Robust Singular Smoothers for Tracking Using Low-Fidelity Data

RSS 2019poster

Tracking underwater autonomous platforms is often challenged by noisy, biased, and discretized input data. Classic filters and smoothers based on standard assumptions of Gaussian white noise break down when presented with any of these challenges. Robust models (such as the Huber loss) and constraint…

Towards real-time under-ice acoustic navigation at mesoscale ranges

ICRA 2015poster

This paper describes an acoustic navigation system that provides mesoscale coverage (hundreds of kilometers) under the ice and presents results from the first multi-month deployment in the Arctic. The hardware consists of ice-tethered acoustic navigation beacons transmitting at 900 Hz that broadcast…
