Last week Iain travelled to Portugal to join up with the Royal Navy to deploy their ecoSUBm5-Power+ Scout AUV, featuring a brand new Nortek Nucleus DVL-1000, Power+ module for extended endurance and 1200kHz side scan sonar system from Marine Sonic Technology. The AUV was also equipped with sensors for conductivity, temperature and fluorometer for Chlorophyll-a, a nano-modem for underwater communications and an independent pinger system.
REPMUS is a NATO exercise featuring robotic systems being operated underwater, on the surface and in the air. The Royal Navy's Project HECLA team took a range of autonomous systems to operate within the program. The ecoSUB AUV missions were relatively limited due to a lack of support boats during the window of operations, but great to see it complete a couple of small, but perfectly executed missions, with the new Nortek DVL providing an excellent aide to navigation.
One of ecoSUB's recent customers have installed a transit and launch facility in their Hydrogen fuel cell powered XLAUV for multiple ecoSUBu5 micro-AUVs. At 4kg and maintaining a cylinder rule, the ecoSUBu5 is ideal for autonomous launch systems such as this. The ecoSUBu5 has previously been launched by uncrewed surface vehicles and fixed winged aerial drones, so launch by a mother-ship AUV completes Air, Surface and Underwater autonomous deployment - a first for an AUV system.
Launch of the ecoSUBu5 happened on 15 July 2022 as part of a demonstrator mission, where the micro-AUV transited to the surface and sent a status message to the users command and control center.

The NEW ecoSUBm5-Power+ AUV out on trials
One of our most recent ecoSUB AUV customers, Dr Adrian Nightingale, based at University of Southampton is currently recruiting for a PhD. This exciting opportunity involves the development of chemical sensors to be integrated on an ecoSUBu5 AUV platform.

Iain and Ayana from the ecoSUB team joined Matt Taylor and Oban Jones from the autonomous systems group at Plymouth Marine Laboratory to spend the day running some missions with one of their ecoSUBm5 AUVs. The group at PML are preparing to do some seabed video surveys using their ecoSUB AUVs and were running some trial missions. Iain and Ayana tagged along to share experience and provide support.
Iain and Alex were working from a beach in Southampton yesterday, running missions with the ecoSUBm5-Hydrocarbon Sniffer AUV, our low cost platform available with the Seabird Scientific SeaOWL sensor for oil in water detection and a Valeport CT sensor for conductivity and temperature.
The missions were run to allow colleagues from Oil Spill Response Limited (OSRL) and Blue Ocean Monitoring the chance to see the vehicle up close and appreciate the speed of data availability. As part of the work, OSRL received full data sets immediately after each mission and integrated it into their mission control platform for data visualisation. This process was tuned during the day and allowed full output within minutes of a mission finishing.
The ecoSUB AUV demonstrated its ease of use, ability to be operated with very little infrastructure and performed perfectly, completing all missions and providing useful data.
