Ranger 2 Family of USBL Positioning Systems case studies
Micro. For when good is good enough
Micro-Ranger 2 is our smallest ever Ultra-Short BaseLine (USBL) system, designed for first-time users to unpack, install and start tracking. It’s providing an easy to deploy yet important tool for monitoring coastal habitats in Australia, as Fathom Pacific’s Director and Principal Consultant Dr Adrian Flynn sets out for us.

Mini-Ranger 2. Recovering lost history
Mini-Ranger 2 offers many of the features of our top performing system, but is smaller, making it ideal for temporary use on chartered workboats. Recently, it’s been in service with James Fisher Marine Services who are helping to raise a piece of otherwise lost World War II aviation history.

Ranger 2 – it’s anything but standard.
With our Ranger 2 permanently installed onboard the RRS James Cook, a team from the UK’s National Oceanography Centre (NOC) was able to significantly reduce the uncertainty around the position of their autonomous underwater vehicle (AUV).
