L3Harris - ASV C-Cat 3

Robust, shallow water ASV

The C-Cat 3 is a robust and easy to use Autonomous Surface Vehicle (ASV) ideally suited to shallow water operations in inshore and coastal environments.

The vehicle has a manually deployable keel and is capable of housing multiple standard sensors such as an ultra-short baseline (USBL) and a multibeam echosounder (MBES).

Its shallow draft and manoeuvrability make the C-Cat 3 ideal for operating in areas otherwise inaccessible to manned vessels.

Description

The C-Cat 3 is a robust and easy to use Autonomous Surface Vehicle (ASV) ideally suited to shallow water operations in inshore and coastal environments. 

The vehicle has a manually deployable keel and is capable of housing multiple standard sensors such as an ultra-short baseline (USBL) and a multibeam echosounder (MBES). 

Its shallow draft and manoeuvrability make the C-Cat 3 ideal for operating in areas otherwise inaccessible to manned vessels. As well as operating as a standalone survey platform, the C-Cat 3 can be a complementary asset to existing survey methods and used alongside a manned vessel.

The C-Cat 3 is also well-suited to Unmanned Underwater Vehicle (UUV) locating and tracking in applications such as pipeline survey.

The C-Cat 3 can carry out a full day of standard operations from a single battery charge. For more substantial operations, the batteries can be quickly changed without powering down the system.

The vehicle is quick to mobilise and easily launched via a slipway or overhead lift.

C-Cat 3 vehicles have been deployed in operations all over the world for tasks including hydrographic survey, above-water mapping, UUV locating and tracking, and acoustic communication.

The C-Cat 3 has proved itself a safe, reliable and robust vehicle for operations in coastal environments.

The C-Cat 3 operates using the ASView autonomous control system. It can be controlled manually or to follow pre-programmed routes that can be updated at any point through an easy to use PC based graphical user interface.

Control modes include waypoint and line following, heading and track hold, station keeping and remote control.

ASView features standard S57 navigational charts with the ability to import files such as geotiff and .dxf survey lines.

The vehicle comes with a standard communications and situational awareness system giving it the ability to outside the operator’s direct line of sight.

The optional enhanced communications and situational awareness suite gives the C-Cat 3 an extended range of operation and the ability to operate in situations with reduced visibility.

The C-Cat 3 has an emergency stop safety function as well as an AIS based last response system which disengages the propulsion system.
