VIDL Network introduces you to advances in instrumentation and navigation technology which have brought airborne gravimetry, the measurement of Earth’s gravitational field strength using instruments aboard aircraft, to an unprecedented 1–2 milligal level of accuracy today. This means that scientists can now use aircraft to map tiny gravity changes that are 1 million times smaller than 1 g0 (standard gravity), allowing them to make detailed maps of buried resources and enabling high-precision geodetic applications.
