Inertial Measurement Unit for Trajectography

2021 2nd International Conference on Range Technology (ICORT), 2021
This document presents a technological breakthrough regarding electro-optics systems used for accurate measurement of the position of flying objects in Test Ranges. The innovation presented here consists in using an “Inertial Measurement Unit” (IMU) installed as close as possible to the optronic sensors in the core of the payload.

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 ...

Compact MEMS magnetometers for inertial measurement units

2012 IEEE Sensors, 2012
This work discusses the performance, in particular in terms of minimum obtainable resolution, for Lorentz force based MEMS magnetometers, both accounting for technological constraints (minimum air gap, package pressure, standard industrial process, …) and considering the final application in consumer electronics (bandwidth, noise, full scale range and ...

Automatic calibration for inertial measurement unit

2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012
The nine degrees-of-freedom (DOF) inertial measurement units (IMU) are generally composed of three kinds of sensor: accelerometer, gyroscope and magnetometer. The calibration of these sensor suites not only requires turn-table or purpose-built fixture, but also entails a complex and laborious procedure in data sampling.

Calibration of an Inertial Measurement Unit

International Applied Mechanics, 2017
A new method for the calibration of inertial measurement units of strapdown inertial technology is proposed. Such a unit consists of accelerometers, gyroscopes, and a signal processing system. The method of test turns and rotations on a rotary table is used to calibrate the inertial measurement unit.

Inertial measurement units on micromechanical sensors

IEEE Aerospace and Electronic Systems Magazine, 2008
This presents a micromechanical gyroscope (MMG), an inertial measurement unit (IMU)based on MMG and an integrated inertial-satellite attitude and navigation system (IANS) developed in CSRI Elektropribor. The evolution and prospects for the development of MMG main components and MMG-based systems is considered. The test results are given.

Measuring Arm Motions Using the Inertial Measurement Unit

2020 IEEE 2nd Global Conference on Life Sciences and Technologies (LifeTech), 2020
This paper describes how to detect arm motions using Inertial measurement unit (IMU). The authors propose a method to attach the IMU to an upper arm and a lower arm as so to obtain the arm’s attitude information from the sensor’s data and thereby to detect the arm’s motions. Our experiment has shown that the arm’s flexion can be detected.

Calibration of an inertial measurement unit

2013 16th International Conference on Advanced Robotics (ICAR), 2013
This paper presents a fast and low cost way to calibrate different inertial measurement sensors. In particular the calibration of an accelerometer and a gyroscope using nonlinear least squares is presented. A model of the sensors which includes the main errors that MEMS devices present is used. A calibration method is proposed for estimating the static

Low cost inertial measuring unit

IEEE PLANS 92 Position Location and Navigation Symposium Record, 2003
A concept being explored is the use of an inexpensive IMU (inertial measuring unit) with the GPS (Global Positioning System). An inexpensive IMU can meet many of the same functional requirements as the high-accuracy system, with the exception of long-term position. For example, some applications for instrumenting a reference frame are antenna stability,
