WalkTEM

WalkTEM is a transient electromagnetic (TEM) instrument and the result of in-house development over the past decades. In principle the WalkTEM is a SkyTEM instrument with a less powerful transmitter, though the standard transmitter has a maximum output current of 20 A , superior to common groundbased TEM systems. Recently new powerful transmitters have (TEMtX60) been developed with a maximum output current of 60 A, especially designed for very deep surveying. The WalkTEM instrument has a built-in GPS, ensuring precise positioning and elevation data for each measurement.The instrument is commercially sold by ABEM.

The HGG group has extensive experience with the development of processing and interpretation software for groundbased TEM-system, where ViewTEM/SPIA is the newest  development from our software group.
