IMSI Catcher for DJI Matrice 350 RTK drones: what it is, how it works, and why it revolutionizes aerial surveillance
The world of security, civil defense, and emergency operations is experiencing an unprecedented technological revolution. Enterprise drones, such as the DJI Matrice 350 RTK, are no longer simple aerial platforms: with the right payloads, they become strategic intelligence and rescue tools.
Among the most innovative technologies are IMSI Catchers for drones, advanced devices capable of intercepting and locating cellular signals. These systems transform a UAV into a mobile aerial surveillance center, opening up operational scenarios that were unthinkable just a few years ago.
But what is an IMSI catcher? How does it work? And most importantly: what are the real benefits of using it on a drone like the DJI Matrice 350 RTK?
What is an IMSI Catcher and how it works
An IMSI Catcher (International Mobile Subscriber Identity catcher) is a device that simulates a cellular base station. Its job is to induce phones in a defined area to connect so that they can be identified and located.
In simple words:
Docking (Handshake) -the phones detect the strongest signal (that of the catcher) and connect.
Identification-each device reveals its own IMSI code, that is, the unique SIM identifier.
Localization – with drone movements or signal triangulation, the location of the phone can be estimated accurately.
In more advanced models, it is possible to force less secure protocols (e.g., 2G) to intercept communications, but these practices are subject to strict legal restrictions.

Why Mount an IMSI Catcher on a DJI Matrice Drone
Integrating this technology into an enterprise drone such as the DJI Matrice 350 RTK means multiplying its operational capabilities:
Rapid coverage of large areas-square kilometers within minutes, without physical obstacles.
Discreet surveillance-high altitude operations, often invisible and inaudible from the ground.
Access to hazardous areas -monitoring in areas of landslides, collapses or attacks without risk to personnel.
Superior signal quality-the elevated position reduces interference and increases accuracy.
Compared with a terrestrial system, an IMSI catcher on drone offers incomparable mobility, speed and safety.
Strategic Applications of IMSI Catchers
The scenarios in which this technology makes a difference are many and often vital:

Search and rescue (SAR)
Earthquakes and collapse: detection of active phones under rubble.
Avalanches and mountains: locating missing persons in inaccessible or snowy areas.
Floods: mapping of submerged areas to identify trapped people.

Law enforcement and public safety
Anti-crime operations: tracking suspects and disposable phones.
Major events: monitoring crowds at concerts, stadiums, events.
Border control: detection of illicit trafficking, smuggling and illegal immigration.

Civil defense and critical infrastructure
Surveillance of dams, power plants, industrial plants.
Prevention of sabotage and threats to national security.
IMSI Catcher for DJI Matrice 350 RTK: the solutions available
DroneBase offers two IMSI Catcher models designed to plug-and-play integration with the DJI Enterprise ecosystem. Both use advanced XP²-Locator software and offer operational range up to 20 km (FCC).
IMSI Catcher 2 Channels (IMSI-X02)
The 2-channel model represents the perfect balance between performance and agility. Weighing only 0.9 kg, it has minimal impact on the drone’s range, providing extended flight times (up to 42 minutes). It is the ideal solution for rapid search operations and targeted surveillance.
- Channels: 2 simultaneous SDR channels
- Weight: 0.9 kg
- Detection Speed: Up to 400 terminals per minute
- Autonomy M350: Approximately 42 minutes
- Ideal for: Rescue teams, patrol, police operations requiring maximum mobility and extended flight time.
IMSI Catcher 4 Channels (IMSI-X04)
The 4-channel model is the cutting edge of aerial surveillance. Designed for the most demanding operations, it offers double the detection capability and superior power, making it the ultimate tool for signal-dense scenarios, such as large events or complex counter-terrorism operations.
- Channels: 4 simultaneous SDR channels with higher power
- Weight: 2.5 kg
- Detection Speed: Up to 800 terminals per minute
- Autonomy M350: Approximately 26 minutes
- Ideal for: Special units, military intelligence, metropolitan area security management and critical infrastructure where maximum data collection capability is a priority.
Legal aspects and regulations
IMSI catchers are very high-impact privacy tools. Therefore:
Legal use: reserved for Law Enforcement and Intelligence Services, subject to judicial authorization.
Ban on individuals: companies, investigators and citizens cannot purchase or use them.
Legislation in Italy and Europe: likened to wiretapping, subject to strict regulatory control.
👉 In summary: these are technologies available only to authorized government agencies.
Frequently Asked Questions (FAQ)
What is an IMSI catcher?
It is a device that simulates a cellular base station to identify and locate phones in a defined area.
How does it work on a DJI Matrice 350 RTK drone?
The drone flies over the area and collects IMSI codes from phones, allowing it to locate people or monitor suspicious activity.
Why is it useful in search and rescue?
It can locate missing people by detecting their phones even without traditional network coverage.
How much does an IMSI catcher for enterprise drones cost?
The price varies depending on the model (2CH or 4CH) and functionality required, but remains affordable only to government agencies.
Is it legal for private individuals?
No, use is prohibited for citizens and businesses. Only law enforcement agencies can legally operate these tools.
