A pilot Personal Identification Credential System (PICS) has been developed and fielded. The PICS is a wireless biometric credential that interfaces with access control systems. The PICS consists of individual handheld Personal Identification Credentials (PIC), a PICS Reader located at a facility entry control point that interfaces with the facility entry control system, and a PICS Enrollment Station. In operation, an individual approaching a facility entry point in a vehicle picks up the PIC handheld unit and places a finger on its sensor. The PIC then authenticates the user and from within the vehicle initiates two-way, secure RF communication with the PICS Reader as the vehicle approaches the gate. The PICS Reader then verifies that the individual is authorized for admittance and notifies the facility gate entry control system, which informs the sentry that the request for access was successful or unsuccessful. If the request for access is unsuccessful, the gate entry control system automatically will close the gate. This sequence of events takes place while the car is moving through a normally open entry lane.
The PIC is a small, handheld device which contains the biometric sensor (fingerprint sensor), wireless RF transceiver, processor, encryption and battery. The PIC may be used while traveling in a vehicle or may be used while on foot for access to a PICS controlled man gate or secure area access portal. The PIC is small enough to be carried in a shirt pocket, or it can be left in the user's vehicle. The PIC battery will power the PIC for months and is rechargeable. Up to 10 fingers may be stored in the PIC.
Under contact to the United States Army, EG&G Technical Services currently is conducting field tests of the Ground Standoff Mine Detection System (GSTAMIDS) Block 0 Engineering, Manufacturing and Development (EMD) systems. GSTAMIDS is a spiral development effort designed to provide the war fighter an incremental, near-term capability to execute on-road countermine missions. GSTAMIDS is being developed in three distinct blocks. The primary mission for GSTAMIDS Block 0 is route clearance, automatically detecting and marking all metallic and non-metallic Anti-Tank (AT) mines. It consists of a Mine Detection and marking System (MDS) mounted on a teleoperated Mine Detection Vehicle (MDV) and a Main Computer System (MCS) mounted in a Mine Protected Clearance Vehicle (MPCV). Both vehicles have overpass capability for AT mines, as well as armor anti-mine blast protection. The MPCV mounted MCS receives sensor data, along with inertial navigation data, from the MDS via an RF PCM telemetry link, automatically processes and fuses the data for mine detection and sends mine marking commands back to the MDV. The MDS sensors provide a three-meter detection swath and include nine (9) Ground Penetrating Radars (GPR), nine (9) Pulsed Magnetic Induction (PMI) metal detectors, and (as an option) two (2) long-wave infrared (LWIR) cameras. Contractor testing includes raw sensor data collection and sensor evaluation, performance (Pd and FAR), operating and storage environment, and EMI/EMC radiated emissions and susceptibility, as well as maintenance demonstrations. Testing has been conducted at a number of test mine lanes in different climates under a wide range of weather conditions over the past year and a half. This paper will present contractor test results to date.
The United States Army has contracted EG&G Technical Services to build the GSTAMIDS EMD Block 0. This system autonomously detects and marks buried anti-tank land mines from an unmanned vehicle. It consists of a remotely operated host vehicle, standard teleoperation system (STS) control, mine detection system (MDS) and a control vehicle. Two complete systems are being fabricated, along with a third MDS. The host vehicle for Block 0 is the South African Meerkat that has overpass capability for anti-tank mines, as well as armor anti-mine blast protection and ballistic protection. It is operated via the STS radio link from within the control vehicle. The Main Computer System (MCS), located in the control vehicle, receives sensor data from the MDS via a high speed radio link, processes and fuses the data to make a decision of a mine detection, and sends the information back to the host vehicle for a mark to be placed on the mine location. The MCS also has the capability to interface into the FBCB2 system via SINGARS radio. The GSTAMIDS operator station and the control vehicle communications system also connect to the MCS. The MDS sensors are mounted on the host vehicle and include Ground Penetrating Radar (GPR), Pulsed Magnetic Induction (PMI) metal detector, and (as an option) long-wave infrared (LWIR). A distributed processing architecture is used so that pre-processing is performed on data at the sensor level before transmission to the MCS, minimizing required throughput. Nine (9) channels each of GPR and PMI are mounted underneath the meerkat to provide a three-meter detection swath. Two IR cameras are mounted on the upper sides of the Meerkat, providing a field of view of the required swath with overlap underneath the vehicle. Also included on the host vehicle are an Internal Navigation System (INS), Global Positioning System (GPS), and radio communications for remote control and data transmission. The GSTAMIDS Block 0 is designed as a modular, expandable system with sufficient bandwidth and processing capability for incorporation of additional sensor systems in future Blocks. It is also designed to operate in adverse weather conditions and to be transportable around the world.
