When applying the Global Navigation Satellite System (GNSS) for precise kinematic positioning in airborne and shipborne gravimetry, multiple GNSS receiving equipment is often fixed mounted on the kinematic platform carrying the gravimetry instrumentation. Thus, the distances among these GNSS antennas are known and invariant. This information can be used to improve the accuracy and reliability o...

gravity acceleration data have grand pursuit for marine applications. due to environmental effects, marine gravity observations always hold a high noise level. in this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. on the one hand, harmonic spline functions have great capability for local gravity ...

We apply the residual terrain modeling (RTM) technique for gravity forward-modeling to successfully improve high-resolution global gravity fields at short spatial scales in coastal zones. The RTM scheme is combined with the concept of rock-equivalent topography, allowing to use a single uniform constant mass-density in the RTM forward-modeling, both at land and sea. SRTM30_PLUS bathymetry is me...

The measurement of Earth’s gravitational field is important in geophysics, geodynamics, geodesy, oceanography, and space science. ocean covers 71% the earth’s surface; therefore, measuring ocean’s crucial. Compared with shipborne gravimetry, underwater gravimetry near seafloor closer to gravity sources can obtain short-wavelength information that useful for small-scale deposit detection seawate...

The precision dynamic measurement of absolute gravity based on the cold atom interferometer can provide a new method for marine gravimetry, so that it has attracted more attention. Based homemade shipborne interferometric system, we carry out series experiments in certain area South China Sea. Under conditions, suppression noise is essential improvement performance. According to physical model ...

BACKGROUND A conventional gravimetry and electro-gravimetry study has been carried out for the precise and accurate purity determination of lead (Pb) in high purity lead stick and for preparation of reference standard. Reference materials are standards containing a known amount of an analyte and provide a reference value to determine unknown concentrations or to calibrate analytical instruments...

SUMMARY In the last years scientific literature has been enriched with new models of Moho depth in Antarctica Continent derived by seismic reflection technique and refraction profiles, receiver functions surface waves, but also gravimetric observations over continent. particular, gravity satellite missions two decades have provided data this remote region Earth allowed investigation crust prope...

CO, CH4, N2O and CO2 were retrieved from high resolution solar absorption spectra obtained during a ship cruise from Capetown to Bremerhaven in January/February 2003 by Fourier Transform Infrared (FTIR) spectroscopy. Precisions of better than 0.5% for the column averaged volume mixing ratios (VMR) of CH4 and CO2 are achieved using of O2 as a reference gas. Shipborne FTIR-measurements of CO and ...

Airborne gravimetry is an important tool for the geodesy and geophysics communities. Able to provide medium to high-resolution measurements over large areas, it is the link between the low-resolution satellite measurements and expensive terrestrial campaigns, especially in remote areas. To explore the potential of airborne gravimetry, the Gravimetry using Airborne Inertial Navigation (GAIN) pro...
