VT MAK Builds DDS-Based After Action Review Server for Meggitt Training Systems' Next Generation Live Fire Target Systems 

Development of Meggitt’s After Action Review Server Simplified through DDS

Cambridge, Mass., November 30, 2011 - VT MAK, (MAK), a company of VT Systems, Inc. (VT Systems), today announced that Meggitt Training Systems has selected MAK to develop a Data Distribution Service (DDS) based After Action Review (AAR) Server for Meggitt’s next generation live fire (NGLF) target systems. Using DDS as the networking protocol, MAK is developing record and replay capabilities for the system.

Live fire training systems are used to execute realistic scenarios with live ammunition in a simulated environment. The AAR server is an important subsystem that provides feedback on trainee performance. The AAR system will record all the range events communicated via DDS, store them in a SQL database for playback, and assist in analyzing the data to provide training results. Server functionality will enable recording of the DDS data stream, as well as DDS playback/annotation abilities.

DDS is networking middleware is commonly used in embedded systems. It implements a publish/subscribe model for sending and receiving data, events, and commands among the nodes that produce information in the simulation. These nodes, also known as publishers, create ’topics’ (e.g., temperature, location, pressure) and publish ‘samples’. DDS takes care of delivering the sample to all subscribers that declare an interest in that topic.

“We are pleased that MAK has partnered with us to support the innovative capabilities that our next generation live fire target system delivers to the industry. This partnership underpins our mutual commitment to range modernization and the development of future technologies to sustain superior training solutions.”

~ Ronald VADAS,
President, Meggitt Training Systems

“As Live, Virtual, Constructive simulation technologies, C4ISR components, and operation combat systems all merge into the same technology base, it was only natural for K to apply our world-class interoperability expertise to the operational DDS space.  We are delighted to have been recognized by Meggitt as the right partner to develop this turnkey subsystem.
