The Path to Real World Autonomy for Autonomous Surface Vehicles
ASV Global 2017
This paper presents a new autonomy architecture, developed and tested over the past two years which has taken a “dumb” remote-controlled platform and built it into a state-of-the-art Autonomous Surface Vehicle, able to navigate safely at high speeds in a COLREG aware manner, across some of the busiest waterways in the world. The architecture is made up of a hierarchy of decision making components sharing a common world model. These components consist of: a route planner, path planner and last response engine. Each element of the hierarchy is working to re-duce risk within decreasing time and space horizons, ultimately providing a minimum risk navigational solution. MAST and the collision avoidance system is now at the advanced prototype stage hence. Dstl and ASV welcome interest from other organisations who would like to explore and experiment with running their systems either onboard or otherwise in command.
Design, Build, Testing and Role of an ASV for Marine Security
ASV Global, 2013
The C-Stat developed by ASV Global is a station keeping vessel for applications where anchoring maybe difficult or the cost or practicalities of operating a manned vessel for continuous periods of time are prohibitive. For some applications, solutions using wave or wind powered station keeping platforms struggle to support the necessary payloads (mass, volume, electrical power) or positioning accuracy in strong currents. The aim of the C-Stat program is to produce a rugged, cost efficient and practical vessel capable of operating for weeks and months at low speeds whilst reliably holding position in high currents and powering payload equipment.
