OPERATIONAL REQUIREMENTS DOCUMENT (ORD)
TECHNICAL CONTROL AND ANALYSIS CENTER (TCAC)
PRODUCT IMPROVEMENT PROGRAM (PIP)
(NO. INT 1.31)
1. General Description of Operational Capability
a. The Technical Control and Analysis Center (TCAC) will become the focal point of Radio Battalion Signals Intelligence (SIGINT) operations within the Operations Control and Analysis Center (OCAC) and a key segment of the Marine Air-Ground Intelligence System (MAGIS). The TCAC was originally fielded in the late 1980s as the AN/TSQ-130 to provide automated assistance for the processing, analysis and reporting functions of the Fleet Marine Force Radio Battalion in order to fulfill its mission of providing timely, accurate SIGINT/Electronic Warfare (EW) support to Marine Air-Ground Task Force (MAGTF) combat operations. This system must be capable of directing and managing the technical and operational functions of other Radio Battalion SIGINT/EW assets and of providing communications connectivity for data exchange with these systems as well as the Intelligence Analysis System (IAS).
b. TCAC PIP is applicable to Mission Area 12 (Intelligence) and addresses Capabilities 3, 6, 11, 17, 38, and 43 of the MAGTF Master Plan (MMP) of 28 June 1991.
c. This requirement was originally described as the Stand Alone Analysis Subsystem of the Required Operational Capability No. INT 1.25 for an Integrated Signals Intelligence System (ISIS), dated 16 March 1983. Minor hardware and software modifications/upgrades to the AN/TSQ-130 have not prepared the system to adequately satisfy present operational requirements.
A more dynamic and capable system is needed to provide the Radio Battalions the capability to manage the numerous collection systems available to it.
d. System Description. Each system will consist of three Remoteable Analysis Work Station (RAWS), one Communications Interface Module (CIM), and one Supervisor Control Module (SCM). Each workstation will consist of modularly designed component equipments fully integrated to perform their intended functions. Each TCAC will consist of:
(1) Remoteable Analysis Work Station (RAWS). A RAWS will provide the capability to perform necessary analysis and reporting functions at a central location or a more forward deployed site, remoted from the TCAC shelter. During shelter operations, a RAWS will be electrically interconnected to the other terminals in the shelter. During remote operations, a RAWS will be connected to the shelter via local area network or a radio link. It also could operate in a stand-alone mode.
(2) Communications Interface Module (CIM). The CIM will provide man-machine interface to communication sub-routines which support the interface between the TCAC PIP and other Radio Battalion systems (i.e. - Team Portable Communications Intelligence System (TPCS), Mobile Electronic Warfare Support System (MEWSS) etc.) or external intelligence agencies.
(3) Supervisor Control Module (SCM). The SCM will provide a man-machine interface to fileserver and supervisor sub-routines to support system control and overall supervision of the TCAC PIP workstations.
e. Pre-Planned Product Improvements. The TCAC system will undergo a series of hardware and software enhancements during the product improvement. The development approach will maximize use of non-developmental item (NDI)/commercial off-the-shelf (COTS) to enhance capabilities and keep pace with the fielding of other SIGINT systems. If functional requirements are not technologically feasible at the time of the initial PIP effort, future improvements to the system will be pursued as technological advancements become feasible.
a. The Marine Corps Campaign Plan, the Marine Corps Long-Range Plan and the MMP discuss present and projected threats confronting United States forces in the execution of combat operations. The worldwide EW threat to TCAC remote operations using a radio link is documented in various Defense Intelligence Agency classified technical publications and regional EW capabilities studies.
b. TCAC operators and equipment will be vulnerable to standoff weapons such as rockets and artillery, air delivered ordnance (conventional and unconventional), etc., and
possibly direct action from unconventional units. Intercept and jamming of reporting frequencies should be anticipated.
3. Shortcomings of Existing Systems
a. Shortcomings of the current TCAC system include:
(1) Outdated data processing hardware with inadequate processing capability and increasing repair problems.
(2) No capability to receive direct data input from Radio Battalion collections systems.
(3) Size and weight which does not promote rapid or effective employment.
(4) No software applications to aid analysis.
(5) Lack of map graphic display and analysis aids.
b. Current TCAC capabilities do not support the needs of the Operations Control and Analysis Center for automated information processing. Many processes are performed manually, such as data base entry which causes unacceptable time delays in satisfying mission requirements. As more automated and semi-automated SIGINT collection assets are fielded, it will be increasingly difficult for the current TCAC to perform its mission. The planned fielding of systems such as the TPCS and MEWSS, dictates that TCAC PIP have comparable state-of-the-art hardware and software. Improvements must address both data manipulation capabilities and communications connectivity.
4. Capabilities Required. State of the art Automated Data Processing equipment to increase processing capability while decreasing system size and weight is required. TCAC PIP will require a more dynamic and capable communications interface (to include secure high frequency (HF), Very High Frequency (VHF), Ultra High Frequency (UHF) or Satelite Communications (SATCOMM) data/voice connectivity) in order to exchange data and communicate. Stand alone workstations must allow increased employment possibilities with small detachments and allow dispersal of assets in decentralized operations support.
a. System Performance. Each system will consist of at least three RAWS, one CIM and SCM. Each operator terminal/position, regardless of primary configuration, will be capable of reconfiguration to function as a remote terminal, supervisor terminal or analysis terminal. The RAWSs will be capable of in-shelter as well as remote operations. RAWSs, when operating remotely from the TCAC shelter, will be electronically tethered to the shelter by either a local area network or an HF, VHF, UHF, or SATCOMM radio link. Either link must provide secure communications connectivity.
(1) The system must:
(a) Receive, process and report on SIGINT and ELINT information gathered by organic collection elements.
(b) Provide the supported tactical commander with SIGINT and EW information on a near-real-time basis.
(c) Provide intra-system communications (opscomm and data transfer) between supervisory/management personnel and analyst/operators.
(d) Provide for communications interface between present and future Radio Battalion systems, i.e., the TPCS, the ESS, the AMASS, and present and future Radio Reconnaissance voice and data equipment (i.e.- the Joint Advanced Special Operations Radio System (JASORS)).
(e) Be mobile, rugged, and transportable using tactical and strategic aircraft and amphibious shipping.
(f) Provide automatic routing of incoming messages to work station users based on user set profiles. TCAC hardware and software must support the exchange of SIGINT data with other systems, as required.
(g) Facilitate traffic analysis functions by providing:
1 Semi-automated, initial processing of formatted reports, to include Joint Interoperabity of National and Tactical Command and Control Systems (JINTACCS) and locally generated reports.
2 The ability to produce, manage, and display files, records, and data.
3 The capability to produce preformated message masks to assist in timely reporting.
4 The capability to produce hardcopy printouts.
(h) Facilitate routine cryptanalytic functions, including the capability to:
1 Perform basic cryptanalysis and display results of cryptanalytic decisions to the user.
2 Display, chart and print results.
3 Store, forward, maintain, and manipulate cryptanalytic messages.
4 Perform routine cryptanalytic functions.
(i) Facilitate collection management functions by providing routines to perform statistical analysis and to store/maintain the Intercept Tasking Data Base.
(j) Include the necessary means for physically destroying/disabling selected cryptographic equipment items, and for purging the data base (five minute maximum time limit).
(k) Perform the following analysis functions:
1 Display, print, and plot graphics.
2 Perform, predict, and display direction finding plots, Line of Bearing correlations, communications frequency usage.
3 Store, forward, maintain, and manipulate Technical Extracts for Traffic Analysis (TEXTA).
(l) Provide required connectivity with Tactical Receive Equipment (TRE) and desired connectivity with the Commander's Tactical Terminal, if fielded.
(m) Provide required interface capability with ether net standard local area network (LAN) devices.
(2) During garrison operations the TCAC PIP will operate approximately eight hours a day, five days a week. Functions will include database maintenance, contingency planning and operator proficiency training. During wartime operations the TCAC will operate 24 hours a day, seven days a week. Functions will include traffic analysis, information reporting, database maintenance, mission tasking, and collection management support.
(3) The TCAC PIP must operate in a shelter with outside ambient air temperatures as high as +52 Celsius and outside maximum solar radiation (360 BTU/FT2/hr). The TCAC PIP must operate in a shelter with outside ambient air temperatures as low as -30 Celsius. After a period of non-operation, transportation, or storage, the system will have a 30 minute warm-up period, after which the system shall meet full performance specifications.
(4) The RAWS, when operating independently of the shelter, must operate with outside air temperatures between +52 Celsius and 0 Celsius.
b. Logistics and Readiness
(1) The logistic philosophy for TCAC PIP will be based on the following:
(a) Equipment selected for integration will emphasize maximum use of non-developmental items (NDI), commercial off-the-shelf (COTS) and government furnished equipment (GFE).
(b) Existing logistics programs providing support for GFE will be used for system support whenever possible.
(c) When contractor furnished equipment is required, existing off-the-shelf equipments will be used when possible. Maintenance and operator manuals applicable to off-the-shelf equipments and written to "best commercial practice" will be scrutinized for their applicability and thoroughness. Commercial manuals will be supplemented as required to ensure acceptability. Custom designed equipment, special purpose test equipment, and special support equipment will be discouraged.
(d) New software developed for the TCAC PIP will be developed in accordance with DOD-STD 2167A. Post deployment software support will be provided for the service life of the system. Off-the-shelf software documentation will be scrutinized for applicability and thoroughness. All source code will be documented and commented throughout.
(e) Modularity will be emphasized in the selection of all basic equipment and software.
(f) Built-in-test (BIT), without the use of separate test equipment, will be developed for system check-out and fault isolation to the lowest replaceable unit (LRU) level (printed circuit board level desired). Initial Issue Provisioning (IIP) of maintenance items will establish maintenance support.
(2) The specified interval for the TCAC system is a Mission Duration (MD) equal to 24 hours of continuous operation. An operational mission failure is defined as that condition in which the system cannot perform any essential mission functions. The TCAC system will have a minimum acceptable Mean Time Between Operational Mission Failure (MTBOMF) of at least 50 hours more than the smallest MTBOMF of any GFE and a desired MTBOMF of 300 hours.
(3) The logistic philosophy for TCAC PIP will be based on the following:
(a) The Mean Time To Repair (MTTR) shall be no more than one hour for unscheduled maintenance at the organizational level. Intermediate level unscheduled maintenance MTTR desired goal will be two hours.
(b) The desired Maximum Time to Repair (MaxTTR) at the 90 percentile for OLM is one hour; and the MaxTTR at the 90 percentile at the Intermediate Logistics Maintenance (ILM) is two hours.
(c) The required Maintenance Ratio (MR) for the TCAC PIP will be developed as the system becomes defined.
(d) The TCAC PIP is a critical low density (CLD) Marine Automated Readiness Evaluation System (MARES) reportable item.
(4) The desired operational availability (Ao) of this system is 90% within a 48 hour period. The desired achieved availability (Aa) of this system is 90% within a 48 hour period.
c. Critical System Characteristics
(1) The TCAC must be capable of operations in all climatic conditions and geographic locations in which a MAGTF can be expected to operate, and during times of limited visibility (rain, smoke, fog, darkness). Additionally, the system must be operable by personnel wearing nuclear, biological, and chemical or cold weather clothing.
(2) The system must be human engineered to allow for efficiency and safety of operations.
(3) System set-up/tear-down will be based on all tasks required to prepare the TCAC for operations, to prepare the system for relocation, or to terminate operations. The physical and technical characteristics of the system will be required to keep the set-up and tear-down times of the system to a minimum. The maximum time allowed for total system set-up will be thirty minutes. System set-up time will include provisioning of power, environmental control, manual patching, equipment turn-on, and testing of system interfaces. From its operating condition, the system must be prepared for shipping/travel within thirty minutes. System tear-down time includes disassembly, storage, packing, and protecting critical system elements.
(4) Each RAWS must be powered by 24/28 volts, direct currrent (VDC) vehicle sources or 115/220 volts, alternating current (VAC), 50/60 hertz (Hz) standard Marine Corps electric power generators and/or commercial power and have electrical interface protection from power fluctuation. The RAWS must be capable of operation in a shelter (as a CIM or SCM), stand alone operations and independent operation within a high mobility, multi-wheeled vehicle (HMMWV).
(5) The CIM and SCM must be installed in High Mobility Multipurpose Wheeled Vehicle mounted shelters with self-contained power source with an environmental control unit for in shelter operations.
(6) The system will withstand the environmental effects imposed by routine methods of military and commercial transportation.
(7) The system will include all equipment necessary for total operation.
(8) The system will meet the standards of the National Policy on Control of Compromising Emanations.
(9) Nuclear hardening is not applicable, but the equipment must survive flash effects of nuclear explosions to the same extent as operators with nuclear, biological, chemical (NBC) protective clothing. Maximum protection feasible against electromagnetic pulse radiation must be provided for electronic components and storage devices. Current integrity for electromagnetic interference, grounding and bonding, and electrostatic discharge will be maintained.

5. Integrated Logistics Support (ILS)
a. Maintenance Planning
(1) DoD commonality for the TCAC PIP will be pursued to reduce publications, spares and training cost. An appropriately tailored MIL-STD-1388A Logistic Support Analysis (LSA) will be initiated and performed in conjunction with system integration. Usage of previously conducted logistics support planning documentation will be used, if available, for NDI systems. If not available, funding will be identified within the program for logistics planning and analysis.
(2) The level of maintenance and repair will be based on an approved Level of Repair Analysis (LORA) in conjunction with LSA results. The level of maintenance and repair will be based on LSA results. Maintenance tasks include troubleshooting, preventative maintenance, repair/replacement of defective replaceable assemblies, and system replaceable assemblies. The results of the LSA will be used to determine the approach for contractor versus organic government repair.
b. Support Equipment. It is desired that Built in Testing (BIT), without the use of separate test equipment will meet the following parameters:
(1) Detect .90 of all specified faults or failures.
(2) The percentage of false alarms will not exceed .10 of total alarms.
(3) Fault isolation of the valid alarms will correctly identify .90 to the LRU level involved, and .90 down to specific boards in each CPU.
(4) To the maximum extent possible, general purpose test equipment (GPTE) and common tools resident in Marine inventory will be used to perform all corrective and preventive maintenance at all authorized levels of maintenance.
(5) Any tools and test equipment required not resident in Marine Corps inventory will be identified as special tools and special purpose equipment (SPTE), respectively.
c. Human Systems Integration. It is desired that personnel requirements to operate and maintain the TCAC PIP will not be impacted by this product improvement. The current and future density of Radio Battalion analysts will complement the manning of this system. Training requirements for the TCAC PIP will be supported within the current training system with minimal additional training provided to supervisors and managers of the TCAC system. Training for maintenance personnel will be accomplished within existing manpower constraints.
d. Computer Resources. TCAC PIP must maintain an open architecture by making maximum use of NDI/COTS hardware and software. TCAC is a systems integration system and must be flexibly designed to operate on current and future architectures and incorporate current and future sensors provided by multiple sources.
e. Other Logistics Considerations. The TCAC PIP will not require any unique handling, packaging, facility, or transportation considerations.
6. Infrastructure Support and Interoperability
a. Command, Control, Communications, and Intelligence. The TCAC PIP design must consider the effects of enemy electronic countermeasures operations and incorporate effective electronic counter-countermeasures design. It is desired that the TCAC PIP will provide protection from electro-optic and multi-spectral sensor recognition. The TCAC PIP must be capable of interface with the following systems (as indicated):
(1) Team Portable Communications Intelligence System.
(2) Joint Advanced Special Operations Radio System.
(3) Tactical Electronic Reconnaissance Processing and Evaluation System (via record Defense Special Security Communications System (DSSCS) communications paths).
(4) Tactical Receive Equipment (TRE) with physical incorporation of TRE into shelter desired.
(5) Theater/Naval airborne SIGINT systems.
(6) AN/MLQ-36 Mobile Electronic Warfare Support System.
(7) AN/MSC-63A Communications Central.
(8) Intelligence Analysis System (IAS).
(9) Defense Special Security Communications System via Automated Defense Intelligence Network (AUTODIN) Switching Center (desired).
(10) Comint Collection Outstation (desired/if fielded).
(11) Commander's Tactical Terminal (CTT) (desired).
b. Transportation and Basing. TCAC PIP will be capable of external air transport via CH-53 or internal air transport via C-130 or larger aircraft. The system will be ground transportable by a logistics vehicle system, HMMWV desired. The TCAC PIP will require a dedicated vehicle to support power requirements. When in garrison, the TCAC PIP will be dismounted from the vehicle and located in the Radio Battalion's OCAC area for use in garrison. During deployment, the TCAC PIP will be located with the OCAC section of the Radio Battalions or smaller detachments.
c. Standardization, Interoperability, and Commonality.
The TCAC PIP will achieve interoperability with MAGTF elements using digital data links and secure voice communications listed in paragraph 6a. This system will conform to the standards contained in the Government Open System Interconnection Profile. (GOSSIP). The TCAC PIP will possess accredited security capabilities for the handling of Special Compartmented Information (SCI) data.
d. Mapping, Charting, and Geodesy Support. The hardware/ software upgrades will promote the use of the latest geographic databases available from the Defense Mapping Agency (DMA).
e. Environmental Support. None required.
7. Force Structure. Seven TCAC PIP systems are required, three for each Radio Battalion and one for the Marine Corps Tactical System Support Activity. No TCAC PIP systems will be included in the Prepositioned War Reserves or on Maritime Prepositioned Shipping. Annex A contains the Life Cycle Cose Estimate (LCCE) for seven TCAC PIP systems.
8. Schedule Considerations
a. The initial operational capability (IOC) for the TCAC PIP will be attained after completion of the systems upgrades, ILS procurement (training, spares, technical publications), and testing. The level of performance necessary to achieve IOC requires one TCAC modified to a final configuration with operators and maintenance personnel trained, and initial spares with interim repair support in place. Full Operational Capability is achieved when all maintenance and repair support, test equipment and spares are in place, all TCACs are modified, and all personnel are trained.
b. The desired time frame for the TCAC PIP capability
is FY96. FY94 appropriation funding is available for the RAWs. Acquisition planning continues, with anticipation of appropriation in FY96 for the remainder of the system.
