Overview of Link 16 System Architecture

Overview of Link 16 System Architecture is designed for engineers, analysts to learn about Link-16 architecture, building blocks and how it works.

Overview of Link 16 System Architecture is a combination of theoretical and practical concepts. Link 16 is a frequency-hopping, jam-resistant, high-capacity data link. Functioning on the base of Time Division Multiple Access (TDMA), where 128 time slots per second are assigned among contributing JTIDS Units (JUs), time slots are prepared into numerous operational Network Participation Groups (NPGs).

Link 16 architecture allows for real-time transfer of combat data, voice communications, imagery, and relative navigation information between dispersed battle elements, using crypto, and frequency hopping.

Link 16 uses Time Division Multiple Access (TDMA) to provide multiple, simultaneous communication paths through various nets. Link 16 communications waveforms are secure and jam resistance. Link 16 provides situational awareness, data throughput and the capacity of information exchanged. Link 16 system architecture provide secure voice capability, relative navigation capability, and precise participant location and identification.

Link 16 data is transmitted via Link 16 terminals with multiple type of platforms with different architecture including JTIDS, MIDS LVT and MIDS JTRS (using SDR). Link 16 terminals are used by aircraft, surface ships, ground vehicles, missile defense systems, networked enabled weapons, and command and control networks.

Who Should Attend?

This course is designed for electronic warfare, avionics systems engineers, system architects, hardware and software engineers, and employees with little or no Link 16 experience. The course is also useful for those who have experience with Link 16 but have never had any formal training on Link 16 system architecture.
