QTSI attended the 26th SAGEEP meeting held 17-21 March 2013 in Denver, CO, presenting an aspect of its work for an ARMY customer. SAGEEP, or Symposium on the Application of Geophysics to Engineering and Environmental Problems, is an international meeting of near-surface geophysical disciplines sponsored by the Environmental and Engineering Geophysical Society. The paper delivered an update on current unexploded ordnance (UXO) work for the US ARMY Corps of Engineers, Engineering Research and Development Center (ERDC), Vicksburg, MS, office.
The UXO effort was undertaken to provide a system for range sustainment. QTSI’s hardware and software solution will detect and locate artillery range impacts from significant standoff distances, classifying each impact as either fully exploded or inert (no detonation). While the system will not assist with the cleanup of existing ranges, it will help maintain ranges once installed. Highlighted in the SAGEEP presentation was the incorporation of seismic arrays to improve signal-to-noise ratio, to provide an azimuth to the impact from each array, and to refine the determination of impact location. Three field deployments and collects were shown that included both heavy artillery (105 mm and 155 mm) and lighter mortars (60 mm and 81 mm) rounds. QTSI presented the capability to deliver impact locations of the rounds with close to 2 m accuracy.
