Inertial Measurement Unit Error Modeling Tutorial: Inertial Navigation System State Estimation with Real-Time Sensor Calibration

IEEE Control Systems, 2022
Autonomous vehicle technology is rapidly advancing (see “Summary”). A key enabling factor is the advancing capabilities and declining cost of computing and sensing systems that enable sensor fusion for awareness of the vehicle’s state and surroundings ...

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.

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

A CMOS-MEMS Inertial Measurement Unit

2010 IEEE Sensors, 2010
This paper introduces the first monolithic integration of a 3-axis accelerometer, a 2-axis magnetometer and a fullcustom front-end electronics. This complete Inertial Measurement Unit (IMU) has been designed on a single die of 7.5mm² in a 0.35μm CMOS technology.

Multiple Synchronized Inertial Measurement Unit Sensor Boards Platform for Activity Monitoring

IEEE Sensors Journal, 2020
The synchronization between wireless sensor nodes is a big issue in all those low-cost systems in which each node performs measurements using its own sensors and stores the measured values locally.

MEMS based Inertial Measurement Units

2015 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP), 2015
Inertial Measurement Units (IMU) are essentially a combination of acceleration and rotation rate sensors, generating acceleration and attitude information. For strategic applications, like outer space launchers, traditional macro-scale technologies are currently employed, owing to their very high accuracies and low drift.

The Rise of Inertial Measurement Units

2017
An inherent aspect of the development of wearable and wireless systems has been the progressive evolution of the inertial measurement unit. Although when preliminarily recommended for quantifying the aspects of human movement, the inertial measurement was not sufficiently developed for application as a wearable and wireless system.

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.
