Position and Attitude Control of an Underactuated Autonomous Underwater Vehicle [PDF]

, 1996
The paper considers control of an autonomous underwater vehicle (AUV) with a reduced number of actuators. A nonlinear model describing both the dynamics and the kinematics of an AUV is studied. A continuous periodic time-varying feedback law is presented.

Brief Analysis of GNSS and LNSS Vulnerabilities with the Focus on Spoofing for the Marine Autonomous Surface and Undersea Vehicles

Ural Radio Engineering Journal, 2020
Positioning and navigation problems have proven to be well-developed in all areas of the Earth (on the surface of the lithosphere and hydrosphere, in the atmosphere, troposphere and stratosphere), except the hydrosphere. This article is devoted to the problem of a analysis of the state of the underwater positioning and navigation and practically the ...

BOLTZMANN ENTROPY FOR UNDERSEA TERRAIN AIDED NAVIGATION [PDF]

, 2020
The ability to navigate accurately without Global Positioning Systems (GPS) or beacon systems remains an elusive yet important capability for unmanned systems. Reliance on external beacon systems, like GPS and long baseline, create system vulnerabilities
