ASView offers operators a range of control modes, each suited to different types of mission and mission stages. This gives the operator the flexibility to execute basic remote control right up to fully autonomous mission planning utilising a single user interface.
The control modes comprise:
Direct remote control via ASView-Helm.
ASV-Helm enables operators to directly control the ASV for precision manoeuvres such as launch and recovery.
Assisted remote control; heading, course over ground and speed hold.
Assisted remote control provides operators with a simple interface for less complex mission stages such as transit.
Mission plan via ASView-Bridge UI consisting of lines, orbits and/or station keeping waypoints.
Mission plans in ASView enable the operator to plan a range of complex missions in detail, ideally suited for use during tasks such as survey operations and construction support.
Autonomous aided control. The next step in ASView capability due in 2017. Intelligent mission plan changes and on board navigational decision making to avoid collision and achieve mission goals. Operator overrides only if required.
Back seat driver interfaces with third party or open source systems including MOOS and ROS allowing research customers to develop their own autonomy applications without needing to concern themselves with safety critical vessel controls
ASView is able to control and monitor power generation and propulsion engines, motors and drives. The vessels electrical system, data buses and safety systems are all controlled and monitored with visual displays provided on the ASView-Bridge operator interface.
ASView can be easily integrated with existing craft using a number of standard marine interfaces such as NMEA 0183 and 2000, CAN bus engine controls and simple electrical interfaces.
ASView provides situational awareness to the operator through the use of a wide range of navigation sensors. Interfaces are available for GPS receivers, gyro stabilised and satellite compasses, inertial navigation systems, marine radar systems, AIS, electro optical and thermal cameras and depth sounders.
The ASView-Bridge user interface has clear navigational data displays, full S57 electronic navigation charts with AIS and radar overlay, dedicated radar display and fixed and stabilised pan, tilt and zoom camera displays.
When conducting any unmanned vessel operations, safety is of paramount importance. The ability to safely halt the ASV or recover it are critical. ASView includes the following safety features:
ASView is compatible with large range of commercially available line of sight and satellite communications systems. Line of sight communications include narrow and wide band links in UHF, L or S bands. Satellite communications can be conducted via Iridium, Inmarsat or V-Sat systems.
ASView can be interfaced with a variety of above and below the water payloads in order to deploy, operate and extract data in realtime. Various options are available providing minimal through to extensive payload data interaction for the remote operator.
