State-of-the-Art Airborne Gravimetry

1995
The measurement of the Earth’s gravity from aircraft has been an ongoing subject of research for over 30 years. Over the past decade, advances in technology, especially the ability to precisely position the aircraft via Kinematic GPS, have made it possible to improve the accuracy, reliability and repeatability of airborne measurements.

Systematic Error Compensation for Airborne Gravimetry

Chinese Journal of Geophysics, 2013
AbstractThe systematic error sources for airborne gravimetry are analyzed in detail using the basic mathematical model. The sources can be classified into three types: the first is the observation errors in the parking apron gravity values and the base reading of the airborne gravimeter, the second is the calibration errors of cross‐coupling correction,

Airborne absolute Gravimetry with a Quantum sensor

2023
In 2019 the French Aerospace Lab (ONERA) carried out an airborne gravity survey to test their quantum absolute gravimeter, GIRAFE, targeting three different locations in France. This was done with the support of the French Laboratory of National Meteorology (LCM-CNAM), the French Hydrographic and Oceanographic Office (SHOM), the French Laboratory of ...

Requirements for Airborne Vector Gravimetry

1992
The objective of airborne vector gravimetry is the determination of the full gravity disturbance vector along the aircraft trajectory. The paper briefly outlines the concept of this method using a combination of inertial and GPS-satellite data. The accuracy requirements for users in geodesy and solid earth geophysics, oceanography and exploration ...

Airborne Gravimetry for Geoid and GOCE

2015
DTU-Space has since 1996 carried out large area airborne surveys over both polar, tropical and temperate regions, especially for geoid determination and global geopotential models. Recently we have started flying two gravimeters (LCR and Chekan-AM) side by side for increased reliability and redundancy.

Airborne gravimetry and the Global Positioning System

IEEE Symposium on Position Location and Navigation. A Decade of Excellence in the Navigation Sciences, 2002
The capabilities of using precise range and range rate measurements to satellites of the Global Positioning System (GPS) for the determination of the platform position and its time derivatives are explored. The accuracy requirements for airborne gravimetry are reviewed, and different schemes for correcting the gravimeter measurements are presented.

Eotvos corrections for airborne gravimetry

Journal of Geophysical Research, 1968
Equations for the Eotvos correction are derived in terms of parameters for the earth's reference ellipsoid and aircraft altitude to the degree of accuracy necessary to accommodate current jet transport speeds. Distinction is made in the equations between ground speed and aircraft velocity.

COMPARISON OF ROBUST ALGORITHMS FOR AIRBORNE GRAVIMETRY

IFAC Proceedings Volumes, 2006
Abstract The problem of a gravity anomaly (GA) estimation aboard an aircraft solved by using the data from a gravimeter and phase measurements of altitude from the differential satellite navigation system is discussed. The problem is considered from the viewpoints of different robust estimation algorithms: an H ∞ estimation algorithm, a mixed H ...
