The hotter the low-altitude economy gets, the faster illegal drone flights become.
As rogue drones evolve from “leisurely aerial photography” into modified FPV racers that skim past buildings at 300 km/h, the awkwardness of conventional low-altitude security has become obvious: radar can see them, jamming guns cannot reach them, and ordinary multirotors cannot catch them.
The first principle of low-altitude defense is being rewritten. It is no longer “detect and neutralize,” but “only what you can catch up with can be neutralized.”
I. Why a “High-Speed FPV” Product Line Is Needed
The traditional three-pronged counter-drone approach — radar, jamming, and spoofing — still works in slow-moving, open scenarios. But against a new generation of high-speed rogue flights, three cracks appear:
- Cannot catch up: security multirotors cruise at 60–80 km/h, while a modified FPV starts at 300 km/h the moment you touch the throttle.
- Cannot jam accurately: fiber-optic FPV drones do not rely on GPS, so spoofing fails; high-power jamming in cities easily disrupts surrounding communications and navigation.
- Cannot retain evidence: “chasing away” is not “neutralizing.” With no trajectory, no imagery, and no traceability, the enforcement loop breaks at the very last step.
A genuinely mature low-altitude defense capability must follow this chain: detection (radar / electro-optics) → identification (AI vision) → high-speed approach (FPV effector) → tracking, escort flight, and soft neutralization → video evidence for a closed loop.
What Foshan Null Space Innovation Technology (NULL SPACE) builds is precisely the link in that chain that “runs, chases, and locks.”
II. The Peregrine LKHB Series: The High-Speed Effector Layer of Low-Altitude Defense
Null Space’s in-house Peregrine (YouSun) LKHB series of high-speed FPV drones is positioned neither as a consumer camera drone nor as a fixed-point jammer box, but as:
- an “aerial rapid-response unit” that launches on radar alert
- a “peer-adversary platform” against high-speed rogue flights
- an “end-of-chain closed-loop effector” for key-site protection
- a “high-speed live-fire target” for counter-UAS teams
The core logic comes down to three words: fast, accurate, stable.
1. Fast: Speed Is the Threshold for Countering High-Speed Rogue Flights
| Model | Top speed | 0–100 km/h acceleration | Video / RC link | Endurance | Role |
| LKHB-1.5 | 350 km/h | ≈1.3 s | 5 km | 3 min | Single-operator rapid response / close-range emergencies |
| LKHB-5 | 380 km/h | ≈1.4 s | 8 km | 8 min | Routine duty at industrial parks and campuses |
| LKHB-30 | 400 km/h | ≈1.5 s | 35 km | 10 min | Flagship for airports / defense in depth |
The entire lineup offers Beaufort level-8 wind resistance, an operating range of −10 °C to 40 °C, and a service ceiling of 5,000 m. This is not “flies beautifully in a lab,” but “actually reports for duty” in wind and rain, against backlight, and inside high-EMI industrial parks.
2. Accurate: AI Vision Lets It “Fly Fast” and “Lock Hard” at the Same Time
- For targets of ≥16×16 pixels: detection rate ≥95%, recognition accuracy >85%, false alarm rate ≤5%
- Tracks micro-targets as small as 3×3 pixels, with anti-shake and anti-occlusion capability and fast re-acquisition after brief loss
- AI dynamic tracking supports moving targets of up to 100 km/h
- Optional 640 or 720×560 uncooled thermal imaging for day-and-night, all-weather operation
- H.264/H.265 encoding with low-latency RTSP streaming, connecting directly to command displays and low-altitude management platforms
What the operator sees is not a “centered image,” but a predicted trajectory plus active follow-flight. Whether the intruder hugs walls, dives under bridges, or escapes into backlight, the Peregrine stays on it.
3. Stable: Industrial-Grade Links — No Blackouts Means Truly Industrial-Grade
- 915 MHz + 2.4 GHz dual-band control, optional 5.8 GHz video, with separate RC and video links
- Automatic link switching in complex electromagnetic environments — no disconnection and no blind flight at substations, airport perimeters, or chemical tank farms
- Modular quick-release structure: swap a module after a crash and training continues; redundant power with controlled descent after a single-motor failure
III. The Falcon Line: Two Sides of the Same Coin — Racing and Hard Interception
Beyond the Peregrine defense line, Null Space’s Falcon series of high-speed FPV / interception configurations targets even more extreme confrontation scenarios:
- 7-inch standard version exceeds 460 km/h top speed and reaches full speed in 10 seconds
- Pure kinetic impact interception: no explosives, no smoke or fire, no secondary fragment risk
- Visible-light plus infrared dual-mode AI guidance, with fire-and-forget capability
- Multiple deployment forms: single-soldier ejection, vehicle-mounted, and fixed sites
The Peregrine is responsible for “catching up and closing the evidence loop”; the Falcon is responsible for “catching up and hard neutralization.” Both lines share the same in-house flight-control and link technology stack — one training program, one spare-parts pool, one O&M system.
IV. Real-World Deployments: Solving Real Pain Points, Not Just Looking Good on Paper
Airport clear zones: radar detects → LKHB-30 launches → dual-sensor lock-on → escort-and-expel with full video recording. No crude suppression; the logic complies with clear-zone regulations.
Chemical, power, and oil & gas hubs: LKHB-5 as the mainstay, with level-8 wind resistance and redundant links. AI distinguishes birds, kites, and drones with a false alarm rate ≤5%; audible-visual warnings, blocking maneuvers, and evidence collection follow a soft-approach-first principle.
Large events and exhibitions: LKHB-1.5 is carried and launched by a single operator, airborne on ejection, establishing response capability over a temporary airspace within 3 minutes.
Counter-UAS range training: authentic 350–400 km/h simulation of modified FPV threats; red-blue confrontation, radar integration, and net-capture coordination all trained in one place.
FPV racing and chase training: a high-speed airframe with low-latency video — both a racing platform and a “high-speed sparring target” for counter-UAS teams.
V. Why Null Space
- Rooted in Foshan, with in-house R&D and manufacturing in the Greater Bay Area: flight control, propulsion, AI vision, and airframes all developed in-house
- The Peregrine and Falcon lines together cover both “training” and “security,” lowering customers’ total cost of ownership
- Support for complete-aircraft delivery, OEM/ODM customization, and protocol integration with radar and electro-optical platforms
- On-site testing, live training, and rapid maintenance at the Foshan base, with short prototype iteration cycles
- Brand creed: Protect · Precise · Reliable
Low-altitude security is not about “whoever is fastest wins,” but about being fast within the rules, accurate under control, and traceable in every response.
VI. Compliance Boundaries (Must Read)
The Peregrine and Falcon are positioned as special equipment for low-altitude protection and emergency response, intended for airport groups, energy/power/chemical industrial parks, military and government key sites, public security and security-system integrators, counter-UAS training bases, and organizations holding the necessary airspace qualifications.
Actual deployment requires confirming in parallel:
- Airspace approval and flight safety radius
- Rules of engagement (soft expulsion and evidence collection first; net capture or kinetic response as needed)
- Protocol integration with existing radar, electro-optical, and command platforms
- Insurance, after-sales support, and test-flight validation mechanisms
