The first rigorous try-out of the new Sensor & Trials Facility (STF) was an integrated sensing activity called Salus. Thirty staff from multiple divisions participated in Salus.

Defence scientist Dr Joe Fabrizio, who leads DSTG's research in radio frequency (RF) sensing and electronic warfare, says his team is implementing a bold new vision for the Sensor & Trials Facility (STF) as a collaborative hub with a permanent trials network at its nucleus.
