Countering drones early on

ARDRONIS counter-drone solutions

Detecting, localizing and disrupting RC drones

The proliferation of malicious and non-cooperative drones is an ever-increasing threat to aviation and sensitive site security. Whether it be disruption of critical national infrastructure at home or risk of life to forward-deployed personnel abroad, civil and government organizations and agencies; all of them require affordable and reliable counter-drone solutions. Protective measures can only be taken after a threat is detected. To effectively counter the threat, early warning is necessary – every second counts.

ARDRONIS is a family of counter-drone solutions from Rohde & Schwarz. The system-of-systems approach provides customers with the ability to detect-identify-locate-track-verify-counter malicious and non-cooperative threats in line with their unique, end user requirements.

When ARDRONIS detects commercial drone activity, it automatically classifies the type of drone signal, determines the direction of the drone and its pilot, and disrupts the radio control link to prevent the drone from reaching its target.

The majority of commercial remote controlled drones are controlled (uplink) via frequency hopping spread spectrum (FHSS), a modern frequency agile waveform. Another major family of drones is controlled (uplink) via WLAN. Signals transmitted from the drones (downlink) are typically FHSS, wideband or WLAN signals.

    Features & benefits

    Detection and identification

    ARDRONIS is capable of detecting and identifying the signals of commercially-available drones and remote-controls. By default, FHSS-controlled drones and with the ADRONIS WiFi-option also WiFi-controlled ones.

    Direction finding

    The advanced ARDRONIS solutions are capable of locating FHSS-controlled drones and their operator. The direction information gives security personnel a real tactical advantage by enabling a fast and effective response to the drone and the pilot.

    Active countermeasures

    With a range of different functions like jamming, disruption of WiFi control links or the geolocation calculation ARDRONIS enables an appropriate response to single or multiple threats.

    Early warning

    Early warning is the key to counter any threat. ARDRONIS can detect RC activity even before drones take off. Early warning alone often ensures an effective response, including pilot interception.

    Flexible operating environments

    Dependent on the requirements of the environment the ARDRONIS solutions and options can be selected and combined in many ways to guarantee the highest possible protection. ARDRONIS can be integrated on permanent structures including airports, borders or prisons but is also rapidly deployable as a semi-mobile solution for shorter duration operations (e.g. VIP, event and convoy protection).

    Situational awareness

    Continuous reporting of drone activity on all relevant frequencies within a large coverage area provides situational awareness.

    Easy operation

    ARDRONIS Detect can be operated with minimal training. When a signal is classified as a threat, the operator is immediately alerted via the user interface or individually set alarms.


    Future-ready means, the solution and signal database are frequently updated, with capacity to support software upgrades and options for add-ons.

    Open interface

    An open interface enables integration into multivendor and multisensor solutions, making ARDRONIS particularly attractive to integrators. For the interconnection between remote sensors, ARDRONIS offers 3G and 4G connectivity.
