Evaluation of Multi-Sensor Unexploded Ordnance (UXO) Detection System Developed by Geophysical Solutions
Abstract
The Multi-Sensor System (MSS) developed by Geophysical Solutions was tested and evaluated in March 2004 at the unexploded ordnance (UXO) test site and the UXO/countermine test stand located at the U.S. Army Engineer Research and Development Center (ERDC), Vicksburg, MS. The MSS includes two sensor systems, the Geophex GEM-3-E and Geonics EM-63, as well as the Gem Systems GSMP-40 magnetometer and the NavCom SF-2050 series rover using the Starfire differential global positioning system (GPS). The MSS was found to be heavy and extreme in its length, thus making it difficult to move the MSS along a straight line. The positioning system for the cart lacked expected accuracy. With the GPS positioned near one of the pivot points, the arc of the other sensors could be moved through without any change in the GPS recording. Also, the GPS occasionally failed to keep a lock on the differential GPS signal, thus decreasing its accuracy. With the EM-63, the system did not allow for adequate channels to be saved. The EM-63 induced a large signal in the magnetometer that had to be removed. The EM-63 and GEM-3-E both produced data with similar results as those obtained from other GEM-3's and EM-63's used by ERDC.
