Disposable fiber-optic spools for hybrid Aerial and Underwater drones
The RBOB-HAUV for amphibious drones and hybrid airborne and underwater applications is the latest addition to the range of airborne (UAV), land-based (UGV) and underwater (UUV) spools already offered by SEDI-ATI.
Drawing on its experience in the field of optical wire links on aerial and underwater UAVs, SEDI-ATI is offering a singleuse fiber-optic spool for amphibious UAVs: RBOB-HAUV. Ultra-compact and lightweight, it is mounted directly on the drone. It is designed for high-speed missions of up to 10 km, both in the air and deep water! It has been tested at 150 km/h in the air and 20 knots underwater.
It is particularly well suited to guiding an amphibious drone, and to transmitting huge data streams in real-time from on-board cameras and high-resolution sensors. Moreover, it's an EMI-insensitive solution, immune to Hertzian jamming. As a result, manoeuvres such as diving, getting out of the water, circling or even around obstacles are not a problem. It will be possible to access steep or hard-to-reach places. The fiber-optic cable is never a ‘leash’ on the drone and ensures permanent, real-time communication between the craft and the control station.
The spool is single use, so all you have to do is cut fiber at the end of the mission. There's no need to make the same journey back because the optical fiber is never a leash on the drone. Moreover, the fiber can be easily reconnected in the field using a simple connector kit.
The technical characteristics are the same as for the submarine reel: length from 500 meters to 10 kilometers, singlemode fiber 1310-1550 nm, ST connector, wide bandwidth for video and control transmissions.
Impact Subsea Launches the ISP360 Profiling Sonar together with IS3 Acoustic Signalling Standard
