A remote characterization system (RCS) will be used at Aberdeen Proving Ground (APG) Edgewood Area to execute geophysical surveys on {approximately}200 acres at Carroll Island and up to 50 acres at Graces Quarters to verify the boundaries of potential burial or disposal sites identified during previous investigations or site walkovers. RCS development was a coordinated effort between Pacific Northwest Laboratories, Oak Ridge National Laboratory, Idaho National Engineering Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories. The remotely piloted vehicle can be equipped with numerous sensors including magnetometers, electromagnetic-induction sensors, ground-penetrating radar (GPR), gamma radiation detectors, and photoionization detectors. The vehicle is designed with a minimum of ferrous metal to present a low electromagnetic signature to each of the sensors, thereby limiting interference with sensor operation. A base station houses the controls and monitors. Control commands sent from the base station and data from two video cameras mounted on the front and back of the RCS are used to drive the vehicle. Commands are transmitted via an ethernet link on a microwave frequency. Sensor readings flow continuous from the RCS to the base station. A differential global positioning system (GPS) is used to track the position of the vehicle, in real time, with an accuracy of less than a meter. GPS data can be further processed to achieve centimeter accuracy.
