This standard specifies the design method principles of high-precision magnetic measurement technology, performance verification of high-precision magnetometers, field measurement and data processing requirements. This standard is applicable to the exploration of weakly magnetic targets, namely: weakly magnetic mineral resources, weakly magnetic geological bodies (delineation of small structures and geological mapping, etc.), underground pipelines or metal objects, underground engineering and ancient cultural relics inspection and detection, etc.
