Experimental evaluation of Net-LBL: an acoustic network-based navigation system
(CMRE, 2019/06)
This paper describes the use and in-field evaluation of a Networked-Long Base Line system (Net-LBL) where a network of underwater nodes cooperate to support the localisation and navigation of mobile vehicles. To avoid the ...
Real-time underwater positioning and navigation of an AUV in deep waters
(CMRE, 2019/05)
Due to the absence of GPS, navigation of autonomous vehicles underwater requires the integration of various measurements to provide the best location estimate. Usually in littoral waters, adequate navigational accuracy may ...
Real-time clock synchronisation in underwater acoustic networks
(CMRE, 2019/06)
This paper proposes an algorithm for real-time clock synchronisation in underwater acoustic networks. The algorithm models modem clocks as linear functions and embeds the data necessary for the clock synchronisation procedure ...
Dynamic placement of a constellation of surface buoys for enhanced underwater positioning
(CMRE, 2019/06)
This paper addresses the challenge of dynamically adapting the location of the nodes in an acoustic network to optimise the localisation performance of Autonomous Underwater Vehicles (AUVs) operating in the area. A dynamic ...
A robust, opportunistic clock synchronization algorithm for ad hoc underwater acoustic networks
(CMRE, 2019/06)
The proliferation of deployed sea-going autonomous platforms, such as autonomous underwater vehicles (AUVs), unmanned surface vehicles (USV), and sensor nodes anchored to the seabed, makes the deployment of true underwater ...
Localisation using undersea wireless networks
(CMRE, 2019/05)
Underwater navigation for Autonomous Underwater Vehicles (AUVs) is a challenging task, requiring a trade-off between performance, costs and operational time. The project Network Long Base Line (Net- LBL) proposes a system ...
