Remotely Operated Towed Vehicles - ROTVs
We have delivered several towed vehicles to date. Each project was a collaborative effort with the operator to provide a platform made to carry their specific payload.
Passive sleds are best suited for deeper applications, and when depth of operation is controlled by how much cable is paid in and out.
Active sleds are fitted with dive wings and/or elevons that the operator can control from the ship. They are used when the applications call for frequent undulations or altitude keeping, etc.
USGS Bio-acoustic Sled
If your applications require covering large areas and gathering big data, a remotely operated towed vehicle is a great solution.
Our design philosophy:
Adjustable ballast and buoyancy
Adjustable control surfaces to minimize pitch and roll
Protective elements that can be quickly replaced in case of failure in the field
Large U-bolts and/or anchoring points for tag-lines
Smooth under-carriage to slide the sled onto the deck and ease recovery
Tow Fish and Smaller Sleds
Our smaller platforms have a great track record and can be fitted with affordable navigation system (see our NavBox) and/or a ROV-style twisted-wire telemetry pod.
Our architecture of choice:
A Fiber-optic tether allowing for very high data rate (from 2.5Gbps and up).
Mux cards that provide each sensor their own independent channel
Add Relays, A/D Cards, Motors Drivers
and Power bricks for automation and control.
Data collected and displayed in real-time onboard the support-ship using a versatile, highly customizable user-interface
