New funding for space traffic radar

Silentium Defence has secured a $3.2 mio contract from the Australian Department of Defense to advance, deploy and demonstrate its passive radar system for monitoring traffic in space. The funding comes in the $28 mio latest round of industry grants from the Defense Innovation Hub.


Designed and developed in Adelaide, South Australia, Silentium’s MAVERICK S-series is the first commercial-scale passive radar system for surveillance of space and will provide persistent detection and tracking of objects in low-earth-orbit to support space traffic management. The system requires no spectrum allocation to operate and it can detect and track objects and measure rate of movement in low earth orbit regardless of weather, visibility, or time-of-day, The Lead portal reports.

The Wingfield-based company also announced in June it would lead a project to build a multi-sensor space observatory in remote South Australia. That project, in collaboration with Western Sydney University, was also awarded $1.46 mio through the Australian Space Agency in June.

Silentium Defence CEO Dr James Palmer said the latest contract win showed that “Defense recognizes the risk posed by the increasingly congested and contested space domain.” He said the passive radar would be powerful but low-power, accurate and agile enough to deliver a transformative capability for the Australian Defense Force and its allies.

Satellite systems are vulnerable to space debris and advanced counter-space capabilities which can deny, disrupt and destroy our space-based systems,” Palmer said. “Safe and assured access to this critical domain is predicated on availability of high-quality, real-time data to inform decision making. That is what the MAVERICK S-series will deliver, and we’re delighted to further advance the system using local skills and local technology with support and input from Defense.”

The contract will see Silentium Defense move from its successful completion of Phase one to the start of Phase two deployment under the Defense Innovation Hub program.The observatory is expected to be  completed next year and is being built near the River Murray town of Swan Reach, 160 km northeast of Adelaide and on the edge of South Australia’s only officially sanctioned International Dark Sky Place.

Another South Australian company, Prism Systems, also received a $925K grant in the funding round towards developing and demonstrating an integrated capability solution for the Royal Australian Navy. The innovation seeks to improve the efficiency and effectiveness of ship and aviation system integration flight trials through automating processes, analysis, recording, and reporting of data.

South Australia is also home to major Tier 1 defense companies and several emerging space startups, including Fleet Space Technologies, Inovor Technologies and Myriota. Minister for Defense Industry Melissa Price said the latest contracts provided Australian businesses with opportunities that could enhance defense capability. The Australian Government’s goal is to triple the size of the nation’s space sector to $12 bln and create an extra 20K jobs by 2030.
