AT-620 Portable Integrated Drone Detection & Countermeasure Device
AT-620 Portable Integrated Drone Detection & Countermeasure Device
The AT-620 is a fully integrated handheld drone detection and countermeasure device designed with no external
attachments, allowing soldiers to carry and operate it with ease. It supports 3 km omnidirectional detection
and 2 km directional countermeasures against a wide range of UAV threats, including DIY FPV drones and
conventional UAV models.
Equipped with SDR-based jamming technology, the device covers multiple communication bands and provides
reliable suppression of drone control, data links, video transmission, navigation signals, and other channels.
With a built-in visual-aided targeting system, the AT-620 enables continuous 360° detection, identification,
and positioning of drones, forcing them into failsafe behaviors such as hovering, retreating, or landing.
Key features
- Integrated design: Handheld, single-piece design with no external accessories; lightweight and field-ready.
- Flexible jamming: SDR-based multi-band jamming against DIY FPV drones and common UAV communication links.
- Full-band suppression: Covers domestic and international UAV bands, providing effective disruption, return-to-home induction, and forced landing.
- Visual-aided targeting: Built-in assistance system improves aiming accuracy and enables real-time target recognition and tracking.
- Customizable jamming: Supports personalized jamming configurations and user-defined jamming modes.
- Future-proof SDR architecture: Algorithm upgrades ensure long-term effectiveness against evolving drone technologies.
