On the use of IMU (inertial measurement unit) sensors in geomorphology

Earth Surface Processes and Landforms, 2021
AbstractInertial measurement units (IMUs) are mobile sensors assemblies constructed using a combination of MEMS (micro electrical mechanical systems) accelerometers, gyroscopes and magnetometers. Both the technology and its applications to geomorphic problems are developing rapidly, since they demonstrate the prospect of monitoring individual sediment ...

Wireless inertial measurement unit (IMU)-based posturography

European Archives of Oto-Rhino-Laryngology, 2019
Classical posturography techniques have been recently enhanced by the use of different motion tracking devices, but for technical reasons they are not used to track directly the body spatial position of a subject.To describe and clinically evaluate a wireless inertial measurement unit-based mobile system to track body position changes.The developed ...

Validity, reliability and accuracy of inertial measurement units (IMUs) to measure angles: application in swimming

Sports Biomechanics, 2021
The first objective was to test the validity, reliability and accuracy of paired inertial measurement units (IMUs) to assess absolute angles relative to Vicon and OptiTrack systems. The potential impacts of slow vs. rapid and intermittent vs. continuous movements were tested during 2D laboratory analyses and 3D ecological context analysis.

Tracking Using an Inertial Measurement Unit (IMU) and GPS

Applied Mechanics and Materials, 2012
Since the last decade, vehicle tracking has been attracting significant attention in a wide range of applications. To deliver on their requirements, these applications need a specific tracking accuracy. However, current tracking techniques lack the required accuracy, especially for mission critical applications.

High-precision inertial measurement unit IMU-5000

2018 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL), 2018
Today interferometric fiber-optic gyroscopes (FOGs) reach ultimate theoretical performance and surpass well-established competitor, the ring laser gyroscopes. Due to its inherent low random noise and its scalability, FOG technology is one of the very few technologies able to cope with the applications requiring the highest performance.

An inertial measurement unit (IMU) for an autonomous wireless sensor network

Proceedings of 6th Electronics Packaging Technology Conference (EPTC 2004) (IEEE Cat. No.04EX971), 2005
This paper will present the work done in designing and fabricating an autonomous inertial measurement unit (IMU) panel for a novel 25mm wireless sensor network platform. This panel increases the sensory capabilities of each node allowing the orientation of each node to be completely realised.

Honeywell gun-hard inertial measurement unit (IMU) development

PLANS 2004. Position Location and Navigation Symposium (IEEE Cat. No.04CH37556), 2004
Honeywell has designed and manufactured a gun-hard IMU that provides the baseline for meeting the needs of DoD guided tactical munitions, as well as being a platform for commercial usage. The gun-hard IMU is a solid-state inertial sensor package that measures and provides inertial angular rates and linear accelerations in a body-mounted strap-down ...

Embedded Kalman Filter for Inertial Measurement Unit (IMU) on the ATMega8535

2012 International Symposium on Innovations in Intelligent Systems and Applications, 2012
The Kalman Filter is very useful in prediction and estimation. In this paper, the Kalman Filter is implemented for Inertial Measurement Unit (IMU) on the ATMega8535. The sensors used in this system are accelerometer MMA7260QT and gyroscope GS-12. The system chooses the arbitrary sampling time and then it is evaluated for possible using smaller value ...

GPS and Inertial Measurement Unit (IMU) as a Navigation System for the Visually Impaired

2012
The current GPS (Sirf 3) devices do not give the right heading when their speed is less than 10 km/h. This heading is also less reliable when the GPS is used in the big cities where it is surrounded by buildings. Another important problem is that the change of orientation of the visually impaired needs a long delay to be detected by the GPS due to the ...
