“Below the Starlink is a suite of fixed cameras from Garmin, facing all different directions and mounted on a set of three-way, yard-armed spreader bars. Down from that is a Redvision camera for providing both daytime CCTV and also a spotlight functionality, both of which will help a lot with self-surveillance, checking for issues on our own vessel, even for seemingly trivial things like accidentally dragging a lobster pot behind us, as those can and have downed USVs crossing oceans before.” Those cameras bring the added benefit of amassing training data, with copious real-world, in-context video and imagery for training future AI systems to be used on Pioneer-class H-USVs, and others. Three antennas sit about the Garmin cameras. One provides a Class A AIS link and the other two are VHF antennas: one connects to a Digital Selective Calling radio, and the other to a Channel 16 Dual Watch radio (both being established radio protocols for distress and safety messages at sea). “Moving down, we have a Simrad radar – a HALO24, specifically – and below again is a second three-way spreader bar, which mounts a 4G antenna, a wi-fi antenna and an Airmar 200WX weather station,” Mulcahy says. “As well as giving us our on-location weather data, the 200WX integrates a GPS radio, as well as a three-axis gyroscope and accelerometer, thereby acting as a secondary source of heading, pitch and roll information.” Slightly inboard of the 200WX is a small UHF antenna for LOS operations, and underneath that spreader bar is an array of localisation devices. While ACUA Ocean tries to stay agnostic about navigation suppliers (as almost all maritime customers will have their own specific, individual attachments to one navigation supplier over another), the USV Pioneer is carrying a Hemisphere Vector V500 GNSS Smart Antenna, a magnetic heading compass and a NavtechGPS system, at least for its initial sea trials. Level 3 autonomy To conform with safety regulations, the Pioneer-Class will initially be operated at Degree Three of the International Maritime Organisation’s Maritime Safety Committee’s regulatory framework for maritime autonomous surface ships (MASS). This means it will be able to handle itself and most onboard safetycritical systems in most instances, with an operator in-the-loop to monitor its missions at all times and step in to take control where necessary, but under virtually no circumstances will personnel be present onboard the MASS. “That’s geared our onboard control architecture, as IMO Degree Three still requires considerable computer hardware, but, fortunately, the Robosys control software we’re using comes with an OEM-recommended compute unit,” Mulcahy says.
