Euronaval Show News – Teeth of the Hydra

CerbAir’s Hydra CUAV system has recently undergone evaluations with the French Navy as a potential mechanism to protect ships against micro and mini UAVs.

This year’s Euronaval exhibition is taking place online. The event, which normally happens in Paris, is being presented digitally because of the ongoing Covid-19 pandemic.

During the exhibition CERBAIR revealed that the company concluded experiments with the Marine Nationale (French Navy) this June to demonstrate that its Counter-Uninhabited Aerial Vehicles (CUAV) systems protect naval vessels against micro and mini drones. Such aircraft can be difficult to detect because of their small size, yet they can pose a danger by collecting imagery intelligence and even be used to deliver explosives.

At the heart of CerbAir’s CUAV approach is the detection of the Radio Frequency (RF) signals connecting a UAV and its Ground Control Station (GCS) to one another. UAVs typically use frequencies of 2.4 gigahertz/GHz and 5.8GHz to connect the aircraft to the GCS. The aircraft will also receive GNSS (Global Navigation Satellite Signal) transmissions across wavebands of 1.1GHz to 1.6GHz and use RF to share imagery via the aircraft’s data links.


The company’s Hydra electronic support measure will detect the UAV’s RF signals and pinpoint its location by using a telescopic mast. This information is displayed on a laptop or a computer screen.

Hydra can be used in fixed, mobile, portable and embarked configurations. The aircraft is then engaged using an electronic countermeasure to jam these RF links. During the French Navy tests KEAS supplied the jammer to attack the RF links.
