Oshen

3,000 days at sea! This cool video shows C-Star missions from February 2024 to October 2026. It's great to see how far we have come but wouldn't be possible without the amazing team behind it and all our brilliant partners. There's plenty more where that came from. Next stop: 10,000 days and even more oceans to explore!

An update on the C-Stars in Hurricane Isaias ⛈️

Ocean, weather and space data rarely line up. What happens when they do? That’s the question Matt Bristow, Founder & Chief Scientist at MISTT, will tackle at the next Weather, Ocean & Climate Evening here at Oshen HQ. His talk, One Address for Every Measurement, looks at what changes when observations from buoys, uncrewed vessels, weather models and satellites all sit on a single shared grid. Furthermore, what that unlocks for forecasting, research and operations. We’re looking forward to hearing Matt’s take. 📅 Thursday 15 October, 18:00–19:30 BST 📍 Oshen HQ, Turnchapel Wharf, Plymouth 🔗 Link in the comments #OceanData #Metocean #ClimateScience #Plymouth #MarineTechnology

Two Oshen C-Stars have intercepted Hurricane Isaias, with PD20 passing the closest. We'll be sharing more of the data and results early next week - keep an eye out for updates.

A quieter Atlantic Hurricane season this year due to a very strong El Niño, with the first hurricane occurring this week, making it the latest date a hurricane has formed since satellites were available to track them from space. With the UK continuing to invest in new observations it was great to see Plymouth based Oshen moving their C star autonomous marine surface vessels into position to provide crucial data to track the storm before it moved overland. British technology supporting weather intelligence on a global scale! Great for Plymouth, great for Oshen and great for the UK economy. https://lnkd.in/eYQjBc9M

Sparse observations can still make a huge impact. Oshen have recently integrated elements of the Met Office and University of Exeter developed MaLCOM (machine learning for low-cost offshore modelling) framework into their mission planner dashboard. This enables real-time regional extrapolation from point-based measurements collected by a constellation of C-Stars. Last summer, we demonstrated observations from moving platforms can be ingested into MaLCOM to construct a wave forecast across the whole South West UK with sparse observations. Currently, we are running live sea surface temperature spatial reconstruction using C-Star observations. This is also in the process of validation and verification. This is Phase One. The next step is turning reconstruction into forecast and an adaptive sampling loop so that a fleet autonomously repositions itself based on where the forecast is least certain. #modelling #forecasting #marinedata

REPMUS 2026: what we learned using C-Stars alongside NATO navies This September, 6 C-Stars joined REPMUS (the largest annual military exercise for maritime robotics) off the coast of Portugal. It was the first time our acoustic picket line was tested against real targets and here’s our key takeaways: Teamwork is everything Teams on shift around the clock and engineers on the dock made sure the fleet kept running as one. We are incredibly grateful for the dedication from the teams involved. Interoperability takes work up front Getting our data into the wider operating picture was some of the most demanding but important software work we did before the exercise. A sensor that can't share what it hears isn't much use to anyone. Nothing beats time with end users The real value of REPMUS was working directly with the operators who would use C-Stars. They showed us how we fit into their picture, and we changed things on the spot as a result. Reliability is non-negotiable When dozens of autonomous systems are operating together, a platform that needs constant attention is a problem. Thank you to the REPMUS organisers and everyone who worked with us. #REPMUS2026 #MaritimeAutonomy #USV #UncrewedSystems

Oshen plans to build on its anti-submarine warfare (ASW) experiments at REPMUS 26 with further trials in the U.S. this month and the North Atlantic next year. In Portugal last month a six-boat C-Star constellation featuring acoustic sensors — omnidirectional hydrophones on a 3m tail — were deployed against live targets for the first time. The 1.2m C-Star uncrewed surface vessels were deployed both by hand from rhibs and also off the back of French Navy support ship Seine. The drones were distributed laterally across a designated area to create an acoustic picket-line tasked with detecting NATO submarines using integrated acoustic sensors from Systems Engineering & Assessment Ltd (SEA). #defence #Oshen #REPMUS26 #ASW #CStar #USV #uncrewed #autonomy #drones #SEA #NATO #NavyLeaders Read more here: 🔗 https://lnkd.in/e-RDJ5Qj
