Our DAU & SJ C-UAS technology is the foundation upon which all ASDT stationary systems, both detection and neutralisation, are developed. 

It is a versatile, modular, flexible and easy to implement technology that can be installed on masts, ceilings or towers. Additionally, the system features a IP66 protection, making it weather resistant. All of this converts our systems into the perfect platforms for securing large areas or critical infrastructures such as airports, prisons, nuclear plants, oil refineries, government buildings or even urban centres. 


Due to the integration with the SENDES Ecosystem, our stationary detection systems (known as SENDES DAU) can share real-time telemetry data of all detected drone flights. This information is then transmitted to the SENDES Core (the intelligence of the ecosystem), where it is handled and processed to then be displayed in the SENDES Gate (the interface of the ecosystem). 

Finally, and always following the defined parameters in the SENDES Core, our stationary neutralisation systems (known as SENDES SJ) can be activated either remotely or automatically. 

Furthermore, the DAU & SJ technology can operate in conjunction with detection, identification & tracking and / or neutralisation systems from third-party manufacturers, as well as with other C-UAS technologies. 


The DAU technology features the functionality to detect drones that operate either with DJI technology (i.e. WiFi, Lightbridge or OcuSync) or with Remote ID technology (i.e. Bluetooth 4, Bluetooth 5, WiFi Beacon or WiFi Aware), designed following the European and North American drone regulations, up to a distance of 10km with the SENDES DAU-K10 system.

Thanks to its modular design, the DAU technology allows the integration of other detection modules, to detect drones from manufacturers such as Yuneec or Parrot, or even to detect and locate transmissions of technologies such as ADS-B or WiFi. The data gathered by the DAU technology comprises, among others, the following fields: drone manufacturer and model, flight controller serial number, GNSS coordinates of the drone, pilot and take-off point, as well as the speed and height of the drone. 


The SJ technology comes in two systems with different neutralisation methods: either a) 90º directional neutralisation in all geographical directions (SENDES SJ-90), or b) omnidirectional neutralisation (SENDES SJ-360).  

Either way, both systems are capable of providing a “360 security”; able to neutralise swarms of drones flying both simultaneously and from multiple directions. Additionally, for the SENDES SJ-90, possible electromagnetic interferences with electronic devices are minimised, or even eliminated, in the areas where there is no drone threat.

Both neutralisation systems can inhibit the control transmission between the drone and the remote controller (ISM bands: 2.4 GHz and 5.8 GHz), the GNSS satellite signal reception (GPS L1, GLONASS G1 or Galileo E1: 1.6 GHz) or both, simultaneously. In addition to these three frequencies, the SENDES-SJ90 features the possibility to integrate up to four neutralisation channels and the SENDES-SJ360 up to five. These extra frequencies may be any band between 100 MHz and 6 GHz.
