Recorded drone activity, Spain 2022
46,000+
Spanish ASDT SENDES systems recorded this number of drone operations in monitored airspace in a single year. It is an indicator of the actual scale of unauthorized flights over sensitive areas.
Proven in real-world use: ASDT systems protect airports, correctional facilities, nuclear power plants, LaLiga football stadiums and the Sagrada Família in Barcelona, among other sites.
Why this matters now
The airspace above your site is no longer a no-man’s-land.
Commercial drones are affordable, quiet and readily available. What began as a recreational device becomes a risk at sensitive sites: industrial espionage over company premises, disruption of air traffic, unauthorized recordings during events or the smuggling of objects into protected areas.
Security authorities and critical infrastructure operators are already responding. In Spain, C-UAS systems now operate 24/7 at airports and industrial facilities. They are no longer an exception, but a standard component of modern security concepts.
✈️ Airports & airspace Disruptions caused by unauthorized flights + View details
A single unauthorized drone sighting near a runway can restrict air traffic for hours, resulting in additional costs for airlines, operators and passengers. Passive RF detection identifies these flights before they enter critical airspace and provides air traffic control with a reliable operational picture instead of an assumption.
🏟️ Stadiums & major events Crowds as a sensitive protected area + View details
At events with high concentrations of people, the airspace above the crowd is often the least controlled area. Mobile detection units can be deployed at short notice and add a third dimension to conventional perimeter security without disrupting ongoing operations.
🏭 Companies & production Risk to trade secrets and processes + View details
Industrial sites with confidential production or prototype development are usually well protected at ground level, but the airspace above them often is not. A single unnoticed overflight can be enough to expose production processes or unreleased products. Continuous RF detection closes this security gap.
Why this matters now
The airspace above your site is no longer a no-man’s-land.
Commercial drones are affordable, quiet and readily available. At sensitive sites, they become a risk ranging from industrial espionage over company premises to disruption of air traffic.

From detection to decision
How a radio signal becomes an actionable operational picture.
01 Detection · 02 Classification · 03 Localization · 04 Assessment

Step 01
Passively detect supported drone signals
The system analyzes the RF environment for known, supported communication patterns between the drone and its controller. In detection mode, the system does not transmit a signal of its own.
The first step is not counteraction, but early awareness of flight activity

Step 02
Classify the available signal information
Detected signal patterns can support the identification of the manufacturer and model. The scope and level of detail depend on the specific drone system and its transmission standard.
Technical classification supports the assessment, but does not replace an evaluation of the operational context

Step 03
Locate the position and flight path
Detected activity appears live on the map in SENDES Gate, the central user interface for both system variants. Depending on the available signal data, the position, flight direction and takeoff point may be displayed.
The operational picture helps distinguish between an approach, an overflight and recurring activity

Step 04
Assess activity and respond
Warning zones, flight paths and event histories support your security team during the assessment. The stationary system variant can optionally be expanded with a neutralization module. The appropriate response is always defined by your security process.
The system provides the information required for assessment. The decision remains with you.
Transparent technical assessment
The information available depends on the drone model, transmission standard, site, RF environment and selected system configuration.

What we clarify openly before preparing a quote
The right system starts with the right expectations.
These limitations do not count against SENDES. They determine whether the system can be used effectively at your site.
01 Range
Terrain, buildings, the RF environment and the mounting position affect the actual range.
02 RF protocols
Not every autonomous, modified or unknown aircraft transmits a supported signal.
03 Detection
Passive detection provides an operational picture. It does not automatically neutralize an aircraft.
04 Configuration
A stadium, an industrial site and a logistics center require different security concepts.
Our promise: If the site, RF environment or risk profile speaks against the selected solution, ProFlyCenter will tell you before you buy.
