Joint Combat Information Terminal (JCIT) Software
The JCIT is a multi-band, multi-functional radio terminal with programmable modulation and demodulation, information security (INFOSEC) (including transmission security (TRANSEC), communications security (COMSEC) and computer security (COMPSEC)), link and message processing and user interface capabilities. The JCIT is designed to be fully interoperable and be compatible with the Army Tactical Command and Control System/Army Battle Command System (ATCCS/ABCS). The JCIT is being designed to easily integrate on hosts other than the A2C2S and to be easily extended to the support of new waveforms. The plan for integrating new wavetrains into JCIT is to adapt the operational designs of developers external to the JCIT program into the JCIT infrastructure. This drives the JCIT software design to be built around open, popular standards. The contractor shall utilize it’s expertise in JCIT environment, a PowerPC 603e processor running the VxWorks. For additional information on the JCIT, refer to the Prime Item Development Specification for the Joint Combat Information Terminal (JCIT).
The contractor shall participate
in the requirements definition, software design, unit testing and integration
for: the low level task to task communications and resource management
across the modules; the SINCGARS/SIP waveform processing, including development
of error correction algorithms such as Reed-Solomon and Nadler encoding
algorithms; and the testing of the multiple waveforms being integrated
into the JCIT. In developing the software, the contractor shall follow
standards designed and documented in the JCIT Application Programmer’s
User Manual (JAPUM)
JCIT Testset - The User Console
To adequately test the JCIT
radio, a test fixture is being developed. The JCIT Testset has several
configurations which to allow it to adapt to the test requirements of each
module developer and to be used for single and multiple waveform integration
and testing.
The JCIT Module Tester has two varieties, the JCIT Integration Motherboard (JIM), and the JCIT Integration Motherboard Break Out Box (JIMBOB). The JIMBOB is a full-function JCIT Module Tester which has backplane slots with switched and measured currents and voltages. The JIMBOB contains seven FPGAs to control switch closures and voltage and current monitors. The FPGA interfaces with the User Console using the PC’s Extended Parallel Port (EPP). The JIM is a smaller less capable interim test device tool. The contractor shall support the NRL by populating the User Console chassis from the component lists and by integrating and testing the multiple hardware components as a complete system. More information on the JCIT Testset is available in the JCIT Testset Software Design Document.
Since multiple JCIT test fixtures (11) are planned to be built and distributed to waveform developers and integration facilities, ICS is providing phone support for the User Console and JCIT Testset (and where required on-site support).
ICS is using the SCL product and toolset to provide a scaleable, scripted testing capability for the JCIT. ICS is working with the NRL and other contractors to define the object database to support the testing of the JCIT. ICS is utilizing the SCL system to create an Application Database from which to generate packets to be placed directly on the 1394 bus. Additionally, ICS is defining and implementing the SCL applications necessary to provide the adequate interfaces to the external JCIT test equipment such as a 1394 interface, a 1553B interface, GPIB interface, an EPP interface, and multiple serial interfaces to monitor and control various test points in the system. ICS is developing and maintaining software applications used for the test and checkout of specific waveforms for the JCIT. ICS is also developing and maintaining software used for built in test and programming of PCI 1394 interface cards.
ICS is supporting the testing effort on the JCIT and its integration with the Workstations to form the A2C2S. The integration and testing of the system includes inputs to the System Test Plan, the Acceptance Test Plan/Procedures and the Qualification Test Plan/Procedures.
Tactical Environment Simulation
To adequately simulate the data traffic and digital message types that are utilized in the tactical communications environment, ICS is supporting automated message generation based upon a force-on-force constructive simulation tool. The tool utilized during the prototyping stage of A2C2S, the Task Force XXI, was the Modular Semi-Automated Forces (ModSAF) tool. The automatic generation of DIS-compliant Protocol Data Units (PDUs) by ModSAF provides the inputs to the simulation tools which massage the data formats into the types expected by the A2C2S Workstations, such as the United States Message Text Format (USMTF), the Variable Message Format (VMF) and the Air Force Applications Program Data (AFAPD). The contractor shall provide an SCL Application Database to provide additional digital message simulation capabilities for digital messages processed by the JCIT. To provide a high level of simulation configuration and control, the contractor shall utilize the SCL scripting capabilities for building test scenarios and sequencing of message and data.
Advanced Warfighter Experiment (AWE) Support
ICS has supported the NRL as the systems are deployed to the field. This support includes operational periods where ICS is actively engaged in the operations of the systems during simulated or practice missions. On occasion, ICS is required to support the platform while in the field and airborne.
