SYSTEM OVERVIEW

The Double Eagle Sarov can operate as an AUV, with an onboard inertial navigation system allowing the vehicle to navigate over great distances and depths.

Alternatively the Sarov can be operated via a several kilometre long fibre optical tether or a tether providing both power and real time communication for the vehicle. For MCM operations the Double Eagle Sarov can be used for detection, classification, identification and disposal.

The Dock and Release Mechanism on the vehicle gives it the capability to release and redock with the tether under water, avoiding retrieval of the vehicle for battery charging and up/down loading of data.

THE SAROV SYSTEM

The SAROV System is a complete system, including Integrated Logistic Support package components, configured to achieve cost-effective operation for each kind of mission.

The System consists of:

  • The SAROV vehicle
  • Mission Planning & Analysis Unit
  • Battery Recharging System
  • ILS package
     

An onboard charger is used to recharge the battery while dumping data and preparing for a new mission. Whilst the battery is being recharged it is still possible to operate the vehicle in ROV mode.


CONTAINER SYSTEM

To meet customer requirements for optimized flexibility, the SAROV and necessary auxiliary equipment are put into a standard container that can be placed on and operated from any location or craft of opportunity (COOP), e.g. a multi-role vessel or a quay.
