Autonomous Underwater Vehicle Navigation via Sensors Maximum-Ratio Combining in Absence of Bearing Angle Data [PDF]

Journal of Marine Science and Engineering, 2023
This paper proposes a maximum-ratio combining sensor fusion scheme for using an extended Kalman filter in the underwater vehicle positioning task by means of communication devices (buoys) providing location information using a slant-range mechanism ...

Simple yet stable bearing-only navigation [PDF]

, 2010
This article describes a simple monocular navigation system for a mobile robot based on the map-and-replay technique. The presented method is robust and easy to implement and does not require sensor calibration or structured environment, and its ...

Mobile bearing shows larger rollback motion than fixed bearing in total knee arthroplasty using a medial stabilising technique with a navigation system

Journal of Experimental Orthopaedics
Purpose This study aimed to investigate the intraoperative knee kinematics of cruciate‐retaining total knee arthroplasty with a medial stabilising technique (MST‐TKA) and compare the kinematics between mobile‐ and fixed‐bearing MST‐TKAs.

Precision of navigated and conventional open-wedge high tibial osteotomy in a cadaver study

European Journal of Medical Research, 2010
High tibial osteotomy (HTO) is an established treatment option for isolated medial osteoarthritis in young and active patients. One important factor for success of this procedure is the degree of correction of the weight-bearing line.

Radio-Frequency Interference Considerations for Utility of the Galileo E6 Signal Based on Long-Term Monitoring by ARFIDAAS

Navigation, 2023
The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency interference (RFI) monitoring ...

Show me the way to Monte Carlo: density-based trajectory navigation [PDF]

, 2007
We demonstrate the use of uncertain prediction in a system for pedestrian navigation via audio with a combination of Global Positioning System data, a music player, inertial sensing, magnetic bearing data and Monte Carlo sampling for a density following ...

Navigation Method for Autonomous Robots in a Dynamic Indoor Environment

International Journal of Automation and Smart Technology, 2013
The present paper considers issues related to navigation by autonomous mobile robots in overcrowded dynamic indoor environments (e.g., shopping malls, exhibition halls or convention centers). For robots moving among potentially unaware bystanders, safety

GpsTunes: controlling navigation via audio feedback [PDF]

, 2005
We combine the functionality of a mobile Global Positioning System (GPS) with that of an MP3 player, implemented on a PocketPC, to produce a handheld system capable of guiding a user to their desired target location via continuously adapted music ...
