Applications

Wideband SATCOM

  • Global Broadcast Service (GBS)
        The GBS is a theater SATCOM system consisting of a primary theater injection terminal connected to a 16-meter dish (transmission antenna) and a steerable patch array, additional theater injection terminals connected to 8-foot dishes (transmission antenna) and a steerable patch array, satellites with steerable downlink spot beams, and user-receive terminals. The GBS provides broadcast services from the CINC to forces in theater. The SSCPAC role in GBS is system engineering, system interface test and evaluation, demonstration of capabilities to fleet customers, and contract monitoring.

  • Super-High Frequency (SHF) SATCOM Systems
        SHF SATCOM systems comprise ground-based transmission terminals, a constellation of satellites, and ship and shore-base receive terminals. SHF SATCOM provide wideband communications services to the Fleet. Current SSCPAC efforts focus on these systems: the current Defense Satellite Communications System (DSCS); the emerging Wideband Gapfiller System (WGS); and the future Advanced Wideband System (AWS). The primary SSCPAC roles in this area are requirements definition, specification writing, and new technology development.

  • Ultra-Small Aperture Terminal
        The goal of this research and development effort, sponsored jointly by the Office of Naval Research and the Advanced Technology Office of the Defense Advanced Projects Research Agency, is to develop K/Ka-band phased array technology for new surface combatants. SSCPAC is developing a prototype hybrid terminal suitable for multi-vehicle technology verification demonstrations in operational environments.

Protected SATCOM

  • Navy Extremely High Frequency (EHF) Satellite Communications (SATCOM) Program (NESP)
        The NESP includes low (legacy), medium, and high (submarine only) data-rate components, a "follow-on" terminal, and advanced EHF equipment. EHF SATCOM provides robust, low-probability-of-intercept communications for Navy ship, submarine and shore facilities. Operational on four satellite constellations (Fleet SATCOM EHF Package (FEP), UHF Follow-On/E/EE, Interim Polar, and Milstar), EHF SATCOM provides global coverage. Applications include secure voice, data, and video, teletype, Mission Data Updates, Air Tasking Orders, Fleet Broadcast, email, and Army Position Location and Reporting System (PLRS) and Extended PLRS data. Primary SSCPAC 552 roles include system engineering and integration, and test and evaluation of EHF SATCOM terminals, and satellites.

Narrowband SATCOM

  • Joint (UHF) MILSATCOM Network Integrated (JMINI) Control System
        The JMINI Control System is the control and management system for all joint Warfighter users of Ultra-High Frequency (UHF) Military SATCOM (MILSATCOM). The JMINI Control System governs the access to these MILSATCOM channels operating in both a single-access mode (one network per channel) and in a multiple access mode (many networks per channel) known as Demand Assigned Multiple Access (DAMA). The Joint Chiefs of Staff have mandated operation in DAMA over all UHF MILSATCOM channels. The JMINI Control System also provides software tools to assist communications officers in planning and scheduling network usage and in assigning the relative priority of this usage over UHF MILSATCOM. The control function of the JMINI Control System is centrally performed within each of four global satellite footprint areas from control stations located at the Naval Computer and Telecommunications Area Master Station at Wahiawa, Hawaii; Norfolk, Virginia; Capodichino, Italy; and at Naval Computer and Telecommunications Station Guam. Each control station houses Radio-Frequency hardware and antenna suites, complemented by computer hardware and software systems, that respond to requests from users throughout the footprint, thereby controlling user access to satellite resources. The management function of the JMINI Control System is distributed among the planners and managers of UHF MILSATCOM, which primarily include the Joint Chiefs of Staff and Unified Commanders in Chief. SSCPAC leads the JMINI Integrated Product Team (IPT) consisting of inter-agency government and industry personnel. 

SATCOM Link Protection 

  • Satellite Communications (SATCOM) Link Protection
        The goal of the SATCOM Link Protection effort is to ensure the ability of the fleet to maintain information superiority by protecting fleet SATCOM links from exploitation and disruption. Potential vulnerabilities of SATCOM systems are identified, modifications to hardware, software, and system operation procedures are developed to mitigate these vulnerabilities, and proposed changes are operationally tested. As part of this effort, systems and procedures are developed to monitor Fleet SATCOM channels for potential disruption from both intentional and unintentional sources, to locate these sources, and to resolve the interference. 

Littoral Communications

  • Digital Wideband Transmission System (DWTS) Support
        DWTS is an L-band, line-of-sight, wideband (2 Mbps) communication system used by the ships of an Amphibious Readiness Group to communicate with each other and with Marines ashore. SSCPAC maintains a full suite of DWTS equipment for system development, application development and shipboard troubleshooting.

  • Battle Force E-Mail 66 (BFEM 66)
        BFEM 66 ensures allied interoperability by providing automatic, secure, error-free delivery of e-mail messages including attached files. E-mail service links the battle group over line-of-sight and beyond line-of-sight paths using High-Frequency (HF) channels.

  • Joint Tactical Radio System (JTRS) & Digital Modular Radio (DMR)
        The JTRS has evolved over many years to address interoperability issues, limited bandwidth, and terminal maintenance costs. The scope of JTRS effort is the combination of acquisition efforts for the next generation software programmable radios. The vision of the JTRS Joint Program Office (JPO) is to develop a family of high-capacity, tactical radios to provide line-of-sight, SATCOM, and beyond-line-of-sight C4I capabilities to war fighters. A software architecture has been developed to address the goal of having one hardware system support multiple applications and waveforms. SSCPAC supports software architecture and waveform development. SSCPAC has the capability to support acceptance, test, and accreditation processes of vendor products for the JTRS JPO including software architecture and waveform compliance. The Digital Modular Radio effort, supported by SSCPAC, is intended to be JTRS compliant.
