Autonomous capabilities With the addition of batteries the SAROV will have the possibility to go on autonomous remote operations. These operations can either be under autopilot control with local positioning using doppler and an INS or manually supervised, controlled either by radio or acoustic communication. When controlled by a tether either a power/optical tether or a fibre only tether can be used. Using fibre-optics long range with very high bandwidth communication can be achieved. The SAROV will be equipped with an underwater dockable optical/power connector. This connector can be released and redocked underwater. Using connectors developed for deep water ROV mating in the offshore industry the SAROV is able to recapture the tether, use it as a guide and pull the connector into a mating position, and then reconnect. This redocking capability allows the SAROV to be operated both from conventional ships but also from simple drones that are fitted with a power supply and a tether management system. This allows the SAROV to be operated at long ranges from its parent ship. When the SAROV is in the docked position the batteries are recharged. The SAROV can thus be used as a conventional tethered ROV for MDV or PVDS applications while the batteries are recharged. The redocking/recharging capability (i.e. air-to-air refuelling) gives the SAROV virtually unlimited endurance.
Proven Design The PVDS/ROV-S system has been developed using a modular design and a step-by-step process with reliability and proven components as a main focus. In addition due to the nature of the mine-hunting mission for which it was designed (high speed and long range) a lot of effort has been put into developing an efficient hydrodynamic shape and propulsion. Therefore as much as 90 % of the existing PVDS/ROV-S design can be reused in the SAROV platform. The autopilot already exists; the existing autopilot that is used today for the Saab PVDS/ROV-S systems is used also in the SAROV. The battery system is made using well-known technology that has been used for both the ROVs and AUVs produced by Saab. The main difference is that now the charger is built into the ROV, utilizing the power system used in the existing tethered ROVs. Communication systems, both acoustic and radio, mission planning system, and W-LAN has been extensively tested and evaluated in the Saab AUV 62 program. Inertial navigation combined with Dopler Velosity Log and Acoustic Positioning System is off the shelf technology that has been tried in Saab ROVs and AUVs. The docking system is a new combination of existing technology. It is based on existing connectors and Saab is currently (spring 05) in progress with development of this system. This means that the SAROV system benefits from the development and operational experience of all Saab ROVs, providing better reliability and support than specialized vehicles produced in small quantities. Autopilot Already exists. ROV is piloted automatically and the ship simply follows in the track of the ROV. Battery system Well known technology that has been used for both the ROVs and AUVs produced by SBUS. The news is that the charger is built into the ROV, utilizing the power system used in the existing tethered ROVs. Communication Acoustic W-LAN and Radio communication. This is also well known technology that has been used in SBUS ROVs and AUVs. Navigation Inertial navigation combined with doppler and APS. Existing off the shelf technology that has been tried in SBUS ROVs and AUVs.
Reconfiguration The SAROV will be reconfigurable for different applications. The same platform can be adapted to mine-hunting sonars, mine disposal charges or to carry other sensors or tools (cameras, chemical sensors, salvage tools etc.). This will be done using the same interfaces that have been developed and proven for the existing ROVs. This means that the same platform can be used for mine hunting, survey, surveillance, mine disposal and general intervention. One reconfigurable platform MDV, inspection, intervention PVDS, surveillance and survey Autonomous Programmed operation Radio/Acoustic control Long fiber-optic tether operations Underwater dockable Allows redocking to drone for long range remote operation Re-charge of the vehicle battery during simultaneous tethered operation. “Air to air refueling” Virtually unlimited endurance
