ASV Global, together with TerraSond, has successful completed a hydrographic survey using the C-Worker 5 USV off the coast of Alaska, the company announced on 21 August.
The 10,649km survey was carried out alongside TerraSond's survey ship acting as the mother vessel. Fitted with a multibeam echosounder, the C-Worker 5 USV carried out 53% of the survey.
Throughout the operation, the C-Worker 5 was remotely monitored using ASV Global’s ASView control system from a station on the mother ship. ASView exported .dxf survey lines from the TerraSond survey planning system to autonomously execute an accurate survey with minimal human intervention.
The operation marks ASV Global and TerraSond’s fourth unmanned charting survey for the National Oceanic and Atmospheric Administration (NOAA).
Andrew Orthmann, charting programme manager, TerraSond, said: ‘The ASV C-Worker 5 was once again advantageous to our charting work for NOAA along a remote stretch of Aleutian Islands coastline.
‘It was productive in an offshore capacity, but also effective when working close to rugged, rocky shoreline with an abundance of uncharted navigational hazards. It allowed us to reduce risk to our personnel while still obtaining the seafloor data important to our client.’
As the dynamics of aerial combat rapidly evolve, Chinese scientists have engineered a sophisticated air separation drone model that can fragment into up to six drones, each capable of executing distinct battlefield roles and challenging the efficacy of current anti-drone defences such as the UK’s Dragonfire laser system.
Advancements in air defence technologies have begun to reshape aerial combat dynamics in the Middle East, as illustrated by recent events involving the Israeli Air Force and Hezbollah.
Both sides of the Russia-Ukraine war have been using UAS for effective low-cost attacks, as well as impactful web and social media footage. Thousands more have now been committed to Ukrainian forces.
The US Army has intentions to develop light, medium and heavy variants of the Robotic Combat Vehicle (RCV) as part of the branche’s Next Generation Combat Vehicle family.
DroneSentry-X, a cross-vehicle compatible, automated 360° C-UAS detect and defeat device, can offer 360° awareness and protection using integrated sensors. According to its manufacturer, it is suitable for mobile operations, on-site surveillance and on-the-move missions.
Funded by the country’s former president, the new C-UAS systems will be sent to the frontline where they have already been tested against Russian invading forces.
