VIDL Network introduces students to the application of airborne gravity. It starts with the advances in instrumentation and navigation technology that have brought airborne gravity to a cost effective data acquisition method. The measurement of the Earth’s gravitational field strength using instruments aboard an aircraft today have reached an unprecedented 1-2 milligal level of accuracy. This means a scientist can use an aircraft to acquire viable data to map small gravity field changes that are 1 million times smaller than the 1 g° (standard gravity value). This capability allows them to make detail maps of buried resources and enabling high-precision geodetic applications.

Airborne Gravity was developed primarily for petroleum exploration, where it is an economical alternative to ground and shipborne surveys.  It also has exciting application in regional geophysics, mineral exploration and geodesy. The learning objective is taking you through an introduction of the science starting with types of instrumentation to survey design, data processing and data quality control.
