FPV drones have become one of the main challenges of modern warfare. They are fast, maneuverable, and capable of delivering a precise strike at minimal cost to the enemy. Their effectiveness is based on surprise — the operator guides the drone toward a target almost undetected, and physical detection occurs only in the final seconds.
To provide the ability to react to a threat in a timely and advance manner, Ukrainian company BlueBird Tech developed the portable drone detector “Chuyika.” The device was first presented in 2023, and the “Chuyika 3.0” modification has since become one of the most widespread models at the front according to the manufacturer: it is used by more than two dozen units, as well as volunteers, journalists, and even agricultural workers operating in frontline zones.
How “Chuyika 3.0” Works
The device operates on the principle of passive radio interception. It does not emit its own signals, but only captures analog signals in the most common frequency bands used by FPV systems. This does not expose the operator’s position and can warn of FPV drone activity before it is visually detected (provided the drone uses analog video transmission and operates in a supported frequency range).
- Response speed — a full scanning cycle takes 4–8 seconds.
- Detection range — up to 4 km in open terrain (with line of sight), providing several additional minutes for decision-making.
- Dual alert mode — audible and visual signals for instant response, plus a graphical display on the screen in the form of a histogram. The strongest peak indicates an active signal in a specific frequency band.
- Video display — one of the model’s key features: the device allows displaying the actual image intercepted from the drone’s video signal on the screen, not just the presence of a signal.
Technical Features
Several key specifications of the device.
Frequency Coverage
“Chuyika 3.0” is a tri-band device covering three spectra:
- 900–1800 MHz
- 2870–4080 MHz
- 4860–6060 MHz
According to the manufacturer’s estimates, this covers up to 95% of the most common frequencies used by modern FPV drones with analog video transmission.
Compactness and Housing
The current weight of the device is approximately 650 g. The housing has IP54 protection, which increases resistance to dust and moisture in field conditions.
Battery Life
The battery provides up to 6 hours of continuous operation. Charging is done via standard USB Type-C.
User Interface
The histogram screen allows the user not only to learn about a threat, but also to understand which specific frequency band is being used, as well as to view the intercepted video from the drone’s camera — this increases a soldier’s situational awareness about the nature and direction of the threat.
Housing Color Options
Starting in 2026, “Chuyika 3.0” is available in several housing color variants to suit the needs of different services: tactical colors and camouflage for military use, and separate variants for the State Emergency Service and medical services.
Firmware Update Capability
Support for online updates via a mobile application enables users to quickly and conveniently keep the most current firmware version on their devices.
Codification
The device has a NATO codification number, which confirms its official identification within the defense procurement system and simplifies integration into allied logistics chains.
Use Cases
Infantry at the front line. A soldier carries the device with them, receiving warnings before the drone appears in their field of view — a chance to take cover, camouflage, or open fire in time.
Defensive positions. “Chuyika” can be placed in a dugout or fortification with an external antenna unit, while the screen remains in a safe location — this creates a “radar curtain” around the position.
On vehicles. The vehicle-mounted version helps crews stay prepared for aerial attacks while moving or stationary. In July 2026, “Chuyika” systems were installed on medical evacuation vehicles transferred to the Medical Forces Command of the Armed Forces of Ukraine and the National Guard of Ukraine.
Mobile UAV command posts. In February 2026, the “Come Back Alive” charitable foundation transferred 15 mobile unmanned aerial system command posts equipped with “Chuyika” portable detectors to the Defense Forces of Ukraine.
Price and Availability
The price of the detector is UAH 30,840 including VAT. Brigades can purchase the device directly from the manufacturer or through the Brave1 platform.
Additionally, it has become possible to obtain the “Chuyika 3.0” using E-Points — on the DELTA, DOT-Chain Defence, and Brave1 Market platforms under the state program “Army of Drones. Bonus,” which awards points to units for effective combat use of drones and robotic systems.
How “Chuyika 3.0” Differs from Previous and Subsequent Versions
Compared to “Chuyika 2.0” (a dual-band model at 1.2 and 5.8 GHz), “Chuyika 3.0” gained:
- an additional 3.3 GHz band;
- automatic scanning and expanded signal detection capabilities;
- an improved interface with a histogram and the ability to view intercepted video;
- the ability to update firmware online;
- better portability while maintaining high battery autonomy.
The product line continues to evolve: the company has already introduced “Chuyika 4.0” — a quad-band detector focused on real-time UAV signal detection and identification.
Conclusion
“Chuyika 3.0” remains a modern tactical-level tool that enhances the survivability of Ukrainian military personnel on the battlefield. Light, autonomous, and easy to use, it can provide additional response time before a drone appears in the field of view. Those few extra seconds or minutes of warning can still prove decisive for a soldier’s life.
- greater detection range;
- an improved interface with a histogram;
- the ability to update firmware online;
- expanded frequency ranges;
- better portability while maintaining high battery autonomy.
Conclusion
“Chuyika 3.0“ is a modern tactical-level tool that enhances the survivability of Ukrainian military personnel on the battlefield. Light, autonomous, and easy to use, it allows users to “hear” a drone before it is visible, and those few extra seconds or minutes can prove decisive.
