non-magnetic vehicle with measurement channels
JESSY SMART is a novel measuring device for fast three-dimensional geomagnetic mapping of hidden subsurface anomalies.
JESSY SMART localizes smallest earth magnetic field gradient inhomogenities in a depths of up to
approx. 10 meters. The sensors are mounted onto a cart which can be moved attached to a motor car or alternatively pushed along manually.
To achieve the highest detection rates the system applies the most sensitive sensors presently available, Superconducting Quantuum Interference Devices (SQUIDs).
Advantages compared to conventional geomagnetic methods
Magnetogram of backfilled Neolithic ring ditches near Weimar, Thuringia
- highest possible magnetic field resolution (sensor 7 fT/cm)
- fast mapping of measuring area (up to 7 acre and accordingly 3 ha/hour)
- very accurate position and spatial resolution of data in cm range)
- measurement in difficult ground, environment, and climate conditions possible
- nondestructive measuring and a high planning reliability
