About Silentium Defence
Silentium Defence is an Australian passive radar company, co-founded in 2017 by Dr James Palmer, that has grown past 100 staff serving defence and space customers in Australia, the United States, and other allied nations. Its OMNIGUARD product applies passive radar — detecting objects from reflected ambient radio and television transmissions rather than emitting its own signal — to space domain awareness, providing continuous, low-latency tracking of catalogued and uncatalogued resident space objects, debris, and re-entry vehicles in low Earth orbit without requiring a spectrum license.
The company markets OMNIGUARD as a fixed-site or relocatable SDA sensor, positioning it as a lower-cost, covert alternative to active radar and optical tracking networks for allied space surveillance coverage.
