Autonomous Underwater Vehicle, REMUS 6000
REMUS 6000 - the deepest member of Hydroid's growing family of Autonomous Underwater Vehicles - AUVs!
REMUS 6000 features
- LITTORAL TO DEEP OPERATIONS - The REMUS 6000 has been designed to enable operations to water depths as great as 6000 meters. The versatile design also allows long mission durations in shallow littoral areas.
- CUSTOM DESIGN - The REMUS 6000 can be configured to include a wide range of customer specified sensors. The sensor suite can be reconfigurable and enables the REMUS 6000 to be configured to meet specific, and varied, mission requirements.
- EASE OF OPERATION - The REMUS 6000 incorporates the same proven Vehicle Interface Program (VIP) used in the complete family of REMUS vehicles. The highly refined VIP makes vehicle maintenance, checkout, mission planning, and data analysis fast and easy. Windows operation, quick look indicators, quality control checks, and a sophisticated data export capability all add to the user friendly nature of this software package.
- LAUNCH AND RECOVERY SYSTEM (LARS) - The REMUS 6000 Launch and Recovery System is designed to function off the stern of a ship and can be set up for shipboard operations within a few hours. the LARS is a roll on/roll off system and can be installed easily on ships of opportunity. Launch and Recovery can also function off the stern and side of a ship.
- PROVEN REMUS TECHNOLOGY - The REMUS 6000 is based on the same leading edge technology that has brought the REMUS 100 to the forefront of autonomous operations.

Auxiliary Support Equipment / Vehicle Safety Features
All HYDROID AUVs have core systems designed to monitor the status and operation of essential components. Health monitoring includes batteries, motors, sensors and communications as well as conditions such as depth or water ingress. If an abnormality is detected, then an alarm is raised. During supervised missions this will be transmitted to the operator enabling them to decide if the vehicle should return from its mission. When the vehicle is operating autonomously, the response to an alarm is determined by the preselected response listed in the mission plan. This could include an emergency abort to preserve vehicle security.
Communication and Tracking
Operators can monitor the AUV's progress and status via an acoustic link. This also enables amendments to the mission plan to be sent to the vehicle along with position updates if required. The HiPAP (KONGSBERG acoustic underwater positioning and navigation system) or Ranger positioning systems provide acoustic aiding to the on-board IMU (Inertial Measurement Unit) and DVL (Doppler Velocity Log) equipment to make the real-time position solution as accurate as possible. Some HYDROID AUVs also transmit real-time side-scan and bathymetry data back to the operator acoustically. This data is displayed on the payload computer screen to give the operations team confidence that the mission is progressing as planned and there are no gaps in the data. When the AUVs are on the surface, they can communicate via Wi-Fi or radio with the operator. They are also equipped with GPS receivers to update the IMU position with the most accurate information available.
To assist with emergency localisation and recovery operations, the AUVs can be equipped with emergency radio beacons, strobe lights and satellite communications. In the event of an emergency ascent, the position and status of the vehicle can be sent via the Iridium network to the operators and home base simplifying post-emergency localisation. If two-way satellite communication is enabled, a revised mission plan can be sent to the vehicle from anywhere in the world.
