The result of this fusion process is that only data essential to the overall tactical picture is received by all end users. Data that is user-specific is transmitted only to the individual units that require it. This frees bandwidth that would have otherwise been filled by information extraneous to the big picture. At the core of TCN technology are a number of generic software applications that enable independent component support of individual sensor systems. Unlike the single CEC network architecture, the TCN scheme combines a variety of networks to create a common frame track picture that coordinates data users.
Information is transmitted according to the level of track accuracy needed at user end points.
Data accuracy levels are determined by track identity, type, category and geographic location. This determination is based on the state of a particular track, be it situational awareness, tactical or engagement. The TCN process involves several stages. At the element-server level, data are correlated, associated and tracked once received from local sensors. What are referred to as associated measurements of each track are returned to the appropriate sensors for dimensional verification.
