JPEO JTRS and ViaSat Successfully Demonstrate SATCOM Interconnect to JTRS Network

CARLSBAD, Calif., Dec. 13, 2010 /PRNewswire/ -- The Joint Program Executive Office (JPEO) for the Joint Tactical Radio System (JTRS) and ViaSat Inc. (Nasdaq: VSAT) have successfully demonstrated the ability to integrate commercial mobile SATCOM networks with JTRS networks. This integration allows the commander to interconnect dispersed field forces using JTRS radios and then backhaul communications to command centers or any other locations, including mobile locations, throughout the globe. The capability has the potential to interconnect air, land, and sea forces into an integrated tactical network for shared situational awareness and the distribution of voice, video, or sensor data within theater or around the world for real time decision making.


Today, tactical communications are dominated by line-of-sight links, so mountain ranges or other physical obstacles block communication between units. While JTRS radios have the ability to emulate a wide variety of current force radios, they also implement IP-based networking for increased data throughput over self-forming, self-healing, managed networks, thereby increasing range and reliability of communications and data exchange. The integration of SATCOM on-the-move capabilities, including the ViaSat ArcLight® system or LinkWayS2™ current force modem, extends the range and reliability even further.

The demonstration attached a commercial broadband on-the-move satellite modem to the JTRS software defined Ground Mobile Radio (GMR). The system architecture included the JTRS developed Wideband Networking Waveform performing as a local wireless network, with the worldwide ViaSat Yonder® Ku-band mobile broadband network as the beyond line-of-sight link secured with the new ViaSat AltaSec® IPS-250, a non-CCI, Suite B inline network encryptor.

“The commander’s intent for JTRS is to provide seamless, interoperable communications from brigade command to squads and teams. Today we have shown this interconnection between primarily localized JTRS networks and the global reachback provided by SATCOM to battalion and brigade command. In dispersed deployments like Iraq and Afghanistan, units are often extended beyond line-of-sight and are subject to blockage due to mountains and other structures. Integrating SATCOM with JTRS networks bridges that gap and puts these units back in touch with each other and with central command,” said Ric VanderMeulen, VP Global Satcom Systems, ViaSat Inc., commenting on the successful test.

The Joint Tactical Radio System (JTRS) has evolved from a loosely associated group of radio replacement programs to an integrated effort to network multiple weapon system platforms and forward combat units where it matters most – at the last tactical mile. In 2005, JTRS was restructured under the leadership of a Joint Program Executive Officer (JPEO) headquartered in San Diego, California. The JPEO JTRS provides an enterprise acquisition and management approach to successfully and efficiently develop, produce, integrate, test and field the JTRS networking capability.

By developing and implementing an open architecture of cutting–edge radio waveform technology, multiple radio types (e.g., handheld, ground–mobile, airborne, maritime) are now capable of communicating with one another. The ultimate goal is to produce a family of interoperable, modular, software-defined radios that operate as nodes in a network. These radios enable secure wireless communication and networking services for mobile and fixed forces, consisting of joint, U.S. Allies and coalition partners, and in time, disaster response personnel.
