AIRCRAFT EQUIPPED FOR AIRPORNE VECTOR MAGNETIC EXPLORATION SURVEYS AND METHOD OF PROECESSING DATA COLLECTED DURING AIRBORNE SURVEY

摘要

The present invention relates to an aircraft equipped for airborne vector magnetic exploration surveys, comprising : a gravity gradiometer having an inertial navigation system comprising two rotation sensors mounted to measure the angular orientation of the aircraft; three magnetometers orthogonally mounted to measure the components of the earth's vector magnetic field ; and a recording system to record the measurements of the magnetometers and rotation sensors ; where, the measured angular orientation is used to orientate the measured components of the earth's vector magnetic field, to derive true vector magnetic data from airborne surveys, that is vector aero-magnetic (VAM) data. A method of processing data collected during an airborne survey is also disclosed
