Critical infrastructure · civil sites
Drone detection beyond the perimeter.
Fravek is developing a passive detection service for critical sites, delivered through security integrators. Our approach combines distributed sensing nodes with software to help operators detect approaching drones and cue existing security systems.
Who’s watching over the fence?
The intended service
Through the security partners you already work with.
Fravek
Detection as a service
Passive sensing nodes plus software, intended as an ongoing service rather than a one-off box.
Security integrator
Delivers and supports it on site
Owns the customer relationship, the alarm centre and the field teams, and can add drone detection to existing contracts.
Site operator
Already buying security
Airports, energy sites, ports, water utilities and data centres looking for more awareness of the airspace above them.
Additional low-airspace awareness
An extra layer above the fence line.
- · Cameras and acoustics reach a few hundred metres and generally need something else to cue them first.
- · Active radar can cover wide areas, but involves transmission, spectrum clearance and a significant installation per site.
- · Our nodes receive existing radio signals instead of transmitting, which is what makes distributed placement around a site practical.
- · Supporting context: the EU CER directive and NIS2 push operators of critical sites to manage physical risks, and unauthorised drone activity is named among them.
Why earlier matters
Seconds
Short-range sensors typically report once a drone is already close to the site.
More time
Wide-area awareness is intended to give operators time to verify and prepare a response.
Integration with existing operations
Built to fit the security operation you already run.
Cue existing sensors
Point the cameras
Detections are intended to direct cameras and other sensors towards the right sector for closer inspection.
Operational systems
One picture, not one more screen
Software is being developed to deliver tracks into command-and-control and security management systems already in use.
Siting
Receive only
Because the node does not transmit a radar signal, placement on rooftops and masts is simpler than for an emitting installation.
What a site pilot would evaluate
Agreed measurements, not assumptions.
- · Signal conditions and node placement at the specific site
- · Detection performance against agreed drone types and flight profiles
- · Coverage achieved with a given number of nodes
- · How detections reach the alarm centre and operator workflow
- · Integration with existing cameras and security systems
- · Practicalities of installation, power and connectivity
Technical architecture and evaluation details are available to relevant organisations on request.
Coverage illustration
Coverage scales with the number of nodes.
Larger airframes reflect more signal and can be seen further out; smaller drones need a denser network. How many nodes a site needs depends on its geometry and the drone types it cares about, which is exactly what a pilot is meant to establish.
Illustration only. Node placements and coverage are indicative until a site is surveyed.
Long-term direction
From one protected site to a shared sensing network.
A single site proves the concept. The longer-term direction is a city-scale or regional network: nodes on many sites, owned by different operators, contributing to a common air picture that no single actor has to buy or operate alone.
- Nodes across many protected locations
- Multi-site
- One picture, fused across operators
- Shared
- Intended as a detection service
- Service
