On the Design of Attitude-Heading Reference Systems Using the Allan Variance
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016The Allan variance is a method to characterize stochastic random processes. The technique was originally developed to characterize the stability of atomic clocks and has also been successfully applied to the characterization of inertial sensors. Inertial navigation systems (INS) can provide accurate results in a short time, which tend to rapidly ...

Rotation and acceleration based adaptation for attitude and heading reference system
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013In this paper, a new adaptive method is proposed for Attitude and Heading Reference System (AHRS) using MEMS IMU sensors. In this work, Euler angles calculation using gyro-scope outputs is combined with the estimation of these angles by using accelerometer and magnetometer. Kalman filtering technique is used for this fussion.

Human movement detection using attitude and heading reference system
Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments, 2014Among different types of human movement, falls are the most important since they related with high social and economic costs. Falls can cause various unintentional injuries such as fractures or in the worst-case scenario even lead to death, elderly citizen.
