Airborne Synthetic Aperture Radar: Models, Focusing and Experiments [PDF]
, 2006 Synthetic Aperture Radar (SAR) is a remote sensing technique that allows the generation of microwave images of the Earth surface, independently of weather condition and of sun illumination.

Geoid determination using airborne gravity vectors
Earth, Planets and SpaceIn traditional airborne gravimetry, the vertical component of the gravity vector is used as an approximation of the measured magnitude of the gravity vector, which enters the determination of the local geoid.

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

Airborne gravimetry for geoid determination with Lacoste Romberg and Chekan gravimeters [PDF]
, 2015 Airborne gravimetry for geodetic purposes such as geoid determination and global geopotential models requires good bias stability, as well as good performance in turbulence for large-scale national projects.

Geoid profiles in the Baltic sea determined using GPS and sea level surface
Geodesy and Cartography, 2012 The idea was to compare the geoid in sea areas by an independent method, like GPS levelling, on the mainland. On the earth surface we can compare the gravimetric geoid with GPS levelling to get an accuracy estimation and tilt information.

Performance evaluation of multi-epoch airborne gravity surveys in Kalimantan, Indonesia
Earth, Planets and SpaceThis study evaluates the performance of two multi-epoch airborne gravity surveys acquired over Kalimantan, Indonesia, during 2009–2010 (Data A) and 2021–2022 (Data B), using the LaCoste & Romberg Air/Sea S–99 (LCR S–99) and Canadian Micro Gravity GT–2A ...

Airborne geoid determination [PDF]
, 2000 Airborne geoid mapping techniques may provide the opportunity to improve the geoid over vast areas of the Earth, such as polar areas, tropical jungles and mountainous areas, and provide an accurate "seam-less" geoid model across most coastal regions ...
