Case

Large-scale sports events, marathons, and mass gatherings feature dense crowds, long routes, and high public attention. In recent years, unauthorized drone flights (“black flying”) have become a critical security risk—threatening public safety, unauthorized surveillance, object throwing, and event disruption. Low-altitude airspace security has become an indispensable part of modern event security systems.

This article shares a practical, field-proven low-altitude security solution for large sports events and marathons, supporting full coverage, batch drone detection, intelligent identification, rapid countermeasure, and safe disposal in crowded scenarios.

Core Security Requirements for Large Events

To ensure airspace safety throughout the event, the solution must meet these key goals:

• Cover the 1–3 km low-altitude range above the track, venue core area, and surrounding zones
• Support batch detection & identification of drones, distinguishing authorized and rogue targets
• Enable rapid networked countermeasures with real-time alerts and collaborative disposal
• Ensure zero electromagnetic interference with public communications, broadcasts, and on-site command systems
• Adapt to dense crowds, long linear routes, and mobile security patrols

Recommended Product Portfolio (Field-Proven)

Our integrated solution combines four core devices to form a closed-loop detection–identification–countermeasure system:

1.Detection and deception integrated device (ZY100-GTB)

2.Drone detection team equipment (ZC400-GTA)

3.Drone detection countermeasure shield (ZG400-GTA)

4.Navigation deception device (YP100GTB)

This combination delivers full coverage, multi-dimensional perception, and precise disposal without disrupting event operations.

Step-by-Step Deployment & Operation Process

1.Linear Route Coverage (Along the Race Track)

• Deploy ZY100-GTB every 500 meters along the marathon route
• Achieve 500m detection + 1,500m countermeasure range
• Support white/blacklist auto-recognition: allow authorized aerial drones; automatically deceive and divert rogue drones

2.Mobile Patrol & Team Collaboration

• Security teams carry ZC400-GTA portable detection equipment
• Host unit + wristband terminal for 1.5km omnidirectional monitoring
• When team distance ≥ 1 km, trigger linked alarms and share target positions in real time
• Improve response efficiency and eliminate blind spots

3.Key Node Guard (Entrances & Critical Sections)

• Deploy ZG400-GTA shields at venue entrances, bridges, and high-risk sections
• 360° omnidirectional detection + ≥2 km countermeasure
• Independent interference of communication and navigation signals; quick repel or forced landing
• Lightweight, handheld, ideal for fixed duty and mobile response

4.Core Area Closed Protection

• Deploy YP100-GTB navigation deception equipment in the event core zone
• Conduct GPS/Beidou/GLONASS multi-system deception
• Simultaneously counter ≥30 drones; support 8-directional guided departure
• Form a safe low-altitude “protective circle” for the venue

Practical Effects & Performance Highlights

• Full coverage: Networked deployment covers the entire activity area with no blind zones
• High efficiency: Deception response time < 3 seconds; simultaneous disposal of multiple rogue drones
• Safe & non-intrusive: No harmful electromagnetic radiation; no interference with public networks or broadcasts
• Smart management: Auto white/blacklist; visual command; clear accountability
• Field-proven: Stable operation in crowded, long-route events; zero security incidents

Conclusion

For marathons, championship games, and large-scale public events, low-altitude anti-drone security is no longer optional but mandatory. Our networked, multi-device integrated solution provides reliable airspace protection through full coverage, precise identification, rapid response, and safe disposal—helping organizers mitigate drone risks and ensure smooth event delivery.
