Inertial navigation systems suffer from drift errors that degrade their performance. Main current techniques mitigate such errors by detecting stance phases under the specific context of pedestrian walking with a foot-mounted inertial measurement unit (IMU). Existing approaches achieve acceptable performances only in simple circumstances, such as smooth movements and short periods of time. In addition,...
Navigation of underwater vehicles has been and remains a substantial challenge to all underwater platforms.With the emergence of new applications and the growing acceptance of autonomous underwater vehicles (AUVs) in both military and civilian institutions, comes the need for enhanced accuracy and robustness, sustainability, and de-risking. This paper reports the development and experimental evaluation...
This paper describes a method for fusing an inertial position measurement from an Ultra-Short Baseline (USBL) sonar with a water-relative velocity measurement (from DVL, ACM, or other device) to improve knowledge of an underwater vehicle's inertial position. The goal is accuracy sufficient to enable closed-loop position control in the midwater. In this paper we describe the implementation of a kinematic...
