A coordination-based measure of team situati situation awareness is presented and contrasted with on knowledge-based measurement. The measure is a applied to team awareness of a communication pplied channel failure (glitch) during a simulated unm unmanned air vehicle reconnaissance experiment. anned Experimental results are reported, including the findings that not all team members should be identically aware of the glitch and that appropriate levels of coordination are an important precursor of team situation awareness. The resu results are discussed in terms of the application of lts coordination metrics to support the understanding of team situation awareness. The use of team coordination as a low-dimension variable of team functionality is scalable over a variety of team sizes and expertise distributions.
