EM-Vis Locate
Enable super resolution direction finding and monitor global High Frequency (HF) communications with Strategic Signals Intelligence (SIGINT) coverage you can trust. Deploy networkable, fixed arrays for persistent collection or integrate with mobile EM-Vis Locate-T systems for comprehensive spectrum awareness.
Achieve persistent HF spectrum monitoring through operationally proven systems deployed globally. Support strategic Signals Intelligence operations with reliable, continuous collection capabilities.
Strategic Intelligence Without Borders
HF is a communications medium that supports resilient global communications. With increased global instability and operations at reach, HF is experiencing a renaissance as peer conflicts drive the need for assured long-range connectivity. EM-Vis Locate is a direction finding system that provides fixed, strategic surveillance across the entire HF spectrum, delivering 24/7 global coverage from safe countries and locations.
EM-Vis Locate can be complemented by other, tactically deployable systems via Roke’s common Electromagnetic (EM) visualisation tool (EM-Vis Review) to provide full spectrum signals intelligence to military, government agencies and other intelligence organisations.
How EM-Vis LOCATE benefits you
-
Pinpoint accuracy
High-precision direction finding within 1 degree RMS across elevation and azimuth planes.
-
Global reach
Monitor worldwide HF skywave and shorter-range ground wave signals from strategic, safe locations.
-
Superior signal processing
Proprietary Super Resolution Direction Finding (SRDF) algorithm provides optimal performance in contested/congested Electromagnetic Environment (EME).
-
Selective beam control
Adaptive Digital Beam Forming (ADBF) allows operators to steer collection on Signals of Interest and null sources of interference.
Need forward deployment?
EM-Vis Locate can be complemented by Roke’s deployable, EM-Vis Locate-T system.
EM-Vis Locate-T replicates the same proven technology as EM-Vis Locate but in a mobile, rapidly deployable configuration.
For wideband line of sight surveillance, EM-Vis Perceive provides high mobility Electromagnetic Warfare capability fully integrated with EM-Vis Review to enable shared situational awareness and Electromagnetic Environment (EME) visualisation.
FAQs
HF is an enduring, effective and resilient long-range communications bearer in-service with the majority of global Armed Forces.
Roke’s bespoke HF modelling software works harmoniously with HF sensor hardware to provide an alternate, mathematically driven geolocation tool.
Super Resolution Direction Finding is an advanced processing technique that identifies true signal bearings particularly in contested/congested operating environments.
Adaptive Digital Beam Forming allows semi-automated electronic steering to focus antenna gain towards signals of interest or creates nulls to suppress unwanted signals.
Fixed installation allows 24/7 monitoring with larger antenna arrays that increase Direction Finding accuracy at stand-off ranges.
EM-Vis Locate provides strategic fixed HF Signals Intelligence infrastructure, while EM-Vis Locate T offers tactical flexibility as a deployable, mission-specific system.
