GroundMetrics and its sister company QUASAR Federal Systems (QFS) have developed a suite of innovative new ground electromagnetic sensing devices.  The system consists of an entirely new type of capacitive electric (E-) field sensor (eQube™), a simplified wireless 24-bit DAQ (wDAQ™) , and compact magnetic (B-) field sensors (mCoil™).  The technology is optimized over the band 0.1 Hz - 100 Hz with operation from 0.03 Hz - 3 kHz.
