Deploying long‐range autonomous underwater vehicles (AUVs) mid‐water column in the deep ocean is one of the most challenging applications for these submersibles. Without external support and speed over the ground measurements, dead‐reckoning (DR) navigation inevitably experiences an error proportional to the mission range and the speed of the water currents. In response to this problem, a computationally...
Terrain‐aided navigation (TAN) is a localisation method which uses bathymetric measurements for bounding the growth in inertial navigation error. The minimisation of navigation errors is of particular importance for long‐endurance autonomous underwater vehicles (AUVs). This type of AUV requires simple and effective on‐board navigation solutions to undertake long‐range missions, operating for months...
This paper introduces Autosub Long Range 1500, the latest addition to the Autosub family of AUVs, designed built and operated by the National Oceanography Centre, UK. The vehicle is currently in advanced stages of development, with a prototype and sea-trials planned for early 2018. Following the trials, the vehicle will begin a full programme of marine science activities from 2019 onwards. This paper...
This paper investigates the potential of use of Terrain Aided Navigation (TAN) methods to exploit the extended endurance capabilities of an enhanced 1500m depth rated variant of the Autosub Long Range (ALR), the ALR1500 Autonomous Underwater Vehicle (AUV), for operations under the Arctic ice. A simulator for the TAN system using a low resolution Arctic bathymetric map is developed to study the capability...
In 2014, funded by the European Commission through the Marie Curie Programme, ten leading European research institutes and companies in underwater robotics formed the ROBOCADEMY Initial Training Network (ITN). The objective of the network is to educate young researchers from Europe and abroad in the development and application of underwater robots. The ROBOCADEMY training programme comprises of scientific...
