SARA, Search & Rescue Aid, is a semi-autonomous tethered UAS designed to support vessels in the detection of people lost in the sea, especially during the hours of darkness

Unlimited flight time

The tethered configuration enables persistent flight operations making it ideal for prevention and management various emergency events.

semi-autonomous operations

The crew can operate the drone from a dedicated console inside the vessel’s command bridge.


SARA system aims to search, detect and georeference any source of heat in the darkness. SAR Operators can get thermal and optical video in real time, supporting rescuers’ action

POWERED BY high accuracy EGNSS

EGNSS technology provides feedback and accurate continuous measurement of the baseline from Drone to Hangar and optimization of its position.

System Concept

SARA is a semi-autonomous system composed by a tethered drone and its hangar, tightly coupled onboard the vessel through a strong kevlar cable used for power supply and data transmission.

Its main advantage, comparing to other drones available on market, is the possibility to deploy in a very short time a Virtual Pylon up to 100 meters above the vessel.

This means an instant aerial view around the vessel, useful to increase the situational awareness of operators in critical situation as Search and Rescue.

Moreover, it enables flight operations in poor visibility conditions by the means of satellite positioning and of visual and thermal infra-red payload.

The tethered solution clearly mitigates several risks of SAR operations, both ground-related and air-related, and not only improves the safety of people involved, but it is also useful for the risk assessments (SORA) required by new European drone regulations.
