Development and following commercial use of the airborne electromagnetic method based on natural fields in the audio-frequency band (AFMAG) started in late 50s of the last century. After several decades of the development downtime, limitations inherent to the method were resolved in 80s by adapting the tensor analysis, remote reference noise bias removal techniques and computation of the tippers. The achievements were implemented in the ground acquisition system, and the “tipper” measurement principles employed in the following airborne system development in early 2000s (ZTEM). The latest development, MobileMT, the third generation airborne system from AFMAG family, offered for commercial surveys, overcomes the limitations of its predecessors.
