Rockwell Collins is leveraging our mission computing technology, along with our communications and navigation experience, to facilitate Network-Centric Operations (NCO) and provide improved situational awareness for ground users and platforms. Our role in developing the Ground Mobile Radio (GMR) as part of the Joint Tactical Radio System (JTRS) program provides us with the expertise to meet the communications and interoperability demands of the warfighter. In the area of net-centric computing, we have gained extensive knowledge from our participation in developing Integrated Computing Systems (ICS) for Future Combat Systems (FCS). Our Net-Centric Computer System (NCS) also provides advanced computing capabilities and can be applied to a wide variety of existing platforms, including tracked, wheeled and airborne vehicles.
