Newtonian Inertial Navigation [PDF]

Journal of Navigation, 1967
Newton'sPrincipia contains a neglected passage, which is nevertheless the true source of inertial navigation, occurring in De Motu Corporum Liber Primus, toward the end of ‘Sect. X. De Motu Corporum in Superficiebus datis, deg; Funipendulorum Motu reciproco’ as ‘Corol. 2’ to Prop. LIII. Prob. XXXV.

New mechanization equations for aided inertial navigation systems [PDF]

Inertial navigation equations are developed which use area navigation (RNAV) waypoints and runway references as coodinate centers. The formulation is designed for aided inertial navigation systems and gives a high numerical accuracy through all phases of

Efficient Marginalized Particle Smoother for Indoor CSS–TOF Localization with Non-Gaussian Errors

Remote Sensing, 2020
The time-series state and parameter estimations of indoor localization continue to be a topic of growing importance. To deal with the nonlinear and positive skewed non-Gaussian dynamic of indoor CSS–TOF (Chirp-Spread-Spectrum Time-of-Flight) ranging ...

Reducing Personalization Time and Energy Cost While Walking Outdoors with a Portable Exosuit

Advanced Robotics Research, EarlyView.
Rapid Real‐World Optimization! An AF‐based human‐in‐the‐loop optimization strategy rapidly personalizes a portable hip extension exosuit for incline walking. Real‐time Bayesian optimization of assistive force significantly reduces metabolic energy—up to 16.2%—while converging in just 3 min 24 s.

An IMM-Aided ZUPT Methodology for an INS/DVL Integrated Navigation System

Sensors, 2017
Inertial navigation system (INS)/Doppler velocity log (DVL) integration is the most common navigation solution for underwater vehicles. Due to the complex underwater environment, the velocity information provided by DVL always contains some errors.

Planar-based visual inertial navigation

2015 International Conference on Location and GNSS (ICL-GNSS), 2015
This paper investigates the problem of visual-inertial navigation. The proposed navigation system integrates inertial information from an inertial measurement unit (IMU) with visual data from a camera to provide relative pose estimation for a system which is navigating in an unknown structural environment.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
