estonian calibration lines.
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
The first of these quantities is now days a solved problem since the gravimeters
are capable to offer high accuracy in gravity differences.
Figure 11 shows the first of the laser interferometric absolute gravimeters
, which was developed as part of the Ph.
Observations of gravitational acceleration with La Coste & Romberg (G model) and Scintrex CG-3M Autograv gravimeters
have been carried out since 1992 (Barlik, Cacon, 2001).
The survey was accomplished with four spring gravimeters
, three LaCoste & Romberg and a digital Scintrex gravimeter
Indeed, some laboratory devices, such as interferometers and gravimeters
, have already begun to incorporate the new technology (SN: 8/8/98, p.
have been used in the air with some success in defining features with a scale of 10 km or greater, but the next generation of airborne gravity instruments will be gradiometers targeting features 200 to 500 m beneath the ground surface with density contrasts about 300 kg/m3 and smaller than 1 km across.
Flights administered by Naval Research Laboratory Scientific Development Squadron One (VXS-1) were flown using NP-3D Orion turboprop aircraft specially equipped with a suite of unique state of the art remote sensing technology that included dual gravimeters
, scalar and vector magnetometers, a digital photogrammetric camera, hyperspectral imager and an L-band polarimetric synthetic aperture radar.
Land gravimetric measurements on Polish territory were made over the period 1957-1979 using Askania, Sharpe, Scintrex, Sodin and Worden gravimeters
The payload is related to hydrography and oceanography and consists primarily of - Various pollsters,- Gravimeters
,- Current meters,- Inertial units,- An implementation of the core barrel,- A salinometer- A velocimeter.
3 and invar rods with bar code scales Wild GPCL3, Zeiss LD13, Zeiss LD11 and gravimeters
Scintrex CG-3 and CG-5 were used for measurements.
The FG5 is a new generation of absolute ballistic gravimeters
based on a technology developed for forty years by Dr.
