State-of-the-Art and Future Sensor Technology for Airborne Gravimetry
1995The task of airborne gravimetry is either the determination of the vertical component of the gravity vector, i.e. scalar gravimetry, or of its three components (vector gravimetry) from an aircraft.

Unlocked Potentials in Airborne Gravimetry
Recent advancements in geodesy have highlighted the dynamic interplay between theory, science, engineering, technology, and practice-oriented services. The continuous evolution of geodetic science has led to significant progress in both traditional geodetic challenges and emerging issues, often driven by innovations in instrumentation and computationalopenaire +1 more source
VERTICAL ATTENUATION OF ANOMALIES IN AIRBORNE GRAVIMETRY
Geophysics, 1971Abstract Analysis of components of the gravity anomaly field from basic one, two, and three-dimensional masses demonstrates that all components of the same derivative order attenuate with flight elevation at the same rate for a given type of anomaly. Different types of anomalies attenuate with significantly different rates. The signal

GPS and airborne gravimetry: Recent progress and future plans
Bulletin Géodésique, 1991The logistical difficulties and expense of measuring gravity over the surface of the earth or ocean provides the motivation for developing techniques for airborne data acquisition. To meet this need, the U.S. Naval Research Laboratory (NRL) has had an active research program in airborne gravimetry since 1979.

Intermap’s Airborne Inertial Gravimetry System
2011The airborne gravimetry system provides an efficient tool to collect the homogeneous airborne gravity data over large areas. For this purpose Intermap has developed a new Airborne Inertial Gravimetry System (AIGS), based on the GPS/INS components of Intermap’s Interferometric SAR (IFSAR) system and the airborne gravity process software, called StarGrav.

A preliminary analysis of the NRL airborne gravimetry system
Geophysics, 1984Abstract The Naval Research Laboratory has developed an airborne gravimetry system for marine use. The system utilizes global positioning system navigation and high-resolution radar altimetry to overcome the major difficulties of Eotvos correction and vertical acceleration determination. Precise measurements of aircraft motions permit

FVM: A Good Match to Airborne Gravimetry?
Numerical methods like the Finite Element Methods (FEM) or Finite Element Methods (FVM) are widely used in many engineering applications to solve boundary value problems that are hard to find rigorous analytical solutions. These numerical methods have been also applied in geodesy in many previous studies regardless of its huge computation demands. TheyXiaopeng Li +8 more

Determination of Moving‐Base Acceleration for Airborne Gravimetry
Chinese Journal of Geophysics, 2003AbstractAirborne gravimetry is a new technique for determination of earth gravity, in which gravimeter, GPS and other sensors are used. Its basic theory is that gravimeter senses the total accelerations including gravity acceleration, inertial acceleration and some other accelerations; and GPS determines inertial acceleration of moving‐base; then ...
