GS 800 - Introduction to Airborne Gravity

Package: GS 800 – Introduction to Airborne Gravity

Course Module: GS 201 – Airborne Gravity Quality Control

2022-05-12T01:29:12-05:00

Learning Objectives: After completing this module, participants will understand quality control techniques that can be used for monitoring airborne gravity data, such as: Drift Monitoring using Static Testing, Repeatability using Test Lines, Intersection Statistics, Leveling Corrections, Line Deviations, Horizontal And Vertical Accelerations due to Aircraft Motion, Oversampled Grids, and more.

Course Module: GS 102 – Standard Gravity Corrections Applied to Airborne Gravity

2022-05-12T01:32:13-05:00

There are several standard corrections that are applied to any gravity data set. The module starts with  a summary on what is a gravity system and a description of the two main types: absolute and relative. We review how gravity can measure density and/or structural variations. That leads you the main objective of the module which is to discuss the different standard gravity corrections that are applied to all gravity data sets: the theoretical ellipsoidal gravity (latitude correction), atmospheric effect, height (Free Air) correction, and terrain effects (Bouguer correction).

Course Module: GS 101 – Airborne Gravity Systems and Survey Design

2022-05-12T01:33:13-05:00

This module addresses what is an airborne gravity system. The module starts with a reference to gravity variation and acceleration. It takes you through the different types of gravity systems. Simply, there are two types of highly sensitive accelerometers used to measure the earth’s gravity field. The instruments and the calibration required are discussed.
