GUARDRAIL Integrated Processing Facility [IPF]

GUARDRAIL ground processing is conducted in the Integrated Processing Facility (IPF), which consists of of four 40-foot SeaLand trailers, interconnected to provide an advanced ground processing center for the Guardrail mission operations. The Surveillance Information Processing Facility (AN-TSQ-105(V)), commonly referred to as the Integrated Processing Facility (IPF), is a manned, ground based, control, data processing and message center. The AN/TSQ-176 Surveillance Integrated Processing Facility, consisting of four 8'x40' electronic shelters, is part of the Guardrail/Common Sensor System-1 (GRCS-1) AN/USD-9C integrated processing facility. The vans are in to to observe, analyze and process information relayed from the Airborne Relay Facility (ARF), AN/ARW-83(V). Interoperable Data Links (IDL) provide microwave connectivity between the airborne elements and the IPF. Reporting is accomplished via Commander's Tactical Terminals (CTT). Key features include integrated COMINT and ELINT reporting, enhanced signal classification and recognition, fast Direction Finding (DF), and precision emitter location. The GRCS Integrated Processing Facility (IPF) rapid deployment capability consists of two vans minimum versus the four of earlier configurations.

The Flightline Test Set AN/ARM-163 (V) is commonly referred to as the Auxiliary Ground Equipment (AGE) Van. The AGE van is a five ton step van that has been modified to contain automated test equipment used in the preflight checks and maintenance of the Airborne Relay Faclilty (ARF).

Information is processed and reported to joint consumers via TRIXS broadcast primarily over the Joint Tactical Terminal (JTT) which is a subsystem of the GRCS Data Distribution System (DDS). A typical mission requires the aircraft to orbit to the rear and parallel to the forward line of own troops (FLOT). The IPF sends commands to and receives information from the Airborne Relay Facility (ARF) through a secure data link. The operators in the IPF process the collected information and report the intelligence to the tactical commanders and other possible joint consumers via the JTT relay on board the aircraft.

The Precision SIGINT Targeting System (PSTS) is an ACTD under the sponsorship of the Deputy Under Secretary of Defense for Advanced Technology. PSTS is a Joint Service and Defense Agency effort to develop and demonstrate a near-real-time, precision targeting, sensor-to-shooter capability using existing national and tactical SIGINT assets. The third PSTS demonstration, conducted in April 1996 was held in conjunction with an Army Interdiction Counter Fire Exercise (ICE 96-1) at Fort Stewart, Georgia. This demonstration featured processing of both national and tactical SIGINT data at a tactical processing facility, the GUARDRAIL Integrated Processing Facility (IPF) located at Hunter Army Airfield in Savannah, Georgia.

GRCS systems currently collect SCAR data as part of normal operations. This SCAR data resides in a database in the GRCS Integrated Processing Facility (IPF) and is accessed by GRCS Mission Supervisors to direct the efforts of the system COMINT and ELINT Intercept Operators. Dynamic Electronic Mapping and near real time Display (DEMAND) will consist of a laptop or workstation connected via local area network to the IPF mainframe computers. DEMAND will access the database containing the SCAR data, retrieve the appropriate data elements, and populate the DEMAND database. An icon will be generated for each intercept in the database and displayed in the appropriate location on an electronic map depicting the commander's designated AOI on the DEMAND system. Unique icons will be used for each type, class, or family of emitter represented. An analyst or operator may obtain details of each emitter through the cursor selection of any individual icon. All available data elements for the selected icon are immediately displayed on the screen. Data elements include but are not limited to: Target #, Position, Frequency, Start time of intercept, and all other collected signal parametrics. Each icon will also graphically depict which sensor platform collected its associated data. Data on the DEMAND system will be in a format compatible with the All-Source Analysis System (ASAS). The data will be available to ASAS through either a "pull" or a "push" capability.

Deployment

One GR/CS system is authorized per Aerial Exploitation Battalion (AEB) in the MI Brigade at each Corps. The second GRCS system was fielded to XVIII Corps in 1994 with a remote relay capability that allowed forward deployment of aircraft while the ground processing facility remains in CONUS.
