LiskFence Solutions Tailored for Multi-Scenario Counter-UAS Operations

LiskFence notes that unmanned systems—now fielded by near-peer militaries and terrorist actors alike—have become the asymmetric tool of choice for swarm or single-unit payload strikes and battlefield surveillance, driving demand for multi-scenario counter-UAS coverage.

Safety Risks

THREAT TYPES
Physical Damage
• UAS collide with high-voltage lines, causing short circuits.
• Suspended wires, Molotov bottles or other foreign objects are dropped onto tower bases.
• Crashes into substation battery banks trigger secondary disasters.
Information Theft
• Low-altitude photography of substations, converter stations and line corridors to steal high-precision 3-D data.
• Recording of inspection routines exposes equipment defects and operational weaknesses.
Operational Interference
• Illegal flights disrupt emergency repairs during peak-summer or Spring-Festival guarantee periods.
• Unmanned platforms lose control in strong magnetic fields and collide with inspection robots, delaying fault location.

REGULATORY CHALLENGES
Coverage Gaps
• Transmission lines run in linear corridors across mountains and uninhabited areas; fixed sensors provide limited reach, leaving blind zones in deep valleys and river crossings.
• Substations are adjacent to residential zones, so counter-UAS measures must avoid interference with civilian communications.
Identification Difficulties
• Rain and fog sharply degrade electro-optical recognition; birds, kites and drones are hard to distinguish.
• Equipment must strictly avoid power-industry bands such as 230 MHz, complicating parameter tuning.
Emergency Response Hurdles
• Sudden illegal flights in mountainous areas require long foot-marches with portable equipment.
• Failure of fixed systems leaves no back-up detection, undermining continuous protection during guarantee periods.
Abilities

Full-Chain Closed-Loop Control
Precision Spoofing & Countermeasures
• Full-Chain Closed-Loop Control
– Fuses radio-spectrum sensing (sniffing weak UAV emissions), packet-protocol reverse parsing (typing non-cooperative drones) and comm-protocol decoding.
– Covers the whole plant plus a 3 km buffer.
– Delivers:
1.Pre-event early warning (advance detection)
2.Mid-event tracking (real-time trajectory plotting)
3.Post-event back-tracing (pilot geo-location)
Information Theft
• Precision Spoofing & Counter-UAS
– Radiates counterfeit GNSS signals to fool the UAV into hovering, forced-landing or returning home.
– One-to-one jamming; zero impact on nearby power/communication gear.
– Transmit power tailored to national regulations – full compliance on record.
Full-Chain Closed-Loop Control
• Customizable Back-End
– Global device health board, multi-dimensional flight-event analytics, auto-generated subject reports, multi-level user rights.
– Plug-in development for power-security missions.
Customizable Backend
• No-Dead-Zone Surveillance Grid
– Fixed stations: 80 % of substations & key towers.
– Vehicle-mounted patrol: along transmission lines, fills 15 % blind spots (mountains, river spans).
– Man-pack sets for emergency response: final 5 % ad-hoc threats.
Seamless Detection Deployment
• Fixed equipment covers 80 % of substations and key tower bases.
• Vehicle-mounted mobile units patrol transmission corridors, filling 15 % of blind spots in mountainous and river-crossing zones.
• Inspection personnel carry portable devices for last-mile response to the remaining 5 % of emergent threats.
