Type of experiment Dual three-axis fluxgate magnetometers and a three-axis search coil
magnetometer. Triad fluxgate sensors, which utilize a ring core geometry,
are installed at the end and middle of a 6 m deployable mast. Three search
coils are mounted approximately one-half of the way out on another
6 m boom together with search coils for the VLF wave in the PWI system.
