A Joint Tactical Radio (JTR) set consists of waveform applications, radio hardware, and associated operating environment,
which conform to Software Communications Architecture (SCA).

JTR set hardware, with associated SCA operating environment, includes:
~ Radio Frequency (RF) hardware components
~ Receiver
~ Amplifier
~ Modem
~ Antenna
~ Information Security (INFOSEC) devices
~ Hardware-specific interfaces
~ Operating System (real-time, POSIX compliant)
~ CORBA Common Object Request Broker
~ Core Framework software
~ Associated adapters/drivers used to interface between software and hardware
~ Software including waveform applications, crypto algorithms, protocols, formats, and routers

»Lockheed Martin
~ AMF JTRS radios will interoperate with legacy data and voice circuits used by the U.S., allied or NATO military forces,
~ as well as communicate with civilian first-responder voice and data systems used in disaster relief and other national emergencies.
~ Lockheed Martin completed a live flight demonstration of network centric operations for the Airborne, Maritime and
~ Fixed Stations (AMF) component of the military's Joint Tactical Radio Systems (JTRS).
~ flight demonstration showcased combat-relevant scenarios interacting through JTRS technology.
~ Lockheed Martin's AMF JTRS team funded and executed the demonstration as a risk reduction effort
~ to highlight the technical maturity of the team's solution.
~ Observers at the Pentagon, the Space and Naval Warfare (SPAWAR) System Center in San Diego,
~ and Lockheed Martin facilities in Crystal City, Va., and Goodyear, Az.,
~ witnessed real-time video from the aircraft and communicated in real-time using both new and legacy systems in operational scenarios.
~ sites were also networked directly into the mission network through the government's Defense Research and Engineering Network.
~ airborne nodes, which were flown out of Goodyear, Az., included a United States Army helicopter,
~ a T-39 Sabreliner that represented an unmanned aerial vehicle and a United States Air Force F-16.
~ Ground and aerial nodes interfaced in a dynamic joint tactical Mobile Ad hoc Network
~ using an enhanced version of the Ground Mobile Radio (GMR) Wideband Networking Waveform (WNW),
~ Solider Radio Waveform (SRW) and Legacy Link-16 communications.
~ demonstration did not require unique hardware or proprietary waveforms to integrate ground and airborne assets
~ they ported WNW and SRW on prototype Software Defined Radios to support dynamic routing, streaming video
~ and cross-banding utilizing both IPv4 and IPv6.
~ they are committed to the JTRS vision of an open architecture and network,
~ and cost reductions that are achievable through commonality in non-proprietary software and design.
~ live flight demonstration consisted of eight dynamic segments, each building upon the previous
~ segments focused on the ability to seamlessly integrate the waveforms into an interoperable network
~ to support shared situational awareness information; interoperability between platforms out of line-of-sight;
~ streaming video; and wideband network quality of service.
~ demonstration highlighted an ability to integrate WNW/SRW-enabled nodes and legacy aircraft with Link-16 communications
~ to theater applications like the Theater Battle Management Core System, Distributed Common Ground System and Joint Tactical Observation systems
~ Lockheed Martin AMF JTRS team is currently under contract for Pre-System Development and Demonstration (Pre-SDD) phase of AMF JTRS competition
~ AMF JTRS program is expected to be awarded in February 2007
~ Lockheed Martin team includes BAE SYSTEMS, General Dynamics, Raytheon and Northrop Grumman
~ AMF JTRS program will deliver a suite of software defined, multi-function radios for use throughout the Department of Defense,
~ as well as potential use in the Department of Homeland Security
~ A single radio will be capable of operating on highly secure, high performance military tactical networks in net-centric operations.
~ AMF JTRS radios will interoperate with legacy data and voice circuits used by the U.S., allied or NATO military forces,
~ as well as communicate with civilian first-responder voice and data systems used in disaster relief and other national emergencies.
