Border & Perimeter Security
Integrated counter-UAS protection for borders, remote sites and extended perimeters.
Applications
- Border security
- Remote sites
- Perimeter surveillance
- Mobile patrols

The operating environment
Border and perimeter environments demand awareness across long distances, complex terrain and changing access routes.
Large areas and dispersed sites are difficult to monitor continuously. Low-flying drones can exploit uneven terrain, crossings and surveillance gaps, while operators must coordinate fixed assets with mobile patrols and temporary checkpoints.
Rantelon combines passive RF drone detection, direction-finding data and electronic countermeasures into a layered protection system. It gives teams early warning, a clearer picture of where threats are coming from and response options matched to the operational area.
Sample use cases

Remote perimeter breach
A sensor identifies unauthorised drone activity approaching a remote restricted zone, giving the operator time to direct patrols and prepare a response.

Mobile patrol response
A patrol receives an alert during a border operation and uses portable detection and handheld mitigation to protect the immediate area.

Drone smuggling attempt
Direction-finding data helps security teams understand the drone’s route and identify a likely controller location near a crossing or perimeter.
Key advantages
Long-range early warning
Wide-area RF detection gives operators time to assess threats before they reach a restricted zone.
Passive RF detection
Detect drone and controller activity without transmitting or revealing the monitoring position.
Direction-finding intelligence
Understand approach direction and support the location of a drone or its controller.
Fixed and mobile coverage
Combine permanent sensors with vehicle-mounted, handheld or rapidly deployed systems.
Layered non-kinetic response
Apply targeted jamming and GNSS denial where the situation and rules of engagement allow.
Integrated operational picture
Connect detection and response systems for coordinated protection across distributed sites.
Workflow
Long boundaries and dispersed sites call for a coordinated approach. Shape the system around the terrain, access routes and teams responsible for each area.
Detect
Long-range RF sensors identify drone and controller activity across an extended area.
Locate
Direction finding supports a clearer picture of approach direction and possible controller position.
Respond
Fixed, mobile or handheld systems provide an electronic response at the relevant sector or patrol location.
