A comparison of filtering techniques for airborne gravimetry

, 1996
Three different filtering techniques for the estimation of the gravity disturbance are theoretically outlined and numerically tested. The first approach, finite impulse response lowpass filtering, is a frequency domain method. The two other approaches, Kalman filtering and deterministic model filtering, are model based methods. An airborne gravity data

Quantification of Airborne Concentrations of Nanoscale Dusts by Particle Gravimetry Using Ionic‐Liquid Modified Polymeric Electrospun Fibers

Macromolecular Materials and Engineering
In this work, functional polymeric filters are prepared by electrospinning using four different non‐ionic polymers or their blends together with deliberately selected additives, and then tested for quantification of the nano‐sized powders.

Unmanned Aerial Geophysical Remote Sensing: A Systematic Review

Remote Sensing
Geophysical surveys, a means of analyzing the Earth and its environments, have traditionally relied on ground-based methodologies. However, up-to-date approaches encompass remote sensing (RS) techniques, employing both spaceborne and airborne platforms ...

Latest results in strapdown airborne gravimetry using an iMAR RQH unit

, 2016
This paper summarizes the results of four recent airborne gravity campaigns, carried out between October 2013 and October 2015. For the measurements, a strapdown inertial measurement unit, type iMAR RQH 1003, was used in combination with a geodetic two ...

Airborne Strapdown Gravity Measurements for Geodesy and Geophysics [PDF]

, 2018
The determination of gravity from an airborne platform, commonly known as airborne gravimetry, has been recognised as an operational procedure since the 1990s, using springtype gravimeters mounted on a stabilised platform.

Vector corrections in scalar gravimetry [PDF]

, 2018
Advances in airborne gravimetry have made increased use of global navigation satellite systems (GNSS) to successfully model unwanted accelerations, caused by the motion of the aircraft.
