AN/TSQ-134(V) Advanced Electronic Processing and Dissemination System (AEPDS)

The Army's Advanced Electronic Processing and Dissemination System (AEPDS) is a C-130 transportable system that supports Corps and Echelon Above Corps (EAC) commanders by receiving and processing intelligence data collected by national, theater and corps sensors. The AEPDS supports close, deep, rear, and special operations by providing the ability to see deep into the battle area and by providing targeting, terrain, and ingress/egress information. The AEPDS maintains the tactical commander's SIGINT data base and serves as a pre-processor for the MITT, FAST, GSM, DTSS and ASAS. Sensor data is correlated and integrated, then forwarded to other tactical commands supported by Tactical Exploitation of National Capabilities (TENCAP) system within consumer timeliness requirements. The data is correlated and integrated, then forwarded to other tactical commands supported by Tactical Exploitation of National Capabilities (TENCAP) system in required timeliness. The AEPDS interfaces with current Intelligence and Electronic Warfare (IEW) processing and dissemination systems, including the All Source Analysis System (ASAS) Block II upgrade which will allow interface with AEPDS.

The AEPDS combines the functions of the EPDS and the ETUT in a single downsized self contained system.

With the fielding of the Advanced Electronic Processing and Dissemination System (AEPDS) in 1997, the older EPDS system became obsolete and is in the process of being taken out of the field. The systems operated by both Air Force and Army units are located at ten installations around the world. In addition to the systems in the hands of users, the ASPO has a significant stockage of repair parts, a training facility at Ft Huachuca, AZ., and an operational laboratory system. Prior to the defielding, ASPO determined that many of the components inside the EPDS system could still satisfy requirements within the Army and Air Force. All the potential claimants for the materiel were notified and requested to help in the defielding effort. The current claimants to date are: The USAF Space and Missile Center (Data Acquisition System (DAS) equipment), two national special access programs (DAS equipment), US Army Guardrail System (All workstations), Naval Research Laboratory (empty van) and ASPO (all communications equipment and vans). At the conclusion of the defielding, there will be almost nothing left.

A miniaturized data acquisition subsystem (MINI-DAS or MIDAS) integrated into the existing UNIX-Based ETUT-Rs. Along with this S-Band capability, the software functionality of the EPDS will also be intergrated into the software of the ETUT-R. The result is a single system known as the AEPDS that will fit inot the footprint of the current ETUT-R. Once a site has their ETUT-R upgraded into a AEPDS, their EPDS will be defielded.

The AEPDS consists of four UNIX-based SUNSPARC which are interchangeable and two file servers. One file server is used for the system the other as a back-up and external LAN that enables other TENCAP and IEW systems to read the AEPDS data base. It also has Communications System Processor (CSP), SUCCESS Ultra-High Frequency (UHF) radio, image and text printers, land-line modems, KY-68 telephone, STU-III and other cryptographic equipment. AEPDS interfaces with all other TENCAP systems, Hawkeye/Warrior, AUTODIN, Tactical Receiver Equipment (TRE) and Related Application Program (TRAP) and all other TADIXS-B broadcasts, Mobile Subscriber Equipment (MSE), public switched and leased line telephone networks, Trojan Spirit and all National Imagery Transmission Fromat (NITF) complaint Secondary Imagery Dissemination (SID) producers and consumers.

Deployed Units

The initial AEPDS fielding was in 1997. All four corps and the EAC MI brigades received the system.
