Spectrum Situational Awareness at Sea

Peraton Labs’ SecureSense™ spectrum monitoring device was successfully trialed on a Long Range Unmanned Surface Vessel (LRUSV) System in conjunction with the U.S. Navy’s Unmanned Integrated Battle Problem (UxS IBP) 21. This U.S. Pacific Fleet exercise, executed by U.S. 3rd Fleet from April 19-26, 2021 in San Diego, California, was designed to integrate manned and unmanned capabilities into operational scenarios to generate warfighting advantages. The LRUSV System is part of a new era of naval technology involving a network of unmanned vessels traveling autonomously for extended ranges and transporting loitering munitions to address targets at sea and on land.

SecureSense provides affordable, real-time intelligence to monitor spectrum usage, rapidly identify unexpected emitters and efficiently support mission needs. Leveraging inexpensive commercial-off-the-shelf (COTS) hardware—along with leading-edge sensor technology, high-reliability management system, novel signal processing techniques and innovative data analytics capabilities—SecureSense achieves more accurate spectrum situational awareness at significantly lower cost and in the most demanding environments.

SecureSense interiorIn the proof-of-concept trial, a SecureSense sensor was adapted for standalone operation and physical installation on an LRUSV, including mounting, powering, and water and salt spray resistance.  During three days of at-sea maneuvers, the SecureSense device continuously and autonomously monitored frequencies from 700 MHz to 2700 MHz, without causing any interference with other exercises or requiring any attention or servicing. The SecureSense device operated in a standalone mode, without real-time interaction with other sensors, the system server or users, and the collected sensor data was off-loaded and analyzed after the event.

The proof-of-concept successfully demonstrated the ability of a ruggedized SecureSense device to operate on the LRUSV, including connecting the device to the on-board local area network for proxied access to the vessel’s satellite communication (satcom) link and establishing secure access to the sensor while at sea.  Future investigations of SecureSense for littoral and at-sea environments would address applications for signal detection and classification, use of satcom for targeted low-bandwidth communications and alerting, and multi-sensor deployments with sensor-to-sensor coordination.
