ASX™ Airborne Communications Electronic Surveillance
Embodying our high performance signal processing techniques, the ASX series of COMINT/direction finding systems supports all airborne surveillance platforms. The range gives a high probability of intercept in dense signals environments, and enables the rapid extraction of intelligence from data with advanced filtering techniques.
We have worked with a range of customers to develop airborne Signal Intelligence (SIGINT) systems that deliver the intelligence they need in critical operational scenarios. Built on scalable and modular receiver/antenna architectures, we offer tailored solutions matched to small, medium, and large manned and unmanned platforms, with increasing levels of performance:
AS3 is a compact payload which transforms a tactical UAV, manned utility platform or helicopter into a SIGINT aircraft with minimal modification and expense. AS3 is the fastest route to providing situational awareness to ground forces.
AS4 utilises an array of high-accuracy antennas installed across an airframe, providing a high performance yet compact system for larger UAV and manned platform applications.
AS5 is a full specification system for strategic airborne applications, and may be fitted to a range of platforms such as business jets and large widebody jet aircraft. It is able to intercept high volumes of signals traffic over a vast operational area, with very high accuracy direction finding for geolocation at stand-off ranges.
All ASX systems can be remotely operated by datalink using our innovative bandwidth management technology, and all use our intuitive operator interface, which, for AS3/4 is common to our MEWS Land-based EW solutions.
We also support customers with:
- Trials and calibration to optimise and sustain performance
- System test and airborne trialling
- Operator training
- Platform integration support
- Through-life support.
MEWS™ Land Communications Electronic Surveillance
A high performance spectrum surveillance system for monitoring and direction finding of 2MHz to 3GHz communications, MEWS meets land-based tactical and strategic requirements for monitoring and locating modern threat emissions.
Portable and lightweight, the versatile system scans large parts of the electromagnetic spectrum for RF energy in the form of communications and other electromagnetic signals emitted by adversaries. Connecting two systems by radios enables precise position-fixing of a signal.
As well as detecting, direction finding, exploiting and displaying all signals within a specified frequency range, MEWS uses advanced detection and clustering techniques to locate particular signals of interest for further investigation by operators.
Developed in partnership with L-3 TRL Technology, MEWS combines QinetiQ’s EW signal processing algorithms and software and L-3 TRL’s receiver technology and manufacturing expertise. Integrating lightweight, battery powered components that use software-defined radio and modular hardware gives us the flexibility to offer three variants:
- MEWS-M, man portable and battery powered, for close-in tactical operations
- MEWS-V, readily fitted to vehicles of opportunity
- MEWS-S, high performance Direction Finding and Geolocation – capable of overwatching large areas.
In order to maximise operational effectiveness and minimise training overheads, MEWS presents signals intelligence on QinetiQ’s highly intuitive windows-based ‘Infoviewer’ software, which provides real-time detailed analysis, mapping and filtering.
MEWS is highly robust – able to withstand adverse field conditions including temperature/humidity, dust/sand, and driving rain/immersion.
